Abstract

Eight new species of Embioptera from Brazil are described, diagnosed, and illustrated. For Anisembiidae: Chelicerca achilata Szumik, Pereyra & Juárez, sp. nov.; Saussurembia borba Szumik, Pereyra & Juárez, sp. nov. For Archembiidae: Archembia oruma Szumik, sp. nov.; Embolyntha oriximina Szumik, Pereyra & Juárez, sp. nov.; Pararhagadochir bonita Szumik, Pereyra & Juárez, sp. nov., Pararhagadochir marielleae Szumik, Pereyra & Juárez, sp. nov.; Pararhagadochir para Szumik, Pereyra & Juárez, sp. nov. For Clothodidae: Chromatoclothoda langa Szumik, Pereyra & Juárez, sp. nov. To clarify the higher classification of the Order and to have an accurate taxonomy, a species catalog and introduction to the four families present in Brazil is also detailed, including phylogenetic relationships, taxonomic actions, composition, distributions, and records maps. Herein, several taxonomic acts are proposed: (1) the synonymy of Chelicerca Ross (= Dactylocerca Ross confirmed junior synonym; = Schizembia Ross syn nov.; = Pelorembia Ross, confirmed junior synonym; = Cryptembia Ross, syn. nov.) and Saussurembia Davis (= Stenembia Ross, syn. nov.). (2) new status and delimitation for family Archembiidae Ross, stat. rev.; subfamily Archembiinae Ross, stat. rev.; subfamily Pachylembiinae stat. rev.; subfamily Scelembiinae stat. rev., and their genera included. (3) Diradius unicolor (Ross) (Teratembiidae) comb. nov., and (4) new locality records for previously cited species in the region.

Introduction

The biodiversity of Brazil harbors the highest number of insect species on Earth, reaching approximately 9% of the total known species, where many of them are endemic taxa (Rafael et al. 2012). However, unfortunately, the knowledge on the real biodiversity of Brazil can only be estimated and remains scant, even in protected areas (see e.g., Rafael et al. 2009; Diniz-Filho et al. 2010; Carvalho 2012; Oliveira et al. 2017). This is also the case of the Order Embioptera whose representativeness of species is very low if we consider the surface and the diversity of biomes present in the country (Rafael et al. 2012; Szumik 2012). Szumik (2012) recorded four of the five families of American embiids for Brazil, i.e., Archembiidae, Anisembiidae, Teratembiidae, and Clothodidae. These families were represented by 21 genera and 41 species, a number of species that should at least be triplicated. In the last years, only six new species were described for Brazil, one clothodid (Krolow and Valadares 2016) and five archembiids (Szumik et al. 2017; Salvatierra 2020; Costa-Pinto et al. 2021). In addition, new records for an archembiid and an anisembiid were reported for two states of Brazil (Teixeira et al. 2018a, b) as well as records of presence of the Order in studies of microhabitat diversity (Lopes Ferreira and Sousa Silva 2001; Sousa Silva et al. 2009).

Here, we describe eight new species from Brazil, most of them from the Amazonian region; we also add new records for previously cited species in the region. The classification used here follows Szumik et al. (2019), which is the most accurate analysis involving the total evidence to date. To have a better understanding of the higher classification of the Order, an introduction to the families present in Brazil is developed. The genera where the new species are included have a section with diagnosis, composition, distribution, and phylogenetic relationships. Finally, for the first time, a complete list of the Brazilian species is presented.

As Carvalho (2012) clearly argued, there are two major problems with Brazilian taxonomic studies: one is the excessive richness species of the country and the other, the reduced number of taxonomists. Hopefully, our observations will encourage young researchers to study the biodiversity of embiids from Brazil.

Materials and methods

The material from the new species described here is deposited at Instituto Nacional de Pesquisas da Amazônia, Manaus, INPA collection, Museum of Zoology of the University of São Paulo, MZUSP collection, and Museum of Comparative Zoology, Harvard University, MCZ collection.

Many of the species known for Brazil were described by E.S. Ross (California Academy of Science) in his last monographs (e.g., Ross 2001, 2003), where the author stated that additional specimens of the described taxa were deposited in Brazilian Institutions like INPA and MZUSP; however, these specimens could not be found at those institutions. All the observations on the Brazilian specimens (e.g., species catalog, new records) are the result of the collection studies from several museums as well as the Ross collection (California Academy of Science).

