A taxonomic revision of the Neotropical termite genera Labiotermes Holmgren and Paracornitermes Emerson (Isoptera: Termitidae: Nasutitermitinae)

The taxonomy of the South American termite genus Labiotermes Holmgren (sensu novo) is revised, including identification keys to soldiers and workers, and distribution maps for all 10 species. Paracornitermes Emerson is treated as a new synonym of Labiotermes. Two new species are described: L. guasu, from the Amazon rain forest and L. oreadicus, from the Cerrado of central Brazil. Paracornitermes caapora Bandeira & Cancello and P. hirsutus Araujo are placed under the synonymy of L. orthocephalus. The imagos of L. emersoni and L. orthocephalus are described for the first time. The workers of all species are described and illustrated, including the enteric valve armature and the mixed segment. The soldiers of the species previously included in Paracornitermes are redescribed.

Respective Species

The South American genus Panca Evans, 1955 and its respective species are revised. Previous to this study, the genus included solely its type species, Lerodea subpunctuli Hayward, 1934, until Panca moseri Dolibaina, Carneiro & O. Mielke, 2017 was described recently. However, as a result of a broader morphological study including closely related genera, we here propose that Panca assembles 12 species, most of which inhabit open environments such as the Cerrado biome and the natural grasslands of the Atlantic Forest biome. Eight species formerly included among other genera of Moncina are here combined with Panca: Panca satyr (Evans, 1955) comb. nov., Panca tobiasi (Mielke, 1992) comb. nov., Panca trogon (Evans, 1955) comb. nov., Panca steinhauseri (Dolibaina & A. Warren, 2015) comb. nov., Panca acroleuca (Plötz, 1884) comb. nov., and Panca mirnae (O. Mielke, Dolibaina, Carneiro & A. Warren, 2015) comb. nov. (all formerly in Artines Godman, 1901), Panca paulo (Bell, 1932) comb. nov. (formerly in Eutocus Godman, 1901), and Panca mictra (Evans, 1955) comb. nov. (formerly in Vidius Evans, 1955). Additionally, two new species are described from Brazil: Panca puri Medeiros, O. Mielke & Casagrande sp. nov. (from Pará, Pernambuco, Minas Gerais, Rio de Janeiro and Paraná) and Panca xavante Medeiros, O. Mielke & Dolibaina sp. nov. (from Mato Grosso, Goiás, Distrito Federal and Minas Gerais). A neotype for Apaustus acroleuca Plötz, 1884 is designated. Illustrations of the male and female genitalia and distribution maps are presented for all the species of Panca and an identification key is provided for both sexes.

In this paper, M. yanomami n. sp., from Brazilian Amazonia, Chaetacis bandeirante n. sp., from Central Brazil, and the males of M. gaujoni Simon, 1897 and M. ruschii (Mello-Leitão, 1945) n. comb. , respectively from Ecuador and Brazil, are described and illustrated for the first time. An ontogenetic series of the last development stages of both sexes of Micrathena excavata (C. L. Koch, 1836) is illustrated and briefly described. Adult females are larger and have longer legs and larger abdomens than adult males. Probably females undergo at least one additional moult before adulthood, compared to males. Micrathena ornata Mello-Leitão, 1932 is considered a junior synonym of M. plana (C. L. Koch, 1836), and M. mastonota Mello-Leitão 1940 is synonymized with M. horrida (Taczanowski, 1873). Acrosoma ruschii Mello-Leitão, 1945 is revalidated, transferred to Micrathena and considered a senior synonym of M. cicuta Gonzaga & Santos, 2004. Chaetacis necopinata (Chickering, 1960) is recorded for Brazil for the first time. Chaetacis incisa (Walckenaer, 1841) is considered a nomen dubium.

Here we present a first contribution to the taxonomic revision of Sisyrinchium (Iridaceae: Iridoideae) for Southern Brazil. Sisyrinchium sect. Cephalanthum is one of the six sections in which the Brazilian species of the genus are classified, and the second largest in number of taxa. This monograph presents the taxonomic treatment of 22 taxa characterized by a unique set of morphological and molecular features, assigned to the section by phylogenetic studies, as well as the unplaced S. elegantulum, which is included here due to morphological similarity. A new status and a new synonym are proposed, and nine lectotypes and one neotype are designated. An identification key is provided, and species are described, accompanied by botanical illustrations, pictures, and distribution maps. In addition, geographical distribution, habitat, phenology, notes, and examined specimens are presented. Species of the section are mainly distributed in the South American biogeographic dominions of Chacoan and Parana.

