Abstract

Hoploscopa Meyrick (Lepidoptera: Crambidae) is a fern-feeding genus found in montane areas of South-East Asia and Melanesia, eastwards up to the Samoan Islands. It includes sixteen described species, with at least 70 further undescribed species known from scientific collections. An iterative approach including morphological and molecular characters was used in order to explore the diversity of Hoploscopa. The hitherto described species are revised, and descriptions authored by T. Léger and M. Nuss are provided for an additional 26 new species: H. agtuuganonensis sp. nov., H. albipuncta sp. nov., H. albomaculata sp. nov., H. anacantha sp. nov., H. boleta sp. nov., H. cynodonta sp. nov., H. danaoensis sp. nov., H. gombongi sp. nov., H. gracilis sp. nov., H. ignitamaculae sp. nov., H. isarogensis sp. nov., H. jubata sp. nov., H. kelama sp. nov., H. kinabaluensis sp. nov., H. mallyi sp. nov., H. marijoweissae sp. nov., H. matheae sp. nov., H. niveofascia sp. nov., H. pangrangoensis sp. nov., H. parvimacula sp. nov., H. pseudometacrossa sp. nov., H. sepanggi sp. nov., H. sumatrensis sp. nov., H. titika sp. nov., H. tonsepi sp. nov., H. ypsilon sp. nov. Using a protocol specific for the amplification of DNA from old museum specimens, we recovered 101 COI barcodes for all but one of the newly described species, with 76 being barcode compliant (>487 bp). Species delimitation analyses suggest cryptic diversity, with six cases reflecting allopatric divergence, and two further cases found in sympatry.

Introduction

South-East Asia is home to a rich biodiversity encompassing three of the 25 world’s biodiversity hotspots (Myers et al. 2000). Pyraloidea is one of the largest superfamilies of Lepidoptera in the Oriental region, with 3,771 known species (Heppner 1998). Much of its diversity for this region remains to be described in this group (Nuss 1998, Sutton et al. 2015). Hoploscopa Meyrick best illustrates this knowledge gap, with 16 species currently described and more than 70 species awaiting description (Robinson et al. 1994). Hoploscopa moths display elongated brown forewings often with median and postmedian diagonal pale yellow to red markings. The genus is distributed across the Oriental and Australasian regions, ranging from the North of Thailand eastwards to the Samoa Islands, but is virtually absent from the tropical rainforests of Northern Queensland, Australia. A recent study reported the larvae to feed on ferns (Mally et al. 2017).

Nuss (1998) synonymised Syncrotaula Meyrick, a replacement name for Eudorina Snellen, with Hoploscopa, and transferred twelve species to it. The author also provided a checklist of the genus and described one new species. Robinson et al. (1994) erected the tribe Hoploscopini within Scopariinae for Hoploscopa (= Syncrotaula) and Perimeceta Turner. Nuss (1998) transferred the Hoploscopini to the Heliothelinae based on the shared inwardly directed spine of the corpus bursae in the female genitalia. Perimeceta, the only other genus included in the Hoploscopini, is distributed from Java to South Australia and its larvae also feed on ferns (Miller et al. 2015, Mally et al. 2017). The systematic placement of Hoploscopini is still a matter of debate, with some authors grouping them together with Heliothelini in the Heliothelinae (Nuss 1998), while others consider the Heliothelinae an ingroup of Scopariinae (Leraut 1980, Minet 1982, Munroe and Solis 1998). The first molecular-based phylogeny including representatives of Hoploscopa suggest it to represent a separate lineage outside of Scopariinae + Crambinae (Léger et al. 2019).

This paper aims at establishing an iterative approach following Yeates et al. (2011) for species discovery and description in Hoploscopa, serving as a first step of a comprehensive revision of the genus. With an iterative approach using morphology and COI barcode, we provide redescriptions for fifteen of the 16 described species and describe 26 new species. Incongruence between morphology and molecular datasets, as well as factors that possibly influenced the evolution of the group are discussed.

Materials and methods

Material acquisition

Material collected on Borneo, Java, Fiji, the Malay Peninsula, North-Sulawesi, New Guinea, the Philippines, Samoa, Sumatra and Vanuatu was obtained from the Museum für Tierkunde Dresden (MTD), the British Natural History Museum, London (NHMUK), the United States National Museum, Washington (USNM), the Museum für Naturkunde Berlin (MFNB) and the Zoologische Staatsammlung München, Munich (ZSM). Examination of the type specimens of the previously described species, all deposited at the NHMUK, was done by TL during a visit at that institution. Specimens described from Sabah, Malaysia are stored at the Institute for Tropical Biology and Conservation, Borneensis, Kota Kinabalu, Malaysia (BORN).

Iterative approach

In order to test species hypotheses with two independent sets of characters, we followed the best practice outlined by Schlick-Steiner et al. (2010), here referred to as “iterative taxonomy” (Yeates et al. 2011). This workflow started by sorting undescribed material to morphospecies based primarily on wing pattern, followed by examination of characters in male genitalia that show most variation. Subsequently, for each morphospecies, specimens with slightly differing wing pattern and/or of each collecting locality were selected for amplification of the mitochondrial COI barcode. Finally, morphospecies with at least one obtained COI barcode sequence were considered for species description (with the exception of H. marijoweissae sp. nov.). If strong divergence was observed in the COI barcode within a morphospecies, a second more careful examination of the specimens was conducted in the search of diagnostic characters, and COI barcode was sequenced for all specimens of the series. Specimens in poor conditions (i.e., wing pattern faded away, abdomen missing) or new species without male specimens available were not further considered for species description.