Results

Family Anisembiidae Davis, 1940

Anisembiidae has an exclusively American distribution, and it is the most diverse group of the Order with 24 genera and more than 100 species assigned at different levels of subfamilies, tribes, or groups of species (Ross 2003). However, Ross’ classification does not have taxonomic and phylogenetic evidence to support it (Szumik 1996; Szumik et al. 2008; Miller et al. 2012), since some of the assignments were erroneously proposed, such as the creation of monotypic genera based on autapomorphic species or the definition of groups of species using geographical division as a criterion (Szumik et al. 2008, 2019). Although the monophyly of the family was supported in several phylogenetic analyses (e.g., Szumik 1996; Szumik et al. 2008; Miller et al. 2012), the inconsistency of some groupings is clear as well as the para/polyphyly of many of the proposed genera (e.g., Pelorembia Ross and Dactylocerca Ross; Szumik et al. 2008: 998). Currently, the family is under review but in this work we list the 19 valid genera, including several synonymies proposed here (see below for details): Anisembia Krauss, 1911; Aporembia Ross, 2003; Brasilembia Ross, 2003; Bulbocerca Ross, 1940; Chelicerca Ross, 1940 (= Cryptembia Ross, 2003; = Dactylocerca, Ross 1940; = Pelorembia Ross, 1984; = Schizembia Ross, 1944); Chorisembia Ross, 2003; Ectyphocerca Ross, 2003; Exochosembia Ross, 2003; Glyphembia Ross, 2003; Isosembia Ross, 2003; Mesembia Ross, 1940; Microembia Ross, 1944; Oncosembia Ross, 2003; Phallosembia Ross, 2003; Platyembia Ross, 2003; Pogonembia Ross, 2003; †Poinarembia Ross, 2003; Saussurembia Davis, 1940 (= Stenembia Ross, 1972); Scolembia Ross, 2003.

In this work, two new species of Anisembiidae are described, the synonymy of various genera is confirmed and, a complete list of known Brazilian species and new locality records are added. Consequently, in Brazil, Anisembiidae is represented by 13 species belonging to six genera (see details in Catalog).

Diagnosis

10T with completely separate hemitergites, 10Lp1 and 10Rp1 usually with discoidal form ending with a spine. H globose, Hp elongate, ending with a complex apical margin, in some cases ending in a spine-shaped lobe, in other cases ending truncated or in two small lobes; Rpp totally fused to Hp and almost inconspicuous.

Composition and distribution

According to Szumik (1996), Szumik et al. (2008), and the last cladistical analysis of the Order (Szumik et al. 2019), the genera Pelorembia, Dactylocerca, Schizembia, and Cryptembia were previously treated as probable junior synonym of Chelicerca and here these synonymies are confirmed (see below for relationships). Thus, the genus Chelicerca contains 76 species distributed from the southern United States to Argentina (Szumik 1998b, 2001; Ross 2003). In Brazil six species described by Ross (2003) occur and one new species described below. Four of the species described by Ross (2003) were originally described in Cryptembia, here designated a new junior synonym of Chelicerca.

Herein we only list the seven species of Chelicerca present in Brazil: Chelicerca achilata sp. nov., see below; Chelicerca amazonica (Ross, 2003) comb. nov.; Chelicerca manauara (Ross, 2003) comb. nov.; Chelicerca paraense (Ross, 2003) comb. nov.; Chelicerca rioensis Ross, 2003; Chelicerca rondonia (Ross, 2003); Chelicerca rossi nom. nov. because Chelicerca rondonia Ross, 2003 is a junior primary homonym of Cryptembia rondonia Ross, 2003 and is transferred to Chelicerca (see Catalog). New locality records for C. manaurara are added for two states of Brazil (see Catalog).

Distribution

America.

