Part II: parvorder Hadziidira https://zookeys.pensoft.net/article/116721/ ZooKeys 1195: 249-296

DOI: 10.3897/zookeys.1195.116721

Authors: Kristine N. White, Sally J. Sir

Abstract: Amphipods in the parvorder Hadziidira are typically associated with algae, sponges, or coral rubble. Members of the parvorder have a gnathopod 2 that is stouter than gnathopod 1, a pair of dorsal robust setae on urosomite 2, and a basofacial robust seta on the uropod 1 peduncle. Within the parvorder, six families are documented from Bocas del Toro, Panama, represented by 26 species. This research documents range extensions for all 26 species and an identification key to the species of Caribbean Hadziidira of Panama is provided.

Seven new species of Tetranemertes Chernyshev, 1992 (Monostilifera, Hoplonemertea, Nemertea) from the Caribbean Sea, western Pacific, and Arabian Sea, and revision of the genus https://zookeys.pensoft.net/article/109521/ ZooKeys 1181: 167-200

DOI: 10.3897/zookeys.1181.109521

Authors: Irina Cherneva, Christina I. Ellison, Eduardo E. Zattara, Jon L. Norenburg, Megan L. Schwartz, Juan Junoy, Svetlana A. Maslakova

Abstract: The marine ribbon worm genus Tetranemertes Chernyshev, 1992 currently includes three species: the type species T. antonina (Quatrefages, 1846) from the Mediterranean Sea, T. rubrolineata (Kirsteuer, 1965) from Madagascar, and T. hermaphroditica (Gibson, 1982) from Australia. Seven new species are described: T. bifrost sp. nov., T. ocelata sp. nov., T. majinbuui sp. nov., and T. pastafariensis sp. nov. from the Caribbean Sea (Panamá), and three species, T. unistriata sp. nov., T. paulayi sp. nov., and T. arabica sp. nov., from the Indo-West Pacific (Japan and Oman). As a result, an amended morphological diagnosis of the genus is offered. To improve nomenclatural stability, a neotype of Tetranemertes antonina is designated from the Mediterranean. The newly described species, each characterized by features of external appearance and stylet apparatus, as well as by DNA-barcodes, form a well-supported clade with T. antonina on a molecular phylogeny of monostiliferan hoplonemerteans based on partial sequences of COI, 16S rRNA, 18S rRNA, and 28S rRNA. Six of the seven newly described species, as well as T. rubrolineata, possess the unusual character of having a central stylet basis slightly bilobed to deeply forked posteriorly in fully grown individuals, a possible morphological synapomorphy of the genus. In addition, an undescribed species of Tetranemertes is reported from the Eastern Tropical Pacific (Panamá), increasing the total number of known species in the genus to eleven.

Caribbean Amphipoda (Crustacea) of Panama. Part I: parvorder Oedicerotidira https://zookeys.pensoft.net/article/102034/ ZooKeys 1159: 37-50

DOI: 10.3897/zookeys.1159.102034

Authors: Elizabeth L. Durham, Kristine N. White

Abstract: Amphipods in the parvorder Oedicerotidira are burrowers, furrowers, or surface skimmers. Members of the parvorder share a well-developed posteroventral lobe on coxa 4, an equilobate coxa 5, an immensely elongate pereopod 7 that differs in structure from pereopod 6, and an entire telson. Within the parvorder, only the family Oedicerotidae has been documented from Bocas del Toro, Panama, represented by two species. This research documents a range extension for Hartmanodes nyei (Shoemaker, 1933) and describes a new species of Synchelidium Sars, 1892. An identification key to the species of Caribbean Oedicerotidae of Panama is provided.

A new species of Dipsas (Serpentes, Dipsadidae) from central Panama https://zookeys.pensoft.net/article/96616/ ZooKeys 1145: 131-167

DOI: 10.3897/zookeys.1145.96616

Authors: Julie M. Ray, Paola Sánchez-Martínez, Abel Batista, Daniel G. Mulcahy, Coleman M. Sheehy III, Eric N. Smith, R. Alexander Pyron, Alejandro Arteaga

Abstract: A new species of Dipsas Laurenti, 1768, from Central Panama is described based on molecular analyses, hemipenial morphology, and external characters. This is the sixth species of Dipsas to be described for the country; the snake has been suspected to exist since 1977 and has not been thoroughly studied until now. Additionally, morphological comparations including scale counts are done with other species within the genus, and the current geographic distribution of Dipsas temporalis (Werner, 1909), the sister species, is updated. Finally, a key to the species of Dipsas currently known from Middle America is presented.