Molecular work

One hundred and fifty-seven dried museum specimens were considered for DNA extraction. Assuming a higher degree of degradation due to the age of the dried specimens, DNA extraction and preparation of PCR samples for specimens collected before 1990 (referred to as “old sample”) were performed in the clean-room facility of the SGN-SNSD-Mol-lab at MTD. The abdomen (one or two legs if the abdomen could not be used) was carefully removed with sterilised pincers for DNA extraction, following a non-destructive method (Knölke et al. 2004) with the NucleoSpin Tissue kit (Macherey-Nagel, Düren, Germany) according to the manufacturer’s protocol. DNA concentration of old samples was measured with a NanoDropOne spectrophotometer. We followed a workflow previously used by other authors (Hebert et al. 2013, Mitchell 2015, Hundsdoerfer et al. 2017) by amplifying up to five short overlapping fragments covering the COI barcode part (see Suppl. material 1: Fig. S1). Primers, amplicon length and amplicon overlap are listed in Suppl. material 2: Table S1. In the first step (recently collected samples only), amplification of the whole COI barcode sequence (658 bp) was attempted with the primer pair HybLCO/HybNancy, each flanked with universal primer tails (“Hyb-”) facilitating sequencing (Wahlberg and Wheat 2008). If amplification was not successful, we proceeded in the second step with the amplification of fragments 1a (LepF1/K699) and 1b (f220/LepR1 or HybNancy). The latter reverse primer showed a slightly better performance with respect to the amplification of fragment 1b and was preferentially used. If amplification of fragments 1a or 1b in step two failed, we proceeded in step three with amplification of fragments A, B, C (covering fragment 1a) and C, D, E (covering fragment 1b). PCR-mix included 2 µl of BIORON complete buffer 10× incl. Mg2+ (25 mM), 2 µl of each primer at 10pmol/µl, 0.4 µl of dNTP (each 10 mM), 0.2 µl of Taq polymerase BIORON (Bioron DFS Taq, Ludwigshafen, Germany) ,1 µl (recent samples) or 1 to 8 µl (old samples) of DNA (depending on the quantity of DNA measured) and filled up with water to final volume of 20 µl. Alternatively, the AccuStart II GelTrack PCR SuperMix (2×) (Quanta BioSciences, Beverly, USA) ready-to-use mix was used in the following PCR-mix: 6.5 µl AccuStart ready-to-use-mix, 1 µl of each primer, 1–8 µl DNA and filled up with water to final volume of 25 µl. Initial denaturation at 95 °C during 5 min was followed by 42 cycles of 30 sec denaturation at 95 °C, 40 sec hybridisation at 49 °C, 50 sec elongation at 72 °C, with a final elongation at 72 °C for 10 min. Amplification success was checked by electrophoresis on 1 or 2% agarose gels, subsequently stained with GelRed and visualised under UV light. Sequencing was performed by Macrogen (Netherlands) using the original PCR primers or the T7 and T3 sequencing primers (Wahlberg and Wheat 2008). Full COI-barcoding PCR products were sequenced in the forward direction only, while the shorter PCR products were sequenced in both directions.

Data analyses

Sequences were checked by eye and concatenated using PHYDE 0.9971 (Müller et al. 2005). In order to assess the amplification of the correct fragment, sequences were blasted with the blastn program against the nucleotide collection (nt), as provided by the National Center for Biotechnology Information (NCBI). In order to identify potential nuclear pseudogenes, sequences were searched for indels, internal stop codons and double peaks in electropherograms, as suggested in Song et al. (2008). Newly generated sequences (including ENA and BOLD accession numbers), as well as sequences retrieved from Barcode of Life Data System (BOLD, http://v4.boldsystems.org/) are reported in Suppl. material 3: Table S2. For the phylogenetic analyses, PartitionFinder2 (Lanfear et al. 2017) was used to determine the best partitioning scheme using the AICc model and the greedy search algorithm (Lanfear et al. 2012). Partition for each of the three codon positions was recovered as the best model and subsequently used for further analyses. Maximum Likelihood (ML) analysis was performed with RAxML (Stamatakis 2006) as implemented on the CIPRES portal (Miller et al. 2010), using the GTR+GAMMA substitution model and the best PartitionFinder scheme. Node support was estimated with 1000 thorough bootstrap replicates using the same algorithm.

Species delimitation

Two different methods were used to investigate species delimitation in our molecular dataset: Automatic Barcode Gap Discovery (ABGD) (Puillandre et al. 2012) and General Mixed Yule-coalescent method (GMYC) (Pons et al. 2006, Fujisawa and Barraclough 2013). These popular methods have been repeatedly used in DNA barcoding studies on Lepidoptera (Kekkonen and Hebert 2014, Dincă et al. 2015, Dumas et al. 2015, Nakahara et al. 2019). We noticed a detrimental effect of non-compliant barcode sequences (< 487 bp) on the estimation of species in densely sampled clades (n > 2), where these sequences were flagged as new species. Consequently, these sequences were removed to generate a COI_487 bp dataset. Distance-based analysis ABGD was calculated using the K80 Kimura distance model and X fixed to 0.5 on the dedicated platform (https://bioinfo.mnhn.fr/abi/public/abgd/abgdweb.html). Genetic distances are referred to as K2P-dist throughout the text.

The ultrametric tree required for the GMYC analysis was generated using BEAST 1.10.4 (Suchard et al. 2018). The COI dataset was partitioned after codon position accordingly to the best PartitionFinder2 scheme. An uncorrelated relaxed clock with lognormal distribution was used and the Speciation: Yule Process model was set as tree prior model and other parameters were left unchanged. MCMC chain was set to 40 million generations, sampled every 1000th generation. Convergence was checked on Tracer (Rambaut et al. 2018) and the first 4 million generations were discarded as burnin. Species delimitation analysis was performed using the GMYC method as implemented in the R-package SPLITS (Ezard et al. 2009, Fujisawa and Barraclough 2013). The single-threshold option was used as suggested in Fujisawa and Barraclough (2013).

Systematic treatment

Genitalia were mounted following the method of Robinson (1976). Photographs of the habitus of imagines were taken with an Olympus E-M1 with the Olympus M. Zuiko Digital ED 60 mm f/2.8 Macro Lens. Photographs of genitalia and measurements were performed on a Nikon Eclipse 90i at the MTD. Images were subsequently enhanced on Adobe Photoshop CS6 and illustrations plates were created on Adobe Illustrator CS6. Collecting data of holotypes was copied exactly as found on the labels, with vertical bars to mark line breaks. Abbreviations or translations are given in square brackets where judged meaningful. Paratype data are reported by country in alphabetical order, with information reported without indication of line change. Collecting localities are reported as written on labels. Dates and collectors’ information were standardised and the latter placed in parentheses. The specimen depositories are reported with the use of the corresponding acronyms. GPS coordinates for localities were retrieved from the online platform geographic.org (https://geographic.org/geographic_names/) using the database of the National Geospatial-Intelligence Agency. Localities treated in this paper are reported in Table A1 in Appendix 1. Specimens whose conspecificity was uncertain were listed under “Other specimens examined”. Nomenclature follows that of Landry (1995), except for the use of the term phallus (Kristensen 2003). The colours “bronze”, “ochre”, and “tawny” refer to the Wikipedia list of colours by shade for brown (https://en.wikipedia.org/wiki/Category:Shades_of_brown). Character description was facilitated by the use of Mesquite (Maddison and Maddison 2017) where each character was given a state, thereby allowing a better visualisation of character state variation as well as warranting consistency among species descriptions.

Results

Molecular dataset

We obtained 101 COI barcodes ranging in length from 261 to 658 bp (mean length = 545 bp), among them 76 barcode “compliant sequences” (> 487 bp) according to Hebert et al. (2013). Ten non-compliant barcode sequences were kept in the final dataset for species with no or one barcode sequence. Fifteen further non-compliant barcode sequences were discarded from the final dataset (see Suppl. material 2: Tab. S1). We recovered the COI barcode for all but one (H. marijoweissae sp. nov.) species described in this paper and for seven of the sixteen previously described species. Twenty-five Hoploscopa sequences, as well as 13 sequences from the hypothesised sister-group Perimeceta were retrieved from BOLD and added to our dataset, totalling 126 COI barcode sequences including nine of the described species. Eleven species were represented by only one barcode sequence. Recovered fragments and total sequence length are summarised in Suppl. material 3: Table S2. The oldest sample from which we could successfully amplify COI sequence data were collected in 1955 (63 years old). The Maximum Likelihood analysis of the COI dataset is illustrated in Fig. 123, with bootstrap support (abbr. BS) over 50 displayed on nodes. Genetic distances (K2P-dist) between all COI barcodes are reported in Suppl. material 4: Table S3.