First Time

Devario comprises 38 potentially valid species in southern Asia. Ten species of Devario have been reported so far from Myanmar, six of which belong in the group of striped devarios, with predominantly horizontal stripes in the colour pattern. Among them, records of D. aequipinnatus most likely represent misidentifications. Remaining species of striped devarios in Myanmar are known only from brief descriptions and are in need of taxonomic revision. Devario yuensis and D. deruptotalea, known previously only from India, are here reported for the first time from Myanmar. Devario fangae, new species, is described on the basis of specimens collected in 1998 from small streams in Putao in the extreme north of Myanmar. These streams drain to the Mali Hka River, a tributary of the Ayeyarwaddy River. Devario fangae shares uniquely with D. browni and D. kakhienensis an anterior expansion in width of the middle dark stripe on the side (P stripe). It differs from D. browni and D. kakhienensis in presence of a broad P stripe, wider than adjacent interstripes, vs. narrow, as wide as or narrower than interstripes. Devario fangae is further similar to other species of Devario characterized by three dark stripes (P, P+1, P-1) along the side, but differs from these in having all three stripes wide and of about equal width vs. P stripe wide and P+1 and P-1 stripes much narrower. The largest specimen of D. fangae is 61.0 mm SL. Females are significantly more deep-bodied than males. A specimen of D. aequipinnatus reported from Putao in 1919 probably represents D. fangae. Devario myitkyinae, new species, is described on the basis of specimens collected in 1997 and 1998 from a stream and lake in the Ayeyarwaddy River drainage near Myitkyina in northern Myanmar. It is similar to D. browni and D. kakhienensis, but different from D. fangae in having horizontal stripes on side equal in width, narrow, irregular, and to some extent curved away from horizontal extension. Devario myitkyinae differs from D. browni, D. kakhienensis, and D. fangae in absence of anterior widening of the P stripe. Devario myitkyinae is similar to other species of Devario characterized by three dark stripes (P, P+1, P-1) along the side, but differs from these in having all three stripes irregular and of equal width vs. stripes regular, P stripe wide and P+1 and P-1 stripes much narrower. The largest wild specimen of D. myitkyinae is 68.7 mm SL. A specimen collected near Myitkyina and reported as D. aequipinnatus in 1929 probably represents D. myitkyinae.

This paper provides a taxonomic revision of the Neotropical ant genus Hylomyrma Forel (1912) (Myrmicinae: Pogonomyrmecini). Morphological traits combined with geographical data and natural history information led to the recognition of 30 species, fourteen of them described here as new: Hylomyrma adelae sp. n., Hylomyrma dandarae sp. n., Hylomyrma jeronimae sp. n., Hylomyrma lispectorae sp. n., Hylomyrma lopesi sp. n., Hylomyrma macielae sp. n., Hylomyrma margaridae sp. n., Hylomyrma mariae sp. n., Hylomyrma marielleae sp. n., Hylomyrma mitiae sp. n., Hylomyrma peetersi sp. n., Hylomyrma primavesi sp. n., Hylomyrma virginiae sp. n. and Hylomyrma wachiperi sp. n. Lectotypes for H. speciosa (junior synonym of H. balzani) and H. reitteri are here designated from syntypes to improve nomenclatural stability. Except for the three species most recently described (H. montana, H. plumosa, and H. villemantae), the external morphology of workers is described or redescribed, as well as for the known males and queens, most described here for the first time. Of the 30 recognized species herein, 11 present intercastes; at least three of them present female specimens with queen-like traits that may be understood as ergatoids. An updated identification key for Hylomyrma workers is provided, as well as high resolution photographs of all known sexes and castes, species distribution maps, and a summary of what is known from the biology of all species.

Biogeographical Province

A taxonomic revision of the Liogenys Guérin-Méneville, 1831 (Coleoptera: Scarabaeidae: Melolonthinae: Diplotaxini) from the Chacoan Biogeographical Province is presented. Liogenys now includes 92 species, including four new species described here: L. neoforcipata Cherman, new species; L. foveata Cherman, new species; L. isotarsis Cherman, new species; and L. truncata Cherman, new species; and the female of L. tarsalis Moser is described for the first time. Six new synonymies are proposed: L. denticulata Moser, 1918 is a new synonym of L. denticeps Blanchard, 1851; L. ophtalmica Frey, 1973 is a new synonym of L. bidenticeps Moser, 1919; L. mendozana incisa Frey, 1969 is a new synonym of L. mendozana Moser, 1918; L. flavicollis Blanchard, 1851 and L. fulvescens Blanchard, 1851 are new synonyms of L. pallens Blanchard, 1851; and L. densicollis Moser, 1921 is a new synonym of L. opacicollis Fairmaire, 1892. Liogenys cribricollis Moser, 1921 species status is revalidated from its synonymy with L. densicollis. A neotype is designated for Liogenys mendozana incisa Frey, 1969, as well as lectotypes for: L. bruchi Moser, 1924; L. cribricollis, L. denticulata, L. denticeps, L. fulvescens, L. latitarsis Moser, 1918; L. mendozana Moser, 1918; L. obscura Blanchard, 1851; L. opacicollis; and L. pallens. Redescriptions and/or diagnoses and updated geographical distributions are provided for 16 species. Six species previously known only from Argentina have their distribution expanded to Bolivia (L. mendozana; L. opacicollis; L. rectangula Frey, 1969), Paraguay (L. nigrofusca Moser, 1918; L. pallens), or to both of these countries (L. latitarsis).
