ABSTRACT
The taxonomic comprehension of Brazilian entomobryids had several contributions during the last decade, but the absence of detailed chaetotaxic schemes to most of endemic species difficult identifications and probably hides undescribed species in surveys across the country. Herein we describe two new species of the family and provide detailed dorsal chaetotaxy of them, in hope to guide future identifications and descriptions within the genera in Brazil and Neotropical Region. Lepidocyrtus sotoi sp. nov. is possibly more related to L. biphasis due to the lack of antennal and leg scales, but presents a unique dorsal head chaetotaxy among the Neotropical species of the genus. Entomobrya bahiana sp. nov. presents an uncommon color pattern and dorsal chaetotaxy in Th. II-III, Abd. II and IV when compared to other Entomobrya spp. from Neotropical Region.

Two new species, Seira coroatensis sp. nov. and Seira diamantinae sp. nov., from different areas of Caatinga Biome, Northeastern Brazil, are described and illustrated in this paper. Seira coroatensis sp. nov. share some similarities with Seira mendoncae Bellini & Zeppelini and Seira ritae Bellini & Zeppelini, but presents a very distinct pattern of setae on dorsal head and mesothorax. In the other hand, Seira diamantinae sp. nov. is the fifth neotropical species described bearing modified blunt macrosetae on distal manubrium and proximal dens. The detailed dorsal chaetotaxy of S. paraibensis Bellini & Zeppelini and S. glabra Godeiro & Bellini are presented with some notes regarding the original descriptions of the species.

Three new species of Seira Lubbock, Seira jiboiensis sp.nov., Seira primaria sp. nov. and Seira harena sp.nov. from Neotropical Region are described and illustrated. All species were collected from humid areas of Caatinga Biogeographic Domain, northeastern Brazil. Seira jiboiensis sp.nov. shows some similarities with S. mendoncea Bellini & Zeppelini and S. ritae Bellini & Zeppelini, while S. primaria sp.nov. resembles S. pseudoannulata Bellini & Zeppelini and S. paraibensis Bellini & Zeppelini in dorsal chaetotaxy in some aspects. Seira harena sp.nov. belongs to a subgroup of Seira originally described in the subgenus Lepidocyrtinus Börner, which has modified macrochaetae on distal manubrium and proximal dens, like S. prodiga (Arlé), S. xinguensis (Arlé) and S. nigrans (Arlé).