Species delimitation

Analysis of the morphology allowed delineation of 39 species. Both ABGD and GMYC analyses highlighted 48 molecular operational taxonomic units (MOTUs) in Hoploscopa species, splitting seven of the morphospecies into two MOTUs, and one into three MOTUs (H. danaoensis sp. nov.). Six of these splits reflect allopatric divergence. In each of the two species H. matheae sp. nov. and H. parvimacula sp. nov., there is one female from the Malay Peninsula recovered as a separate MOTU from other specimens from Borneo. In H. luteomacula, the two specimens from Borneo are recovered as a distinct MOTU to that of Sumatra. In H. albipuncta sp. nov., a female from Luzon (Philippines) was recovered in a MOTU distinct from that including the specimens from Borneo. Genetic differentiation is also observed among Philippines islands: specimens of H. danaoensis sp. nov. from Danao, Negros, and Mindanao represent three different MOTUs, while specimens of H. isarogensis sp. nov. from Luzon and Leyte are also recovered into two distinct MOTUs.

Sympatric divergence is observed in H. kinabaluensis sp. nov. and H. sumatrensis sp. nov. Hoploscopa kinabaluensis sp. nov. is split into two MOTUs representing sister clades and diverging from each other by 1.7–2.2%. In H. sumatrensis sp. nov., two separate MOTUs are recovered by the ML analysis in a clade with DNA samples BC_MTD_LEP01421 (Hoploscopa sp. near sumatrensis) and BC_ZMBN_Lep00081 (larva of Hoploscopa sp.). The two H. sumatrensis MOTUs show a divergence of 4.1–6%. Second MOTU, represented by samples MTD8258 and BC_MTD_LEP01422, include only females and need examination of male specimens.

Diagnosis

Hoploscopa displays brown to dark brown forewings, often bearing pale yellow-, yellow-, or red-coloured median and postmedian diagonal stripes. In male genitalia, the uncus is well developed, the gnathos forms a ribbon-like structure, often with a posterior projection, and the vinculum bears laterally a pair of coremata. In female genitalia, the antrum is short, often sclerotised, and the corpus bursae bears a thorn, often with a basal sclerotisation. Hoploscopa is morphologically very similar to Perimeceta. The forewings of Perimeceta are slightly larger, display a yellow to brown ground colour, with one basal elliptic and one postmedian lunule-shaped white spot. In male genitalia, Perimeceta shows a spade-shaped uncus, the gnathos arms connect shortly after arising and are expanded posteriorly into an elongated tip, the valva shows a conspicuously rounded ventral margin, and is apically narrowed into a tip, while the ventral margin is more or less straight in Hoploscopa. Perimeceta exhibits female genitalia similar to those of Hoploscopa with a slender ductus bursae and a rounded corpus bursa bearing a thorn. However, the latter displays a membranous antrum in female genitalia, while it is sclerotised in most species of Hoploscopa.

Distribution

Hoploscopa is found from the Malay Peninsula and Sumatra in the West to the Samoa Islands in the East, as well as from the North of Thailand to Vanuatu and Fiji in the South. It is absent from Queensland (Australia) and New Caledonia. It is predominantly found in tropical mountain forests, with only few species encountered in the lowlands.

Biology

Host plant data is available for five Hoploscopa species, all feeding on ferns. The larvae of H. gombongi sp. nov., H. obliqua and H. tonsepi sp. nov. from Papua New Guinea are reported from Diplazium esculentum (Retzius in Retzius & König, 1791) Swartz, 1803 (Athyriaceae) (Miller et al. 2015, Mally et al. 2017). Another undescribed Hoploscopa species (sample USNM_ENT_00739239) from Papua New Guinea is reported from Sphaerostephanos unitus (Linnaeus, 1759) Holttum, 1794 (Thelypteridaceae) (ibid). Lastly, one undescribed Hoploscopa species from Borneo is reported from the fern Dicranopteris linearis (Burman, 1768) Underwood, 1907 (Gleicheniaceae) (Mally et al. 2017).

Corpus bursae small, globular, reticulate, with barely marked sclerotisation at thorn base. Thorn curved, with small dents pointing toward thorn apex on its inner side, glabrous on the outer side.

Distribution

Known from the slopes of the Mount Kinabalu (4,095 m) on Borneo, at altitudes between 1,700 m and 2,000 m.

DNA barcoding

Specimen MTD7430 from Luzon shows an K2P-distance of 4.5–4.9% with the two specimens from Borneo.

Etymology

The species name albipuncta refers to the Latin albus, white, and punctus, forming a point.

Remarks

Two female specimens from the Philippines with similar habitus and genitalia but a COI barcode divergence of 4.5–4.9% are recovered as different MOTU in the species delimitation analyses. Unfortunately, no male was available for this study, thus we refrained from describing a new species based on these two specimens.

Similar species

No similar species known.

Description

Head. Antennae dorsally with pale yellow scales. Proboscis dark brown. Maxillary palpi dark brown, basally and inwardly pale yellow. Labial palpi dark brown, ventro-basally pale yellow.

Thorax (Fig. 1). Thorax dark brown, with two pale yellow stripes laterally and one dorsally. Collar pale yellow. Forewing length: 10 mm (♂ & ♀); forewing ground colour dark brown, with darker scales at its base; basally with a roughly defined Z-line pale yellow; basal and distal discoidal stigma of a darker brown, circled with pale yellow, median discoidal stigma therebetween dark red in some specimens; broad median triangular pale yellow patch near dorsum, connected distally by a line to postmedian triangular pale yellow patch; subterminal pale yellow line following median line shape, originating at distal 1/4 of dorsum, inwardly incurved between A1+2 and Cu2, costally diverging toward apex; subterminal field broadly marked with scales of a lighter brown; fringes dark brown, with pale yellow dots. Hindwing pale brown. Forelegs dark brown. Midlegs brown; femur and tibia distally pale yellow; tarsi pale yellow. Hindlegs dark brown, femur-tibia articulation pale yellow; tibia distally pale yellow; tarsi bronze.

Abdomen. Male sternum A8 posterior margin straight.

Male genitalia. (N = 1) (Fig. 47). Uncus broad, narrowing on distal half, with apex truncate. Gnathos without posterior projection. Valva ventral margin slightly concave, bent dorsad on apical 1/5; dorsal margin conspicuously convex; apex blunt. Juxta with base slightly quadrangular, medially narrow, apex broadly incurved. Saccus not pronounced.

Female genitalia (N = 2) (Fig. 88). Anterior apophyses with dorsal tip pointed dorsad at posterior 1/3. Antrum sclerotisation twice as long as broad. Ductus bursae of medium length, roughly straight. Corpus bursae pear-shaped, reticulate on posterior half, sclerotised between thorn and corpus opening. Thorn straight, with small dents pointing toward thorn apex, basally with small outwardly projected extension.

