Pirunipygus paradoxus Roewer, 1936: 341, fig. 4 (♂); Kury 2003: 106; (male holotype, Peru, Junin, Tarma, SMF 6180/85, examined).

Description.

Penis (Fig. 5 B–C; holotype): ventral plate sub hexagonal, deep U-cleft on distal margin, 3-4 distal pairs of setae (2-3 distalmost curved), 2 pairs of dorsal median setae of moderate size, 2 pairs of ventral median small setae. Stylus wide on basal ¾, apex twisted, with a patch of ventral subapical trichomes and some scattered apically. Glans without dorsal and ventral processes.

Taxonomical note.

Both Neopachyloides peruvianus and Pirunipygus paradoxus were formerly placed in Gonyleptidae , Pachylinae . These two species show the following diagnostic characteristics of Ampycinae ( Kury 2003), viz., body coloration black, integument with huge rounded tubercles, stout apophysis on free tergite III, ventral plate of penis with deep U-shape cleft on distal margin, absence of dorsal and ventral processes of glans.
