Resumo

Two new species of Heteropachylinae Kury, 1994, are described: Magnispina robusta sp. nov. and Magnispina bahiana sp. nov., both from Serra Bonita Natural Reserve, Camacan, Bahia, Brazil. Magnispina robusta sp. nov. is diagnosed by: free tergites II-III with tubercles on their lateral margins, free tergite III without median armature, dorsal anal operculum with a robust bifurcate median apophysis, femur IV slightly curved (convex side outwards) in dorsal view and straight in lateral view, with a basal, a robust median and a subapical apophyses on dorsal face. Magnispina bahiana sp. nov. is diagnosed by: medium size of the median apophysis on free tergite II, free tergite II with bifurcate tubercles on its lateral margins, femur IV with a robust dorsomedian apophysis and prolateral row of tubercles increasing in size apically. We performed a cladistic analysis based on a modified version of the character matrix of the previous revision of the subfamily. We retrieved a single most parsimonious tree (308 steps, CI = 0.43 and RI = 0.61), which corroborates the monophyly of Heteropachylinae, Magnispina Mendes, 2011, Pseudopucrolia, Roewer, 1912 and Heteropachylus Roewer, 1913. The two latter genera comprise a clade that is sister-group to Magnispina. (AU)