The Trichoptera of Panama. XIX. Additions to and a review of the genus Leucotrichia (Trichoptera, Hydroptilidae) in Panama https://zookeys.pensoft.net/article/77371/ ZooKeys 1111: 425-466

DOI: 10.3897/zookeys.1111.77371

Authors: Robin E. Thomson, Brian J. Armitage, Steven C. Harris

Abstract: Prior to 2016, three species of caddisflies in the genus Leucotrichia (Trichoptera: Hydroptilidae) were known from Panama. Subsequently, one new species and four new country records were added to Panama’s fauna. Herein, four new species are described (Leucotrichia cortadera sp. nov., L. holzenthali sp. nov., L. luma sp. nov., L. ruiteri sp. nov.) and two new country records added for Panama (L. botosaneanui Flint, 1996, L. hispida Thomson & Holzenthal, 2015). The resulting total of 14 species makes Panama the most species-rich country for this genus. Panama’s species assemblage is most similar to Costa Rica and Mexico. However, the similarities among faunas in all these countries is very low (< 35%). Thus, more new country records are possible with additional collecting. Recent collections (2015–2021) of new caddisfly species and country records in this genus were effected primarily by use of Malaise traps. Our collections also evidenced multiple species from the same collecting site, with seven species each found in both lowland and mid-altitude sites. Investigation of the distribution of Leucotrichia species with altitude reveals a preference by several species for higher altitude locations. Additional Malaise trap collections over extended time periods are needed to verify the validity of all observations and preliminary conclusions made to date.

A new rainfrog of the genus Pristimantis (Anura, Brachycephaloidea) from central and eastern Panama https://zookeys.pensoft.net/article/63009/ ZooKeys 1081: 1-34

DOI: 10.3897/zookeys.1081.63009

Authors: Konrad Mebert, Macario González-Pinzón, Madian Miranda, Edgardo Griffith, Milan Vesely, P. Lennart Schmid, Abel Batista

Abstract: Substantial molecular and morphological character differences lead us to the description of a new species of the genus Pristimantis from the cloud forest of Cerro Chucantí, Maje Mountains, Darien Province, as well as from several other mountain ranges in eastern and central Panama. Pristimantis gretathunbergae sp. nov. is a sister species to the allopatric P. erythropleura-penelopus group from northern Colombia with a mtDNA sequence divergence of > 4.4% at 16S and > 14.6% at COI. Its closest congener in sympatry is P. cruentus that differs by a large sequence divergence of > 9.6% in 16S mtDNA and 19.0% at COI, and from which it differs also by ventral and groin coloration, unusually prominent black eyes, a contrasting light upper lip, commonly a single conical to spine-like tubercle on the upper eyelid, and a larger head. While the habitat continuity at most sites in eastern Panama is moderate, habitats in central Panama are severely fragmented. Cerro Chucantí and the surrounding Maje Mountains are highly threatened by rapid deforestation and replaced by plantations and cattle pastures. Thus, investigations on the ecology of the new species and its population status, especially at the type locality, are highly recommended. As a flagship species, this new frog can help to preserve the Chucantí cloud forest including several recently described species known only from this isolated area in eastern Panama.

Designation of the neotype of Triatoma dimidiata (Latreille, 1811) (Hemiptera, Reduviidae, Triatominae), with full integrated redescription including mitogenome and nuclear ITS-2 sequences https://zookeys.pensoft.net/article/72835/ ZooKeys 1076: 9-24

DOI: 10.3897/zookeys.1076.72835

Authors: Silvia Andrade Justi, Carolina Dale

Abstract: The taxonomic status of Triatoma dimidiata (Latreille, 1811) is, by far, the most discussed within Triatominae. Molecular studies have recovered at least three independently evolving lineages in T. dimidiata across its range. The original description of T. dimidiata (as Reduvius dimidiatus) included few taxonomic characters, and no types were assigned. To define and describe the cryptic diversity within T. dimidiata sensu lato (s.l.), a neotype must be designated. For this purpose, all 199 specimens identified as T. dimidiata from the collections of the Smithsonian Institution – National Museum of Natural History and the American Museum of Natural History, ranging from Peru to Mexico, were studied. Only one specimen (from Tumbes, Peru) matched the combination of characters as listed in the original description, and it is herein formally designated as the neotype for T. dimidiata. The neotype is morphologically described and DNA sequences of its whole mitochondrial genome and the nuclear second internal transcribed spacer region (ITS2), commonly used in triatomine molecular systematics studies, are presented and compared to other publicly available sequences of T. dimidiata s.l. in GenBank. Our results suggest that T. dimidiata sensu stricto (s.s.) is somewhat rare and, therefore, unlikely to serve as a major vector of Chagas disease.

