Three new species of Seira Lubbock (Collembola, Entomobryidae) from Caatinga Domain, northeastern Brazil.

ABSTRACT

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).