Distribution

Known from the Malay Peninsula, and Borneo (Brunei, Mount Kinabalu), at altitudes between 1,300 m and 1,600 m.

DNA barcoding

Specimen MTD8244 from the Malay Peninsula shows an K2P-distance of 2.2% with the two specimens from Borneo. It is recovered as a distinct MOTU in the species delimitation analyses. Specimens from Kinabalu and Tawau Hills share identical COI barcodes. No COI barcode was obtained for the specimen from Brunei (MTD8245).

Etymology

The species is named after Mathéa Léger, sister of the first author.

Remarks

One specimen from the NHMUK collected on Mount Tengger (Indonesia, Java) in 1934 shares a similar wing pattern and thus potentially represents a conspecific specimen. Unfortunately, the abdomen of the specimen was missing. Specimen MTD8244 from the Malay Peninsula shows minor differences in wing pattern with those from Borneo: costal field, median discoidal stigma and subterminal field are dark red, and base of thorn on corpus bursae is thinner.

Diagnosis

This relatively small-sized species (forewing length 8–10 mm) shows brown forewings with red markings edged with pale yellow. The median discoidal stigma is oval, red, edged with pale yellow, median cubital patch is reduced to a small streak and median dorsal patch is absent. The postmedian patch consists of a mix of red and brown scales, at costa forming triangular pale yellow patch. Male genitalia are unique in the conspicuously incurved ventral margin of the valva, medially extending into a tip pointing ventrad. In female genitalia, the corpus bursae is small, globular, and bears a crest of sclerotised acanthae between thorn and corpus opening.

Similar species

Hoploscopa isarogensis sp. nov.; to a lesser extent H. mallyi sp. nov., H. agtuuganonensis sp. nov., H. gracilis sp. nov., H. ignitamaculae sp. nov. Median cubital and dorsal patches form with the median discoidal stigma a disrupted pale yellow band (median dorsal patch not marked in H. mallyi sp. nov.), and postmedian pale yellow marking at costa is reduced to a blotch in above listed species. Hoploscopa gracilis sp. nov. and H. mallyi sp. nov. are slightly larger (9–12 mm). Comparison of the male genitalia allows unequivocal separation from these species. In female genitalia, H. isarogensis sp. nov. displays a narrower and slightly longer ductus bursae and a larger corpus bursae with large curved thorn, while it is small and straight in H. cynodonta sp. nov. Female genitalia of H. mallyi sp. nov., H. agtuuganonensis sp. nov., and H. gracilis sp. nov. share the broad ductus bursae, the small globular corpus bursae with H. cynodonta sp. nov. but have a longer ductus bursae, and the sclerotisation of corpus bursae is large and diffuse.

Description

Head. Antennae dorsally with pale yellow scales. Proboscis brown to pale brown. Maxillary palpi brown, base and inner side pale yellow. Labial palpi brown, ventrally pale yellow.

Thorax (Fig. 6). Collar white. Forewing length: 8–10 mm (♂), 8 mm (♀); forewing ground colour brown; basal longitudinal red streak basally surrounded with pale yellow U-shaped spot; costal field red; median discoidal stigma oval, red with pale yellow edges; median cubital patch forming longitudinal pale yellow rectangle; postmedian patch red, with basal edge pale yellow, distally abutted with pale yellow triangular costal patch; postmedian line costally marked; postmedian suffusion of pale yellow and pale brown scales, distally edged by pale yellow subterminal line; subterminal field marked with red; fringe chequered pale yellow and brown. Hindwing pale brown. Forelegs and midlegs brown. Hindlegs with femur brown; tibia pale yellow, distally brown; tarsi bronze speckled with pale yellow.

Abdomen. Male sternum A8 posterior margin forming two conspicuous triangular tips, with short, rounded lateral projections.

Male genitalia (N = 2) (Fig. 49). Uncus medially slightly widened, narrowing toward apex, apex duck beak-shaped, medio-ventrally with a bump and two ridges. Gnathos projection roughly triangular, ca. 1/4 of uncus length, with rounded apex. Valva ventral margin with basal half sclerotised, at 1/4 conspicuously incurved into a semi-circle, protruded medio-ventrally into a tooth-like tip pointing ventrad; valva dorsal margin convex, apex truncate. Juxta with base rounded, medially narrowed, apical half laterally protruded, apex broad, not sclerotised. Saccus quadrangular, conspicuously produced anterad.

Female genitalia (N = 1) (Fig. 90). Posterior apophyses bent ventrad. Anterior apophyses with small dorsal bump at 1/3. Antrum sclerotisation twice as long as broad, barely sclerotised. Ductus bursae of medium length, broad, with a narrow loop before corpus bursae. Corpus bursae globular, reticulated, with crest of sclerotised acanthae between thorn and corpus opening. Thorn straight, slightly incurved at apex, with small dents pointing toward thorn base.

Distribution

Known on Borneo from Brunei to the Mount Kinabalu, the Mount Monkobo (1,759m) and the Tawau Hills in Sabah (Malaysia), at altitudes between 300 and 1,700 m.

DNA barcoding

Specimens MTD LEP3066 from Mount Kinabalu and MTD7425 from Tawau Hills differ by 0.4%. The nearest neighbour is H. isarogensis sp. nov. from the Philippines (K2P-dist = 2.3–3%).

Etymology

Formed by apposition of the Greek words cyno-, of the dog, and odous, tooth, referring to the conspicuous tooth-like extension on the ventral margin of the valva in male genitalia.

Mally (MFNB).

Diagnosis

Hoploscopa parvimacula sp. nov. displays brown forewings with reduced pale yellow markings. The median discoidal stigma is crescent-shaped, and the median cubital patch forms a streak not connected to the median discoidal stigma. The postmedian patch and postmedian area are faintly marked with pale yellow. In male genitalia, the gnathos projection is distally spatula-shaped, reaching ca. 2/3 of the uncus length, and the juxta displays blunt lateral projections and a truncate apex.

Similar species

Hoploscopa kinabaluensis sp. nov., H. pangrangoensis sp. nov. The forewings of H. kinabaluensis sp. nov. display more contrasting postmedian patch and subterminal line, and a subterminal field suffused with pale yellow. In H. pangrangoensis sp. nov., the median cubital patch is almost absent and the subterminal line is more strongly pronounced. In male genitalia, base of gnathos projection is narrower and the cornutus displays a narrow bump at apex in H. kinabaluensis sp. nov. The finger-like gnathos projection of H. pangrangoensis sp. nov. is narrower than that of H. parvimacula sp. nov. and reaches only half the uncus length. In female genitalia, ductus bursae of H. kinabaluensis sp. nov. is twice as long as in other species, with a loop on its middle and a large bow before corpus bursae. In H. pangrangoensis sp. nov., colliculum is membranous with longitudinal sclerotised lines, corpus bursae is larger and thorn is smaller.

Description

Head. Antennae dorsally striped with brown and bronze scales. Proboscis pale yellow, speckled with pale brown. Maxillary palpi dark brown, base and inner side pale yellow. Labial palpi dark brown, ventro-basally pale yellow.