Relationships

Chelicerca appeared as a paraphyletic group in all the phylogenetic analyses performed for the Order Embioptera (Szumik 1996; Szumik et al. 2008, 2019; Miller et al. 2012). Pelorembia and Dactylocerca appeared included in the Chelicerca clade and therefore were proposed as junior synonyms of Chelicerca by Szumik (1996). Subsequently, and by including new taxa and characters, Szumik et al. (2008) found a similar resolution for the three genera plus the inclusion of two other genera, Schizembia and Cryptembia, the five forming a monophyletic group, highly supported by some synapomorphies and almost no homoplasy. In the study of Miller et al. (2012), the three analyzed species of Chelicerca appeared also closely related to Cryptembia and Dactylocerca. As the genera Schizembia and Cryptembia, in addition to Pelorembia and Dactylocerca, appeared as non-monophyletic and their species as members of Chelicerca (Szumik et al. 2019), these four genera are being confirmed and proposed as synonymous juniors of Chelicerca in this work.

Diagnosis

Md acute and small, LC1 symmetrical (processes and setae absent), Hp elongate, Ep narrow (stick-like), wing venation (only veins Rs + Ma and Rs sclerotized and cross veins absent except between R1 and Rs), 10Lp1 and 10Rp1 simple, laminate narrow lobe.

Composition and distribution

Given that Stenembia Ross, 1972 is proposed here as junior synonym of Saussurembia Davis, 1940 (see arguments below under phylogenetic relationships), currently the genus includes seven species: Saussurembia davisi Ross, 1992 from Costa Rica, Saussurembia albicauda Ross, 1992 from Panama, Saussurembia calypso Edgerly et al., 2007 from Trinidad; Saussurembia symmetrica Ross, 1944 from Colombia; Saussurembia perenensis (Ross, 1972) from Peru; Saussurembia exigua (Ross, 1972) from Brazil and the new species described below, also from Brazil.

Distribution

Central and South America.

Relationships

The genus Saussurembia was considered closely related to Stenembia based on the combination of characters discussed and described by Edgerly et al. (2007) for the species Saussurembia calypso which share with Saussurembia the presence of a sclerotized line starting from the inner margin of 10Lp1, the ventrally curved 10Rp1 and the basally broad 10Lp1 with acute apex and, with Stenembia the well-defined Lpp and Rpp, the dorsally curved Lpp and the directed leftward Hp (Edgerly et al. 2007). Saussurembia and Stenembia share many diagnostic characters as Md acute and small, LC1 symmetrical (processes and setae absent), Hp elongate, Ep narrow (stick-like), wing venation (Rs + Ma and Rs are the only veins sclerotized) and the general shape of 10Lp1 and 10Rp1 (with small differences in size and degree of sclerotization) (Edgerly et al. 2007). Thus, one genus is paraphyletic with respect to the other, being Saussurembia the autapomorphic form (Edgerly et al. 2007).

Subsequently, in the phylogenetic analysis of Embioptera (Szumik et al. 2008), the two analyzed species of Saussurembia, S. davisi, and S. calypso, were closely related to two species of Stenembia, S. perenensis, and S. exigua, both genera forming a supported clade. In the last phylogenetic analysis of the Order (Szumik et al. 2019), adding new evidence from legs (ultrastructure of chaetotaxy and the chordotonal organ), the genera continued clustered (Szumik et al. 2019: 9). The only argument used by Ross (1972: 140) when he described Stenembia is that the genus pertains to South America and Saussurembia to Central America. Because the differences between both genera are minimal, we propose Saussurembia Davis as senior synonym of Stenembia Ross.

