2(1). Mandibular plates longer than clypeus not contiguous ( Fig. 2 ); antennal segment I barely reaches apex of mandibular plates; superior process of dorsal rim of pygophore oblique at dorsal rim, projecting towards base of parameres for 1/3 of the distance from dorsal rim to base of parameres; ventral rim of pygophore indented medially, margin of indention parallel............................................................................

3’. Head wider than longer; apex of labium at most reaching abdominal segment III; mandibular plates longer than clypeus, convergent and juxtaposed apically.......................................................................... 5

4(3) Body with dark-brown, longitudinal spots on pronotum and scutellum; humeral angles projected postero-laterad ( Fig. 4 ); posterolateral angles of pygophore with a small spine-like tubercle laterally; superior process of dorsal rim of pygophore quadrangular apically, projecting towards base of paramere; posterior margin of gonocoxites 9 bilobed........................................................................................... P. vittatus Grazia, Becker & Thomas, 1994

4’. Body with dark-brown spots irregularly distributed on pronotum and scutellum; humeral angles projected laterad ( Fig. 1 ); posterolateral angles of pygophore lacking a small spine-like tubercle; superior process of dorsal rim of pygophore spatulate apically, not projecting towards base of paramere; posterior margin of gonocoxites 9 concave.......

P. angelomachadoi Grazia & Bolze sp. nov.

6(5) Processes of abdominal segment X well-developed, projected posteriorly and well surpassing the posterolateral angles of the pygophore; superior processes of dorsal rim of pygophore spatulate dorsally; sutural and posterior margins of gonocoxites 8 reflexed ( Fig. 6 ).......................................................... P. roraimensis Grazia & Greve, 2002