Thorax (Fig. 7). Collar pale yellow. Forewing length: 9–10 mm (♂ & ♀); forewing ground colour brown; basal dark brown dash, distally pale yellow; basal and distal discoidal stigmata dark brown; median patches Y-shaped, pale yellow, disrupted with brown at vein, edged basally and distally with dark brown; postmedian patch of a lighter brown, with pale yellow triangular costal spot distally edged with dark brown; subterminal line pale yellow, distally dark brown; fringe brown, with pale yellow dots. Hindwing pale brown. Forelegs brown. Midlegs with femur brown; tibia pale yellow, speckled with brown; tarsi bronze. Hindlegs with femur brown; tibia pale yellow, speckled with brown; tarsi pale yellow to pale brown.

Abdomen. Male sternum A8 posterior margin bilobed, with short, rounded lateral projections.

Male genitalia (N = 8) (Fig. 50). Uncus medially broadened, narrowing on distal half, apex slightly obtuse. Gnathos projection ca. 2/3 of uncus length, spatula-shaped. Valva ventral margin straight, gently bent dorsad on distal 1/4, dorsal margin convex, apex rounded or slightly pointed. Juxta slender, base roughly quadrangular, apex truncate. Saccus small, pointing dorsad.

Female genitalia (N = 2) (Fig. 91). Anterior apophyses with dorsal bump at posterior 1/3. Antrum sclerotisation twice as long as broad. Ductus bursae short and straight, slightly bent before corpus bursae. Corpus bursae pear-shaped, posterior half reticulated, anterior half membranous, with diffuse sclerotisation between thorn and corpus opening, medially with faintly marked sclerotised band. Thorn short and straight, with small dents pointing toward thorn apex.

Distribution

Known from Mount Kinabalu on Borneo, at altitudes between 1,550 and 1,950 m.

DNA barcoding

Sample MTD8229 of H. parvimacula sp. nov. shows a K2P-dist of 3.1–3.4% with samples from Borneo and is recovered as separate MOTU.

Etymology

Refers to the Latin parvus, for small, and macula, for spot, referring to the Y-shaped median markings that are smaller than in other similar species.

Remarks

The specimen with DNA voucher MTD8229 belongs to a series of females from the Malay Peninsula, which are morphologically similar to H. parvimacula sp. nov. and deposited at NHMUK. Since no males of the same series were available for investigations, we restrained from drawing further conclusions here.

Diagnosis

The forewing median markings form an interrupted pale yellow Y, and postmedian patch and subterminal line are pale yellow, well-marked. In male genitalia, the gnathos projection is ca. 2/3 of uncus length, spatula-shaped, broadening toward apex, and the cornutus displays a small but conspicuous bump. Female genitalia show a long ductus bursae broadly curved twice and a large pear-shaped corpus bursae.

Similar species

Hoploscopa parvimacula sp. nov. (q.v.), H. brunnealis, H. danaoensis sp. nov., H. metacrossa. These species share similar forewing markings with H. kinabaluensis sp. nov. Male genitalia of these species show a gnathos projection larger at base, of constant width, reaching ca. half of uncus length, and a cornutus lacking the apical bump. In female genitalia, the shorter ductus bursae is nearly straight.

Description

Head. Antennae dorsally striped with pale yellow and bronze scales. Proboscis brown speckled with pale yellow. Maxillary palpi brown, base and inner side pale yellow. Labial palpi brown, ventral base and inner side pale yellow.

Thorax (Fig. 8). Thorax dorsally pale yellow, laterally brown. Collar pale yellow. Forewing length: 9.0–10.5 mm (♂), 10–11 mm (♀); forewing ground colour brown; basal dark brown dash, distally pale yellow; median discoidal stigma and median cubital patch forming together a pale yellow-coloured Y, disrupted with brown at vein, edged basally and distally with dark brown; postmedian patch roughly triangular, pale yellow, invaded with brown, edged with dark brown; subterminal line thick, pale yellow; fringe chequered pale yellow and brown. Hindwing pale brown. Forelegs brown. Midlegs with femur brown; tibia brown, inwardly pale yellow; tarsi bronze. Hindlegs with femur brown; tibia pale yellow, speckled with brown; tarsi bronze, speckled with brown.

Abdomen. Male sternum A8 posterior margin broadly indented, with short, rounded lateral projections.

Male genitalia (N = 4) (Fig. 51). Uncus broad, gently narrowing on distal half, apex obtuse. Gnathos projection ca. 2/3 of uncus length, narrow at base, widening toward apex, apex spatula-shaped. Valva ventral margin straight, gently bent dorsad on distal 1/3, dorsal margin convex, apex rounded or slightly pointed. Juxta slender, base roughly quadrangular, apex slightly incurved. Saccus small, pointing dorsad. Phallus with elongated cornutus, at posterior end with narrow bump pointing dorsad.

Female genitalia (N = 5) (Fig. 92). Anterior apophyses with tip or bump at posterior 1/3. Antrum sclerotisation ca. twice as long as broad. Ductus bursae long, slender, with one loop, curved before corpus bursae. Corpus bursae conspicuously pear-shaped, reticulated, with sclerotisation between thorn and corpus opening and faintly marked sclerotised band medially. Thorn long, slightly curved, with small dents pointing toward thorn apex.

Distribution

Known from the slopes of Mount Kinabalu and Mount Monkobo on Borneo, from altitudes between 975 m and 1,850 m.

DNA barcoding

Two MOTUs diverging by 1.7–2.2% are recovered in H. kinabaluensis sp. nov. These two lineages are found in sympatry at Mount Kinabalu.

Etymology

The species name kinabaluensis refers to Mount Kinabalu on Borneo, where the species occurs.

Remarks

The two barcode lineages show no differences in wing pattern and female genitalia. Only minor differences are found in male genitalia, with the apex of the gnathos projection slightly narrower and the basal margin of the juxta slightly incurved in the second lineage. Since second MOTU is only represented by three specimens including only one male, further investigations with a greater number of specimens is needed.

Diagnosis

The forewing markings of H. pangrangoensis sp. nov. are reduced to a small crescent-shaped median discoidal stigma; median cubital and dorsal patches are not marked, and postmedian patch is reduced to a blotch at costa. In male genitalia, the uncus is medially widened and the gnathos shows a finger-like projection ca. half the length of uncus. In female genitalia, the thin longitudinal sclerotised lines of the antrum are unique to this species.

In female genitalia, the long, wrinkled and multicoiled ductus bursae, the ovoid corpus bursae bearing long acanthae, and the long glabrous thorn unequivocally segregates H. ocellata from other Hoploscopa species. Male unknown.

Diagnosis

The forewings of H. astrapias display a median cubital triangular white patch and a bean-shaped postmedian patch red with yellow edges, distally with thick white streak. In male genitalia, the uncus is slender, elongated, the gnathos is reduced to a ring without posterior projection and the valva is slender, with an evenly rounded apex. In female genitalia, the corpus bursae is large, spherical, and bears a large, straight, glabrous thorn.

