Deltaspidium Roewer, 1927 is a genus of Progonyleptoidellinae Gonyleptidae. It has 3 species from SE Brazil[1].
Distribution[1][]
Deltapisdium spp. were recorded in Serra dos Órgãos mountain range, and Tijuca, both in central Rio de Janeiro State, Brazil. The type-species of the genus has no Brazilian locality explicitly assigned. However, the collectors of the type material, J.B. Spix and C.F von Martius collected in Rio de Janeiro State.
Diagnosis[1][]
Deltaspidium can be distinguished from the other genera of Progonyleptoidellinae by the following combination of characters: dorsal scutum outline (Fig. 8) gamma triangular (γT); mesotergum divided into three scutal areas; posterior margin of DS convex or sub straight; scutal areas I–II unarmed; area III armed with two paramedian spines directed posteriorly (greater and closer to each other in some females); coxa IV with large proapical apophysis with curved apex in males, reduced and straight females; femur IV without DBA, similar in both sexes; tarsus IV with more than 16 tarsomeres; penis with deep cleft on VP, lateral lobes placed sub basally; VP trapezoid, without globous base in lateral view; MS A + B placed in line; MS B smaller than MS A; MS C straight; flabellum with one apical long projection; stylus sub sigmoid, parallel to ventral process shaft.