Family Archembiidae Ross, 2001

The classification proposed by Szumik (2004) elevated Archembiinae Ross to family level with the synonymization and significant delimitation of some genera previously placed as part of the Embiidae by Ross (2001). The cladistic analysis of Szumik (2004) and subsequent phylogenetic analyses of the Order (Szumik et al. 2008, 2019) support Archembiidae as a monophyletic group. The only phylogenetic analysis where Archembiidae appears as non-monophyletic was the study of Miller et al. (2012). Although that work is valid, their analysis shows some inconsistent and unresolved clades, possibly due to the use of a small number of species, to the use of a modified subset of morphological data from the matrix of Szumik et al. (2008), or to a combination of both. They solved the non-monophyly of this group proposing a new classification; delimiting Archembiidae to two genera (Archembia and Calamoclostes) and elevating Scelembiinae to family level and including there the remainder of archembiids. In the last cladistic analysis of the Order (Szumik et al. 2019), with a broader taxon sampling and new included characters, Archembiidae as well as the three subfamilies proposed by Ross (2001) were recovered, corroborating the nomenclatural changes and their monophyly. We propose that Archembiidae includes 21 genera, three fossil genera (from India, Myanmar, and USA) and 18 modern genera (from America and Africa), accounting for a total of 86 species (including the new species described below) (Ross 2001; Szumik 2004; Engel and Grimaldi 2006; Szumik et al. 2008; Engel et al. 2011; Szumik et al. 2019). We also confirm the three subfamilies proposed by Ross (2001) of Archembiinae, Pachylembiinae, and Scelembiinae. Therefore, the genera included in the family Archembiidae Ross are: subfamily Archembiinae (three genera): Archembia Ross, 1971; Calamoclostes Enderlein, 1909; Ecuadembia Szumik, 2004; subfamily Pachylembiinae (four genera): Conicercembia Ross, 1984; Neorhagadochir Ross, 1944 (= Brachypterembia Ross, 1984); Pachylembia Ross, 1984; †Sorellembia Engel & Grimaldi, 2006; subfamily Scelembiinae (14 genera): Ambonembia Ross, 2001 (= Ischnosembia Ross, 2001); Biguembia Szumik, 1997; Chirembia Davis, 1940 (= Navasiella Davis, 1940); Dolonembia Ross, 2001; Embolyntha Davis, 1940 (= Argocercembia Ross, 2001); Gibocercus Szumik, 1997; †Kumarembia Engel & Grimaldi, 2011; †Lithembia Ross, 1984; Litosembia Ross, 2001; Malacosembia Ross, 2001; Ochrembia Ross, 2001; Pararhagadochir Davis, 1940; Rhagadochir Enderlein, 1912 (= Scelembia Ross, 1960); Xiphosembia Ross, 2001.

Here, five new species of Archembiidae from Brazil (one Archembiinae and four Scelembiinae) are described and a complete list of archembiids species and new locality records are added (see Catalog). Thus, in Brazil, the family is represented by 30 species belonging to nine genera.

Subfamily Archembiinae Ross, 2001

Genus Archembia Ross, 1971

Archembia Ross, 1971: 30, type species Archembia lacombea Ross by original designation; Szumik 1996: 51, phylogenetic analysis; Szumik 1997: 141, phylogenetic relationships; Szumik 1998a: 34, new record for the genus in Argentina; Ross 2001: 4, diagnosis and redescription; Szumik 2004: 222, phylogenetic analysis, diagnosis and delimitation of the genus, type species Archembia kotzbaueri (Navas, 1925), senior synonym of A. lacombea; Szumik et al. 2008: 1003, phylogenetic analysis; Szumik 2012: 352, composition; Szumik et al. 2019: 22, tympanal hearing, silk ejectors, leg chaetotaxy, phylogeny.

Diagnosis

Archembia differs from the close related genera Calamoclostes and Ecuadembia by having mandibles with incisive teeth concentrated in the apex, anterior edge of Sm diffuse; apical cerci longer than basal cerci, and medial position of LC1dp (Szumik 2004).

Composition and distribution

According to Szumik (2004) Archembia includes six species, one is known exclusively from Bolivia, Archembia boliviana Ross, 2001 and the other five originally described from Brazil, but recorded in other countries: Archembia kotzbaueri (Navás, 1925), Archembia bahia Ross, 2001, Archembia batesi McLachlan, 1877 also present in Peru, Archembia dilata Ross, 2001 also present in Argentina, and Archembia paranae Ross, 2001, exclusively from Brazil (see Catalog). Here, one new species is described from Brazil. Almost all the species of the genus were described by Ross (1971, 2001), and many of them were not illustrated. In some cases, the criteria used for the creation of a new species were differences on coloration, and a few of these species are now designated junior synonyms (A. peruviana Ross, 2001 and A. lacombea Ross, 1971; see Catalog) or transferred to another genus (Archembia arida Ross, 2001 from Ecuador now Ecuadembia arida (Ross); see Szumik 2004).

Thanks to the observations on Ross’s collection at CAS as well as material deposited at INPA, MZUSP, MCZ, and USNM we have a better understanding of the distribution of this genus, with one species being present in the Amazon basin (A. batesi), four species present in the Atlantic Forest (A. kotzbaueri, A. dilata, A. bahia, A. paranae), and a new species described from the Cerrado and Pantanal ecoregion.

Distribution

South America.