Amphibian diversity in Serranía de Majé, an isolated mountain range in eastern Panamá https://zookeys.pensoft.net/article/32869/ ZooKeys 859: 117-130

DOI: 10.3897/zookeys.859.32869

Authors: Daniel Medina, Roberto Ibáñez, Karen R. Lips, Andrew J. Crawford

Abstract: Eastern Panamá is within the Mesoamerican biodiversity hotspot and supports an understudied amphibian fauna. Here we characterize the amphibian diversity across an elevational gradient in one of the least studied mountain ranges in eastern Panamá, Serranía de Majé. A total of 38 species were found, which represent 17% of all species reported for Panamá. Based on expected richness function and individual-based rarefaction curves, it is estimated that this is an underestimate and that at least 44 amphibian species occur in this area. Members of all three amphibian orders were encountered, represented by ten families and 22 genera, including five species endemic to Central America. Estimated species richness decreased with elevation, and the mid-elevation site supported both lowland and highland species. Our study provides a baseline for understanding the distribution pattern of amphibians in Panamá, for conservation efforts, and for determining disease-induced changes in amphibian communities.

A geographic distribution database of the Neotropical cassava whitefly complex (Hemiptera, Aleyrodidae) and their associated parasitoids and hyperparasitoids (Hymenoptera) https://zookeys.pensoft.net/article/6193/ ZooKeys 545: 75-87

DOI: 10.3897/zookeys.545.6193

Authors: Aymer Andrés Vásquez-Ordóñez, Nicolas А. Hazzi, David Escobar-Prieto, Dario Paz-Jojoa, Soroush Parsa

Abstract: Whiteflies (Hemiptera, Aleyrodidae) are represented by more than 1,500 herbivorous species around the world. Some of them are notorious pests of cassava (Manihot esculenta), a primary food crop in the tropics. Particularly destructive is a complex of Neotropical cassava whiteflies whose distribution remains restricted to their native range. Despite their importance, neither their distribution, nor that of their associated parasitoids, is well documented. This paper therefore reports observational and specimen-based occurrence records of Neotropical cassava whiteflies and their associated parasitoids and hyperparasitoids. The dataset consists of 1,311 distribution records documented by the International Center for Tropical Agriculture (CIAT) between 1975 and 2012. The specimens are held at CIAT’s Arthropod Reference Collection (CIATARC, Cali, Colombia). Eleven species of whiteflies, 14 species of parasitoids and one species of hyperparasitoids are reported. Approximately 66% of the whitefly records belong to Aleurotrachelus socialis and 16% to Bemisia tuberculata. The parasitoids with most records are Encarsia hispida, Amitus macgowni and E. bellottii for A. socialis; and E. sophia for B. tuberculata. The complete dataset is available in Darwin Core Archive format via the Global Biodiversity Information Facility (GBIF).

Systematics of the Rhinella margaritifera complex (Anura, Bufonidae) from western Ecuador and Panama with insights in the biogeography of Rhinella alata https://zookeys.pensoft.net/article/5214/ ZooKeys 501: 109-145

DOI: 10.3897/zookeys.501.8604

Authors: Sueny P. dos Santos, Roberto Ibáñez, Santiago R. Ron

Abstract: The Rhinella margaritifera species group consists of 17 species of toads distributed in tropical and subtropical South America and eastern Central America. The identity of some of its species is poorly understood and there are numerous undescribed cryptic species. Among them, the status of Rhinella margaritifera is one of the most problematic. Its range includes lowland rainforests separated by the Andes, the Chocoan rainforest to the west and the Amazonian rainforest to the east. This distribution is puzzling because the Andes are an old and formidable barrier to gene flow and therefore should generate vicariant speciation between disjunct lowland populations. Herein we clarify the taxonomy of populations of the R. margaritifera complex from Central America and the Chocó region of South America. The morphological and genetic variation of R. margaritifera was examined from 39 populations from Chocó, 24 from the upper Amazon region of Ecuador, and 37 from Panama, including the holotype of the Panamanian R. alata. Phylogenetic analyses were performed based on mitochondrial genes 12S rRNA, 16S rRNA, and cytochrome c oxidase I (COI) and the nuclear gene Tyrosinase (Tyr). The genetic and morphological data show that Panamanian and Chocoan populations are conspecific. In the phylogeny, populations from Chocó and Panama form a well-supported clade. The morphology of the holotype of R. alata falls within the variation range of Panamanian and Chocoan populations. Based on all this evidence, we assign the populations from western Ecuador and Panama to R. alata and demonstrate that the unusual distribution pattern of “R. margaritifera” on both sides of the Andes was an artifact of incorrectly defined species boundaries.