Similar species

Hoploscopa anamesa, H. nauticorum but the latter can be separated from H. astrapias and H. anamesa based on the forewing: median markings form an elongated white streak running down to dorsal area, disrupted at veins (forming roughly triangular white patch not extending beyond CuA2 in the two other species), and the postmedian patch is quadrangular. In male genitalia, the bristles at uncus apex observed in H. nauticorum are absent or reduced in H. astrapias and H. anamesa, and the valva dorsal margin is strongly produced dorsad on basal half, with a more pointed apex in H. nauticorum (dorsal margin slightly convex in two other species, apex evenly rounded). Forewing and male genitalia of H. astrapias and H. anamesa do not provide unambiguous diagnostic characters to separate them. Median cubital patch of H. anamesa is slightly thicker than that of H. astrapias in specimens examined. Female genitalia allow clear segregation of these two species: antrum is membranous in H. anamesa, while it is lightly sclerotised, twice as long as broad in H. astrapias, and ductus bursae is long, gently coiled twice in H. anamesa, while it is short and broadly curved in H. astrapias.

Description

Head. Antennae dorsally with brown scales. Proboscis white to pale yellow. Maxillary palpi brown, base and inner side pale brown. Labial palpi brown, ventro-basally pale yellow to white.

Thorax (Fig. 27). Collar white. Forewing length: 10–11 mm (♂ & ♀); forewing ground colour brown; basal yellow streak along 1A+2A, abutted with cubital reddish brown fascia running up to median area, disrupted by median cubital patch; costal field reddish brown; median discoidal stigma trapezoid, reddish brown, edged basally and distally with yellow, median cubital patch triangular, snow white, together with median discoidal stigma forming a canine tooth shape; post-median patch bean-shaped, reddish brown with yellow edges, with thick snow white streak abutting dorsally; postmedian area suffused with reddish brown; subterminal line white, not reaching dorsum; subterminal field broadly marked with reddish brown; fringes brown. Hindwing pale yellow, bronze toward distal margin. Forelegs brown. Midlegs brown to bronze; tibia medially white. Hindlegs brown to bronze, tibia base dorsally pale yellow.

Male genitalia (N = 1) (Fig. 68). Uncus long, slender, with straight lateral margin, apex narrow, tongue-shaped, dorsally with sclerotised bristles. Gnathos projection limited to small ridge. Valva slender, ventral margin nearly straight, dorsal margin slightly convex, apex rounded. Juxta broad, with base rounded, apex weakly sclerotised, slightly incurved. Saccus small, pointing dorsad. Phallus with large flat spatula-shaped cornutus.

Female genitalia (N = 1) (Fig. 107). Anterior apophyses with dorsal bump at posterior 1/3. Antrum lightly sclerotised, twice as long as broad. Ductus bursae of medium length, broadly curved. Corpus bursae globular, with posterior half reticulated, anterior half membranous, with weak sclerotisation between thorn and corpus opening. Thorn long and slender, straight, glabrous.

Distribution

Known from the island of Viti Levu (Fiji), at altitudes between 0 and 800 m.

DNA barcoding

Hoploscopa astrapias shows a divergence of 3.9% with H. anamesa and 3.3–4.7% with H. nauticorum.

Phylogenetic relationships

Hoploscopa astrapias, H. anamesa, and H. nauticorum are recovered together in the ML analysis of the COI barcode (BS = 61). This topology is congruent with the morphology of these three species: the forewings display a snow white transversal median line and postmedian streak; in male genitalia, the uncus is elongated, slender, the gnathos is reduced to a sclerotised band without posterior projection, the phallus bears a large, flattened, spatula-shaped cornutus; in female genitalia, the corpus bursae is globular and bears a long and slender straight thorn. Within this clade, a close relationship between H. astrapias and H. anamesa is supported by both morphology and molecular data (BS = 78).

Royal Entomological Society of London, Project Wallace (NHMUK).

Diagnosis

Hoploscopa kelama sp. nov. displays basal and distal discoidal dark brown spots edged with pale yellow, as well as a pale yellow cubital double line on the forewing. In female genitalia, the very small thorn located at the corpus bursae opening is unique to this species.

Similar species

Hoploscopa boleta sp. nov., H. pseudometacrossa sp. nov. Both species display light brown median discoidal stigma and postmedian patch and lack the double pale yellow cubital line observed in H. kelama sp. nov. Examination of genitalia allows unambiguous separation of these species from H. kelama sp. nov.: male genitalia of both species show a slender uncus bearing thick setae, ventrally marked with three small ridges, and female genitalia show a larger thorn located on posterior half of corpus bursae.

Description

Head. Antennae dorsally striped with brown and ochreous scales. Proboscis brown. Maxillary palpi brown, basally pale yellow, inner side pale brown. Labial palpi brown, ventro-basally pale yellow.

Thorax (Fig. 33). Collar white. Forewing length: 8–9.5 mm (♂ & ♀); forewing ground colour brown to dark brown; basal dash black at base, distally pale yellow; basal discoidal patch crescent-shaped, pale yellow, filled with dark brown; distal discoidal patch dark brown, quadrangular, with basal and distal edges pale yellow; double cubital line running from median area distally to tornus, pale yellow; postmedian costal blotch small, pale yellow; subterminal line pale yellow, barely or not marked on its middle fringes brown, with pale yellow dots. Hindwing pale brown. Forelegs brown. Mid- and hindlegs with femur brown; tibia dark brown, distally pale yellow; tarsi brown.

Abdomen. Male sternum A8 posterior margin notched, with short, rounded lateral projections.

Male genitalia (N = 1) (Fig. 72). Uncus long and slender, medially slightly widened, conspicuously narrowed at apical 1/4, apex duck beak-shaped, with small median bump. Gnathos projection limited to a small ridge. Valva ventral margin nearly straight, dorsal margin slightly convex, apex pointed. Juxta slender, with base slightly quadrangular, medially narrowed, apex broadly incurved, weakly sclerotised. Saccus quadrangular.

Female genitalia (N = 3) (Fig. 112). Anterior apophyses with small dorsal bump at posterior 1/3. Antrum sclerotisation broad, ca. twice as long as broad. Ductus bursae long, broad, looped once, bent at corpus opening. Corpus bursae with posterior half reticulated, anterior half membranous. Thorn located on ductus bursae shortly ahead of corpus opening, very small, with dents pointing toward thorn apex.

Distribution

Known from North Sulawesi (Indonesia) at altitudes between 1,000 m and 1,200 m.

Phylogenetic relationships

The ML analysis of the COI barcode recovered H. kelama sp. nov. in a clade with H. albomaculata sp. nov. and H. ignitamaculae sp. nov., but without significant support (BS = 30). These three species vary greatly in their wing pattern but show similarities in the morphology of the genitalia: the uncus apex is duck-shaped, with a small tip on its middle in male genitalia; in female genitalia, the ductus bursae is long and broad, the corpus bursae is globular, with an elongated, well-marked sclerotisation. Hoploscopa kelama sp. nov. and H. ignitamaculae sp. nov. share a small-sized thorn on corpus bursae. Hoploscopa anacantha sp. nov. shares a wing pattern similar to that of H. albomaculata sp. nov., and displays an elongated, marked sclerotisation like in the other three species above, although without thorn.