Relationships

Several cladistic analyses suggest that Archembia is a well-supported genus (Szumik 2004; Szumik et al. 2008, 2019). Archembia is one of the basal genera of Archembiidae. The genera Ecuadembia and Calamoclostes are the sister group of Archembia they share the type B vein origin, a large anal area, the straight 10Lp1 with a spatulate apex and the Ep fused to the 10Rp1 (Szumik 2004; Szumik et al. 2019); the three genera conform the subfamily Archembiinae.

Argocercembia Ross, 2001: 63, type species Argocercembia guyana Ross; Szumik 2004: 226, junior synonym of Embolyntha Davis.

Diagnosis

Embolyntha can be distinguished from other Archembiidae by Sm with anterior margin membranous, 10Lp1 simple and starting at inner caudal angle of 10L, 10Lp1 leaf-like with many longitudinal carinae (Szumik 2004).

Composition and distribution

Embolyntha has two species (Szumik 2004): Embolyntha brasiliensis (Gray, 1832) from Brazil (without any specific location) and Embolyntha guyana (Ross, 2001) from Guyana and Brazil (see Catalog for details). In addition, one new species from Brazil is described below.

Distribution

South America.

Relationships

Argocercembia was synonymized with Embolyntha by Szumik (2004) because of the minimal differences between them. Both taxa appeared grouped together by sharing 10Lp1 shape, a small medial bladder in males, and LC1dp in a medial position, both forming a well-supported group. In the higher classification of the Order (Szumik et al. 2008: 927), the genus remains monophyletic and as sister group of the monotypic genus Ochrembia. Finally, these groups remain supported in a more recent study (Szumik et al. 2019: 9) where new evidence from ultrastructure traits on leg chaetotaxy as well as the chordotonal organ were included.

Genus Pararhagadochir Davis, 1940

Pararhagadochir Davis, 1940a: 181, type species Embia trinitatis de Saussure by original designation; Davis 1942: 114, diagnosis; Ross 1944: 420, review; Szumik 1996: 50–51, phylogeny; Szumik 1997: 140, 141, phylogeny, relationship with other Neotropical genera; Ross 2001: 26, genera key, 43, review, diagnosis; Szumik 2004: 225, phylogeny, 230, diagnosis, composition and distribution; Szumik et al. 2008: 1003, phylogeny; Miller 2009: 11, catalog; Szumik et al. 2017: 339, as outgroup of Gibocercus Szumik and Biguembia Szumik phylogenetic analysis; Szumik et al. 2019: 9, chordotonal organ, phylogenetic analysis; Salvatierra 2020: 387, species key.

Diagnosis

Pararhagadochir can be distinguished from other Archembiidae by having the anterior margin of Sm strongly concave, 10Lp1 apically forked with the internal tip (hook) and the external tip (flat lobe) separated, with both tips always shorter than the width of 10L. It can be differentiated by the presence of a sclerotized node between 10L and the base of LC1 and 10Rp2 with more than one longitudinal laminate keel (Szumik 2004).

Composition and distribution

The genus is known from Colombia to Argentina and includes 16 species (Szumik 2004): Pararhagadochir trinitatis (de Saussure, 1896) from Trinidad and Venezuela, P. surinamensis (Ross, 1944) from Surinam, P. balteata Ross, 1972, P. bicingillata (Enderlein, 1909), P. castaneus Salvatierra, 2020, P. christae Ross, 1972, P. minuta Ross, 2001, P. noronhensis Costa-Pinto et al., 2021 from Brazil (see Catalog), P. flavicollis (Enderlein, 1909), P. tenuis (Enderlein, 1909) from Bolivia; P. confusa Ross, 1944, P. schadei Ross, 1944, from Paraguay and Argentina; P. birabeni (Navas, 1918), P. pallida Ross, 2001, P. trachelia (Navas, 1915) from Argentina and P. picchua Ross, 2001 from Peru. Recently, P. confusa was also found in Brazil (Teixeira et al. 2018a). In addition, three new species from Brazil are described below and new locality records for the species P. balteata, P. bicingillata, P. christae, and P. confusa are added; the number of species of Pararhagadochir present in Brazil increases to ten.

Distribution

South America.