Embryo production in the sponge-dwelling snapping shrimp Synalpheus apioceros (Decapoda, Alpheidae) from Bocas del Toro, Panama https://zookeys.pensoft.net/article/4261/ ZooKeys 457: 227-238

DOI: 10.3897/zookeys.457.6403

Authors: Adriana Rebolledo, Ingo Wehrtmann, Darryl Felder, Fernando Mantelatto

Abstract: Caridean shrimps of the genus Synalpheus are abundant and widely distributed in tropical and subtropical regions, but knowledge of their reproductive biology remains scarce. We report reproductive traits of Synalpheus apioceros from Bocas del Toro, Panama, based on collections in August 2011. The 46 ovigerous females that were analyzed ranged in size from 3.8 to 7.4 mm in carapace length. Fecundity varied between 8 and 310 embryos and increased with female size. Females invested 18.6 ± 10.3% of their body weight in Embryo production. Embryo volume increased considerably (77.2%) during embryogenesis, likely representing water uptake near the end of incubation period. Compared to Synalpheus species with abbreviated or direct development, S. apioceros produced substantially smaller embryos; however, S. apioceros seems to have a prolonged larval phase with at least five zoeal stages, which may explain the combination of relatively small and numerous embryos. We did not find nonviable, minute, chalky embryos, previously reported for S. apioceros specimens obtained from the northwestern Gulf of Mexico, which supports the hypothesis that the production of this type of embryos may be a physiological response of this warm-water species to the temperature decrease near to its latitudinal range limit.

A geographic distribution database of Mononychellus mites (Acari, Tetranychidae) on cassava (Manihot esculenta) https://zookeys.pensoft.net/article/3793/ ZooKeys 407: 1-8

DOI: 10.3897/zookeys.407.7564

Authors: Aymer Vásquez-Ordóñez, Soroush Parsa

Abstract: The genus Mononychellus is represented by 28 herbivorous mites. Some of them are notorious pests of cassava (Manihot esculenta Crantz), a primary food crop in the tropics. With the exception of Mononychellus tanajoa (Bondar), their geographic distribution is not widely known. This article therefore reports observational and specimen-based occurrence data of Mononychellus species associated with cassava. The dataset consists of 1,513 distribution records documented by the International Center for Tropical Agriculture (CIAT) between 1975 and 2012. The specimens are held at CIAT’s Arthropod Reference Collection (CIATARC). Most of the records are from the genus’ native range in South America and were documented between 1980 and 2000. Approximately 61% of the records belong to M. tanajoa, 25% to M. caribbeanae (McGregor), 10% to M. mcgregori (Flechtmann and Baker) and 2% to M. planki (McGregor). The complete dataset is available in Darwin Core Archive format via the Global Biodiversity Information Facility (GBIF).

Three new species in the genus Wilkinsonellus (Braconidae, Microgastrinae) from the Neotropics, and the first host record for the genus https://zookeys.pensoft.net/article/3132/ ZooKeys 302: 79-95

DOI: 10.3897/zookeys.302.4962

Authors: Diana Arias, James Whitfield, Daniel Janzen, Winnie Hallwachs

Abstract: The genus Wilkinsonellus Mason is a poorly sampled but widely distributed tropical genus of Microgastrinae (Braconidae), parasitoid wasps that exclusively attack caterpillars (Lepidoptera). Currently, species of Wilkinsonellus have been described only from the Palaeotropics, but the genus was known to occur in the Neotropics. Here we describe the first three species from Central and South America: Wilkinsonellus alexsmithi sp. n., Wilkinsonellus kogui sp. n., and Wilkinsonellus panamaensis sp. n. These species descriptions confirm that Wilkinsonellus is a Pantropical genus. A dichotomous key for the three new Neotropical species is given. The first recorded host for the genus, Microthyris prolongalis (Crambidae), is also reported, for Wilkinsonellus alexsmithi.