Etymology

The species epithet kelama comes from the Indonesian “kelam” meaning dark, referring to the dark patterns of the forewing.

Diagnosis

The forewings of H. ignitamaculae sp. nov. display marked basal, median and postmedian reddish orange markings edged with yellow; postmedian patch with undulated basal margin. In male genitalia, the uncus is medially widened, its apex is duck-shaped, ventrally with small bump, and the gnathos is projected into a short, pointed tip. In female genitalia, the well-defined elongated sclerotisation of the corpus bursae with the small slightly curved thorn on its middle is unique to this species.

Similar species

Hoploscopa isarogensis sp. nov. Forewing markings of H. isarogensis sp. nov. tend more to red. Postmedian patch is triangular with a straight basal margin, and subterminal line is often markedly pale yellow. Examination of genitalia allow unambiguous separation of these species.

Valva ventral margin nearly straight, dorsal margin convex, apex pointed. Juxta with rounded base, narrowing on basal half, apex blunt. Saccus slightly quadrangular.

Female genitalia (N = 2) (Fig. 113). Anterior apophyses with dorsal bump at posterior 1/3. Antrum sclerotisation short, as long as wide. Ductus bursae of medium length, broad, bent at anterior and posterior 1/4. Corpus bursae globular, posterior half reticulated, anterior half with erected papillae, with elongated sclerotised area running from corpus opening to its middle. Thorn on middle of sclerotisation, very small, slightly curved, with dents pointing toward thorn base.

Distribution

Known from North Sulawesi (Indonesia) at altitudes between 300 m and 1,150 m.

Phylogenetic relationships

See H. kelama sp. nov.

Etymology

From the Latin ignitus, set on fire, and macula, spot or blot, in reference to the red and yellow spots of the forewing.

Remarks

Specimen MTD8238 shows a forewing pattern resembling that of H. ignitamaculae sp. nov., but with markings reduced. However, the thorn is absent in female genitalia.

DNA barcoding

Two MOTUs are found in morphologically identical specimens from the same locality. The K2P-distance between the two MOTUs is 4.1–6%. The first MOTU, which is the one of the type material, shows an intraspecific variation of 0.7%. The second MOTU is found in three females (samples BC MTD LEP01422, MTD8258 and MTD8261) and shows an intraspecific divergence of 0.6%.

Etymology

Named after the island of Sumatra where the species is encountered.

Remarks

Future examination of male specimens from the second lineage will help to determine whether or not it represents a separate species.

Diagnosis

The forewings of H. mallyi sp. nov. display pale yellow crescent-shaped median discoidal stigma filled with red, together with median cubital patch forming a Y. In male genitalia, the gnathos projection is long, slender, reaching circa 2/3 of the uncus length, and the juxta is ogive-shaped, with a slightly indented apex. In female genitalia, the ductus bursae is long, broad, curved twice, and the corpus bursae is small, globular, with one short curved thorn.

Similar species

Hoploscopa agtuuganonensis sp. nov., H. gracilis sp. nov. In H. agtuuganonensis sp. nov., median discoidal stigma together with cubital and dorsal patches forms a band progressively narrowing toward dorsum (median cubital patch reduced to small streak, median dorsal patch absent in H. mallyi sp. nov.). Hoploscopa gracilis sp. nov. displays wing pattern similar to H. mallyi sp. nov. and can be best separated by examination of genitalia: the uncus and valva are slenderer, the valva apex is pointed (rounded in H. mallyi sp. nov.) and the juxta displays a broad duck beak-shaped apex. In female genitalia of H. gracilis sp. nov., the ductus bursae shows a narrow loop at posterior 1/3, and the thorn is less curved.

Male genitalia (N = 2) (Fig. 76). Uncus slender, medially narrowed, apex spatulate. Gnathos projection slender, ca. 2/3 of uncus length, apex blunt. Valva ventral margin gently bent dorsad on distal 1/3, dorsal margin convex, apex rounded. Juxta ogival, with base quadrangular, gently narrowing toward apex, apex narrow, notched. Saccus triangular, pointing dorsad.

Female genitalia (N = 3) (Fig. 116). Anterior apophyses with dorsal bump at posterior 1/3. Antrum sclerotisation forming a short ring. Ductus bursae long, broad, forming two large curves. Corpus bursae small, globular, reticulate, sclerotised between thorn and corpus opening, medially with broad faintly sclerotised band. Thorn sabre-like, curved, with small dents pointing toward thorn base, basally with conspicuous outwardly projected extension.

Distribution

Known from the slopes of Mount Kinabalu on Borneo, at altitudes between 1,600 m and 2,000 m.

Phylogenetic relationships

This species is recovered in a clade with H. agtuuganonensis sp. nov. and H. gracilis sp. nov. in the ML analysis of the COI barcode (BS = 92). The morphology of these species is in agreement with the molecular findings: in male genitalia, gnathos projection is long and slender; in female genitalia, the antrum sclerotisation is short, the ductus bursae is relatively broad, looped or with conspicuous curves, and the corpus bursae is small, globular.

Etymology

This species is dedicated to our colleague and friend Richard Mally, an eminent lepidopterologist.

Thorn straight, with small dents pointing toward thorn base, basally with small outwardly projected extension.

Distribution

Known from Mount Hagen in the Morobe Province (Papua New Guinea), at an altitude of 1,600 m.

Phylogenetic relationships

The hindwing scent scales observed in males of H. jubata sp. nov., H. pseudometacrossa sp. nov., and H. metacrossa suggest a close relationship between these three species.

Etymology

The name is made by the apposition of the prefix pseudo- from the Greek pseudes, false and metacrossa, referring to the resemblance of this species with H. metacrossa.

Diagnosis

The forewings of H. metacrossa display Y-shaped median and a postmedian pale yellow patches observed in several other Hoploscopa species (e.g., H. danaoensis sp. nov.). Male hindwing displays an androconial organ on the dorsum. The strongly sclerotised tympanic drum in tympanal organs of males is only observed in this species. In male genitalia, gnathos is projected into a small, slender, tongue-shaped tip, and valva is broad, with a rounded ventral margin. In female genitalia, antrum sclerotisation is as long as wide, ductus bursae is short, straight and the corpus bursae is large.

Similar species

Hoploscopa brunnealis, H. danaoensis sp. nov., H. kinabaluensis sp. nov. (q.v.), H. pseudometacrossa sp. nov. (q.v.). Males of H. metacrossa are easily separated from similar species (except H. pseudometacrossa sp. nov.) by the presence of scent organs on the hindwing, the sclerotised tympanic drum, and the characteristic spatulate uncus apex with ventral ridges. Female genitalia of the four above-mentioned species are similar, but ductus bursae is bent before corpus bursae in these species (nearly straight in H. metacrossa) and corpus bursae are smaller than that of H. metacrossa.

