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.

First Time

In this contribution we present updates on the taxonomy and morphology of the South American species of Amitermes. Two new species are described: Amitermes bandeirai, sp. n., from Brazil, and Amitermes lilloi, sp. n., from Argentina. Amitermes nordestinus is a junior synonym of Amitermes aporema. The imago of A. aporema is described for the first time. Detailed comparative gut anatomy of the eight species is presented for the first time. The geographic distribution of Amitermes in South America is expanded and the distribution patterns of some species are discussed.

Mexican Species

Two new species of Megarthrus are described from cloud forests of the Mexican state of Veracruz: M. cavianae Rodríguez, Navarrete-Heredia & Arriaga-Varela sp. nov., and Chiapas:  M. chiapas Cuccodoro sp. nov. They differ from the two hitherto known Mexican species M. altivagans Bernhauer, 1929, and M. alatorreorum Rodríguez & Navarrete-Heredia, 2015, both from temperate forests of the Transmexican Volcanic Belt, by having synapomorphic features of the M. inaequalis-supergroup of species. This lineage includes all the Central and South American members of the genus, with the inclusion of these species, the distribution of the group is extend by more than 5 degree of latitude to the North. Within this lineage, the two new species share a very peculiar morphology of the male abdominal sternite VIII found elsewhere in the genus only in M. flavosignatus Bierig, 1940, and M. zunilensis Sharp, 1887, with which they form the M. zunilensis-group of species defined here.

Two New Species

During the analysis of European and American herbaria collections for a taxonomic review of the Brazilian species of Gurania, two new South American species were found.  Gurania jeffreyi occurs in Ecuador and Colombia and Gurania calathina is found only in Colombia. Descriptions and illustrations of the new species are presented with comments on affinities and differences between them and related species.