Barucynips panamensis, a new genus and species of oak gallwasps (Hymenoptera, Cynipidae, Cynipini) from Panama, and description of one new species of Coffeikokkos https://zookeys.pensoft.net/article/3739/ ZooKeys 277: 25-46

DOI: 10.3897/zookeys.277.3942

Authors: Enrique Medianero, Jose Luis Nieves-Aldrey

Abstract: Barucynips panamensis Medianero & Nieves-Aldrey, a new genus and species of oak gallwasps (Hymenoptera: Cynipidae: Cynipini), is described from adults reared from galls on Quercus bumelioides in Panama. The new genus is taxonomically close to the recently described Coffeikokkos from Costa Rica, but differs from it and all of the described genera of Cynipini, by the shape and setation of the projecting part of the ventral spine of the hypopygium and by the sculpture of the propodeum. A new species of Coffeikokkos is also described from the same area, the Volcán Barú in Panama. Diagnostic characters, gall description, distribution, and biological data of the new genus and the two new species are given. The new genus is the first genus of oak gallwasps of the tribe Cynipini described in Panama.

Serpula and Spiraserpula (Polychaeta, Serpulidae) from the Tropical Western Atlantic and Gulf of Guinea https://zookeys.pensoft.net/article/2835/ ZooKeys 198: 1-23

DOI: 10.3897/zookeys.198.3030

Authors: Rolando Bastida-Zavala

Abstract: Six species of Serpula and Spiraserpula were identified, mainly, from the material of the expeditions of the Rosenstiel School of Marine and Atmospheric Science, University of Miami, including two new species of Serpula. Serpula madrigalae sp. n. from the Turks and Caicos has a tube with five longitudinal ridges, four rows of alveoli and a medium-sized shallow symmetrical opercular funnel with 17 radii, and an inner surface with opercular tubercles. Serpula vossae sp. n. from the Western Caribbean and Bahamas has a tube with 6–8 longitudinal ridges, and a large, deep symmetrical opercular funnel, with 21–33 radii, and a smooth inner surface. Serpula cf. vermicularis, recorded from the Gulf of Guinea (tropical eastern Atlantic), is distinguished from the nominal species in possessing fewer opercular radii (33–39) and the lack of a proximal rasp in the bayonet chaetae; tubes are missing. The distribution range is extended for the three known Spiraserpula species found in the collections, S. caribensis, S. karpatensis and S. ypsilon.

A new golden frog species of the genus Diasporus (Amphibia, Eleutherodactylidae) from the Cordillera Central, western Panama https://zookeys.pensoft.net/article/2807/ ZooKeys 196: 23-46

DOI: 10.3897/zookeys.196.2774

Authors: Andreas Hertz, Frank Hauenschild, Sebastian Lotzkat, Gunther Koehler

Abstract: We describe the frog species Diasporus citrinobapheus sp. n. from the Cordillera Central of western Panama. The new species differs from all other species in its genus in coloration, disk cover and disk pad shape, skin texture, advertisement call, and size. It is most similar to D. tigrillo, from which it differs in dorsal skin texture, relative tibia length, number of vomerine teeth, ventral coloration, dorsal markings, and relative tympanum size, and to D. gularis, from which it can be distinguished by the lack of membranes between the toes, adult size, posterior thigh coloration, and position of the choanae. We provide data on morphology, vocalization, and distribution of the new species, as well as brief information on its natural history.

A revision of the spider genus Selenops (Arachnida, Araneae, Selenopidae) in North America, Central America and the Caribbean https://zookeys.pensoft.net/article/2524/ ZooKeys 105: 1-182