Relationships

Pararhagadochir is clearly a monophyletic genus (Szumik et al. 2008, 2019), supported by several synapomorphies (detailed in the diagnosis of the genus). The sister group is a genus from East Africa, Chirembia.

Family Clothodidae Enderlein, 1909

Clothodidae is considered the most primitive family of the Order as a result of the simplicity of its morphological characters (Davis 1939a; Ross 1970, 1987; Szumik 1996). This family contains three fossil genera from Myanmar, Atmetoclothoda Engel & Huang, 2016 (see Engel et al. 2016); Gnethoda Cui & Engel, 2020 and Henoclothoda Cui & Engel, 2020 (see Cui et al. 2020), and five extant genera that have a mostly South American distribution with only one species from Panamá; they comprise a monophyletic group usually separated from the remaining embiids, and includes the following genera: Antipaluria Enderlein, 1912; Chromatoclothoda Ross, 1987; Clothoda Enderlein, 1909; Cryptoclothoda Ross, 1987; and Nonaia Engel, 2020 (see Cui et al. 2020).

Here, one new species is described for the family Clothodidae and new locality records are added. In Brazil, the family is represented by five species belonging to three genera (see Catalog).

Genus Chromatoclothoda Ross, 1987

Chromatoclothoda Ross, 1987: 26, type species Chromatoclothoda elegantula Ross by original designation; Szumik et al. 2008: 997, cladogram; Miller 2009: 12, catalog; Szumik et al. 2019: 9, tympanal hearing, silk ejectors, leg chaetotaxy, phylogeny.

Diagnosis

Chromatoclothoda can be distinguished from the other three genera of Clothodidae by having the male left paraproct well developed as a plate (Fig. 47), instead having both paraprocts (left and right) subequal (e.g., Ross 1987: fig. 4).

Composition and distribution

Chromatoclothoda is a South American genus which contains five species exclusively distributed at the Amazon basin (including the new species described below): one Peruvian species, Chromatoclothoda aurata Ross, 1987; C. albicauda Ross, 1987 from Colombia and Ecuador; C. neblina Szumik, 2001 from Venezuela and two Brazilian species, C. elegantula Ross, 1987 and the new species. For C. elegantula new records are added (see Catalog). The Peruvian species, C. nana Ross, 1987 and C. nigricauda Ross, 1987, were recently transferred to the genus Nonaia (Cui et al. 2020).

Distribution

South America.

Relationships

Chromatoclothoda resulted monophyletic in two phylogenetic analyses of the Order (Szumik et al. 2008, 2019); the species of Chromatoclothoda share the following synapomorphies, all of which are male conditions: Md with one molar tooth; ecdysial suture inconspicuous; medial bladder size less than 40% of the width of the basitarsus; anterolateral face of hind basitarsus with one or two rows of setae; auditory organ of fore femur curved, as a slender band, elongated along the femoral axis. Chromatoclothoda and Clothoda are sister groups (Szumik et al. 2008, 2019) and are supported by sharing some “absences”, for example, the 10Lp1 is not developed and the 10Rp1 is almost inconspicuous.

Etymology

This species is dedicated to Langa, a childhood friend of Lucia and Victoria (Claudia’s daughters).

Family Teratembiidae Krauss, 1911

Teratembiidae family is composed of five genera and considered a monophyletic group and sister group to Oligotomidae family (Ross 1952; Szumik 1996; Szumik et al. 2008; Miller et al. 2012; Szumik et al. 2019). Includes the genera Diradius Freiderichs, 1934; Oligembia Davis, 1939; Teratembia Krauss, 1911 from the American continent, Paroligembia Ross, 1952 from Africa, and Dachtylembia Poolprasert, 2014 from Thailand. In Brazil, the family is represented by seven species belonging to three genera: Diradius pusillus Friederich, 1934; D. plaumanni (Ross, 1944); D. unicolor (Ross, 1944) comb. nov.; O. bicolor Ross, 1944; O. versicolor Ross, 1972; Teratembia producta Ross, 1944, and a new record reported here, T. bancksi Davis, 1939. New locality records are added as well as a complete list of the species known for Brazil (see Catalog).

Catalog of Embioptera present in Brazil

The list of species occurring in Brazil (not including introduced species like Oligotoma saundersii Westewood; for details see Poolprasert 2012) is presented, with new combinations, new species, and new records are in bold.
