TABLE 2. Comparative account of diagnostic features of the two members of the crassus -species-group, Pachylus crassus (Roewer, 1943) and Pachylus quinamavidensis Muñoz [-Cuevas], 1969.
Pachylus crassusPachylus quinamavidensisArea V of DS: pair of paramedian tuberclesrounded, similar in size to others in same row (Fig. 1A)conical, larger than others in same row (Muñoz 1969: figs 1–2)Stigmatic segment: concavity of posterior marginnarrow, trapezoid-shaped, extending between stigmata (Fig. 4A)curved, situated behind stigmata (Fig. 4B)Stigmatic segment: armatureunarmed, no apophyses on posterolateral corners (Fig. 4A)each posterolateral corner bearing a short blunt apophysis (Fig. 4B)Coxa IV: prolateral apophysiswith simple tip, directed backwards (Fig. 4C); with a slight retroventral tuberosity (Fig. 1A)truncate, tip bilobate and curved, oriented diagonal to axis of body (Fig. 4D); no ventral tuberosityTrochanter IV: prolateral apophysislarge, ear-like, set back to distal end (Fig. 4C)medium-sized, truncate, in middle of article (Fig. 4D)Trochanter IV: retrolateral and retroapical apophysesretrolateral one large, blunt; retroapical one large (Fig. 4C)retrolateral one absent or rudimentary; retroapical one small (Fig. 4D)Femur IV: size and curvature in lateral viewslender, rather long (77–92% of DS length); angle ~150°thick, rather short (67–73% of DS length); angle ~120°Femur IV: dorsal apophysisabsentvery small or reduced to a granulous bulgePatella IV: armaturecompletely unarmed (Fig. 4E)with 1–2 retroventral apophyses (Fig. 4E)