DOI: 10.3897/zookeys.105.724

Authors: Sarah Crews

Abstract: The spider genus Selenops Latreille occurs in both the Old World and New World tropics and subtropics and contains nearly half of the species in the family Selenopidae Simon. In this paper I revise the members of this genus found in North America, Central America, and on islands of the Caribbean, excluding Cuban endemics. Despite recent work in these regions, there is still a great deal of new diversity in the form of undescribed species. In the United States species, there is a great deal of variation among species, and there appears to be overlap of up to three species in a particular locality. Additionally, males and females were described from different localities, adding to the uncertainty surrounding species placement. No taxonomic changes are currently made to the species from the southwestern United States. In total, 21 new species are described including S. arikok sp. n., S. chamela sp. n., S. amona sp. n., S. baweka sp. n., S. bocacanadensis sp. n., S. enriquillo sp. n, S. ixchel sp. n., S. huetocatl sp. n., S. kalinago sp. n., S. oviedo sp. n., S. morro sp. n., S. denia sp. n., S. duan sp. n., S. malinalxochitl sp. n., S. oricuajo sp. n., S. petenajtoy sp. n., S. guerrero sp. n., S. makimaki sp. n., S. souliga sp. n., S. wilmotorum sp. n., and S. wilsoni sp. n. Selenops lunatus Muma is recognized as a junior synonym of S. candidus Muma, S. tehuacanus Muma, S. galapagoensis Banks and S. vagabundus Kraus are recognized as junior synonyms of S. mexicanus Keyserling, S. santibanezi Valdez-Mondragon is recognized as a junior synonym of S. nigromaculatus Keyserling, and S. salvadoranus Chamberlin is recognized as a junior synonym of S. bifurcatus Banks. The males of S. bani Alayon-Garcia and S. marcanoi Alayon-Garcia are described for the first time, and the females of S. phaselus Muma and S. geraldinae Corronca are described for the first time. Almost all species are redescribed, barring Cuban endemics and a few species only recently described, and new illustrations are provided, including those of the internal female genitalia, many of which are illustrated for the first time. A key to species is also provided as are all new distributional records.

Acanthodasys caribbeanensis sp. n., a new species of Thaumastodermatidae (Gastrotricha, Macrodasyida) from Belize and Panama https://zookeys.pensoft.net/article/2366/ ZooKeys 61: 1-10

DOI: 10.3897/zookeys.61.552

Authors: Rick Hochberg, Sarah Atherton

Abstract: We describe one new species of Acanthodasys (Gastrotricha, Macrodasyida, Thaumastodermatidae) collected from sublittoral sites around Carrie Bow Cay, Belize and Isla Colón in the Bocas del Toro archipelago, Panama. Though eight species of Acanthodasys are currently recognized, no species has yet been reported from the Caribbean. Acanthodasys caribbeanensis sp. n. is characterized by the lack of lateral adhesive tubes, the presence of ventrolateral adhesive tubes, and with cuticular armature in the form of both spineless and spined scales. The spineless scales are not elliptical as in other species of Acanthodasys, but are instead variable in shape and closely resemble the spineless scales of species of Diplodasys. Spined scales bear uniancres up to 50 µm long and are the largest reported in the genus. Uniancres are arranged dorsally around the mouth rim and distributed in five distinguishable columns. Adult size varies from 325–625 µm long.

Hystrignathus dearmasi sp. n. (Oxyurida, Hystrignathidae), first record of a nematode parasitizing a Panamanian Passalidae (Insecta, Coleoptera) https://zookeys.pensoft.net/article/2326/ ZooKeys 57: 1-8

DOI: 10.3897/zookeys.57.477

Authors: Jans Rodríguez, Nayla Rodríguez

Abstract: Hystrignathus dearmasi sp. n. (Oxyurida: Hystrignathidae) is described from an unidentified passalid beetle (Coleoptera: Passalidae) from Panama. It resembles Hystrignathus cobbi Travassos & Kloss, 1957 from Brazil, bya similar form of the cephalic end, extension of cervical spines and absence of lateral alae. It differs from the latter species bythe body shorter, the oesophagus and tail comparatively larger, the vulva situated more posterior and the eggs ridged. This species constitutes the first record of a nematode parasitizing a Panamanian passalid.

A new species of Aximopsis sensu lato Ashmead (Hymenoptera, Chalcidoidea, Eurytomidae) parasitic on Euglossa spp. (Hymenoptera, Apidae) https://zookeys.pensoft.net/article/2045/ ZooKeys 20: 165-174

DOI: 10.3897/zookeys.20.137

Authors: Michael Gates

Abstract: Aximopsis masneri Gates, sp. n., (Hymenoptera, Chalcidoidea, Eurytomidae) is described and illustrated. This species was reared from field-collected nests of Euglossa sp. (Hymenoptera, Apidae) in the Neotropical region with additional label data indicating E. variabilis and E. cybelia as hosts. It is compared with the nominate species of the nodularis species group of Aximopsis sensu lato to which it belongs.