This species shows a strong sexual dimorphism. In males, median and postmedian markings are white, and postmedian area is broadly suffused with white. In females, basal patch, median discoidal stigma and postmedian patch are reddish orange, and subterminal area is orange. Male hindwing displays an androconial organ on the dorsum. In male genitalia, gnathos projection is slender, ca. 1/3 of the uncus length, and juxta displays two conspicuous lateral projections at base, and a deeply indented apex. In female genitalia, the four loops formed by the ductus bursae is unique to this species.

Misplaced species

Hoploscopa mediobrunnea (De Joannis, 1929) from Vietnam has been provisionally placed in Hoploscopa by Nuss (1998). He justified his choice as follows: ““Since Eudorina Snellen is a homonym of Eudorina Ehrenberg, 1832 (Protozoa), I place E. mediobrunnea here preliminarily in Hoploscopa. With the white discocellular stigma and the white fasciata adjacent to the median space, the wing pattern of this species look similar to the Musotiminae genus Uthinia. In contrast to Uthinia, H. mediobrunnea shows porrect labial palpi, a long ductus bursae, and the ductus seminalis originates near the antrum. The corpus bursae shows three round signa, with inwardly directed tiny spines arising from their edges.” (Nuss 1998). Its wing shape and the female genitalia are different from all Hoploscopa species we have examined to date, and we therefore assume that H. mediobrunnea belongs to a different genus.

Discussion

Our iterative taxonomic revision resulted in the discovery and description of 26 new species as well as the redescription of 15 species. Thirty of 38 morphospecies were concordant with species delimitation based on the COI barcode. Distinct genetic divergence (i.e., more than 2%) among populations of different islands, with minor morphological differences in wing pattern or male genitalia, suggests reproductive isolation through allopatric effects. In H. matheae sp. nov. and H. parvimacula sp. nov., specimens from Borneo and from Malaysia Peninsula form two distinct MOTUs that deserve closer examination. Cryptic divergence between Borneo and Malayan Peninsula has been found in other studies, e.g., ants (Quek et al. 2007, Feldhaar et al. 2010), bats (Francis et al. 2010), and birds (Lohman et al. 2011). Similarly, specimens of H. danaoensis sp. nov. and H. isarogensis sp. nov. from different Philippines islands display distinct genetic differentiation suggesting allopatric differentiation. Cryptic diversity among populations of different Philippines islands has also been reported in birds (Lohman et al. 2010). We found specimens from Eastern New Guinea resembling the type specimens of H. quadripuncta and H. semifascia from Western New Guinea, but displaying minor differences in male genitalia in each case. This suggests potential east-west differentiation along the Cordillera, as observed in birds (Joseph et al. 2001). Molecular investigations of specimens from Western New Guinea should be performed to test this hypothesis. High DNA barcode divergence in geographically distant species reveals the need for a better sampling with higher geographical coverage to investigate both intraspecific and interspecific variation (Bergsten et al. 2012, Talavera et al. 2013).

Two cases of high genetic divergence found in sympatric populations deserve closer attention. The first case involves H. sumatrensis sp. nov. from north Sumatra, where two mitochondrial lineages differ by 4.1–6%. In the second case, a divergence of 1.7–2.2% is observed in sympatric specimens of H. kinabaluensis sp. nov. on Mount Kinabalu. Closer examination of the morphology did not reveal any differences in either case. Inclusion of nuclear markers is needed in order to test if these mitochondrial lineages reflect different species or cases of introgression, symbiont infection, or maternal lineage sorting (Funk and Omland 2003, Hurst and Jiggins 2005, Harrison and Larson 2014). Notably, introgression has been reported in Lepidoptera (Zakharov et al. 2009; Cong et al. 2017), including Crambidae (Mally et al. 2018).

The investigated material more than doubled the number of Hoploscopa species. With 41 species now described, we still have not reached the saturation phase in species discovery for this group. For example, morphology of the female genitalia and molecular data support specimens MTD8238 and MTD8243 as different species, for which male specimens remain to be discovered. Similarly, molecular data and images of the habitus support specimen USNM_ENT_00739239 as a new but yet undescribed species. Unfortunately, this specimen could not be located (Scott Miller, pers. comm.). Additionally, the nine cases of morphospecies split into two or more MOTUs suggest putative new cryptic species and require further examination. In the NHMUK collection, we estimate at least a further 30 species await description. The presumed sister-group Perimeceta is probably less diverse, with four described species to date and an estimated twelve undescribed species in the collections of the NHMUK.

Hoploscopa is predominantly found in montane wet forests of South-East Asia at altitudes above 1,000 m, while species from higher latitudes tend to stretch their altitudinal distribution down to the lowlands, e.g., on the Philippines (H. danaoensis sp. nov., H. isarogensis sp. nov.) and the Melanesian islands (H. astrapias, H. anamesa, H. nauticorum). Mountain of South-East Asia are also home to other species-rich crambid groups, e.g., Glaucocharis, Micraglossa, and Scoparia (Gaskin 1985, Nuss 1998). Based on our data, we hypothesise isolation through elevation, higher specialisation, and seasonality as three potential factors driving the diversification of Hoploscopa. Isolation through elevation promotes species diversity and endemism (Steinbauer et al. 2016). The study of Merckx et al. (2015) on a broad range of taxonomic groups from Mount Kinabalu suggested endemic species on tropical mountains to originate either from long-distance dispersal (eccentric species) or from colonisation from local lowlands (centric species). All seven new species from Mount Kinabalu described in this paper do not share morphological similarities and no close relationships was recovered among them. On the contrary, H. mallyi sp. nov. from Mt Kinabalu forms a well-supported clade with H. agtuuganonensis sp. nov. from Mindanao and H. gracilis sp. nov. from Sumatra and represents a possible case of long-distance dispersal across islands. Colonisation from local lowland is also conceivable in Hoploscopa: H. cynodonta sp. nov. is reported at an altitude of 300 m in Brunei, and other Hoploscopa specimens have been collected at altitudes of 500 m at the foot of Mount Kinabalu (Schulze 2000). Secondly, on-site specialisation on host plant is another possible driver of speciation. Moths were shown to be high specialists in tropical mountains (Rodríguez-Castañeda et al. 2010). Larvae of Hoploscopa feed on ferns, which show a high species diversity in montane wet forests of South-East Asia (Ebihara and Kuo 2012). Current host plant records report five Hoploscopa species to feed on ferns belonging to three distinct genera (Miller et al. 2015; Mally et al. 2017). Ferns are scarcely used by Lepidoptera (Weintraub et al. 1995) and thus represent a large palette of potential larval food. Finally, there is a possible seasonality occurring in Hoploscopa species. The Hoploscopa larva described by Mally et al. (2017) and collected during a field trip on Mount Kinabalu did not match any of the eight species we collected there, although we cannot rule out the possibility that we simply did not collect it. Seasonality is observed in Pyraloidea from lowlands surrounding Mount Kinabalu (Schulze and Fiedler 2003) but no studies are available on the seasonality of moths at higher elevations in South-East Asia. Further systematic work on Hoploscopa, phylogeographic investigations, as well as accumulation of host plant records will assist in completing a more comprehensive picture of its diversity.
