Heteropachylus can be differentiated from Magnispina and Pseudopucrolia by the following combination of characters: Three or four mesotergal areas; mesotergal area III with variable armature. Median armature of free tergite II with length comparable to the length of the tergite. Calcaneus I about half the size of the metatarsus and lighter than the astragalus. Femur IV distinctly curved in dorsal view, with two curvatures (‘S-shaped’) in lateral view; bearing dorsobasal apophysis and row of tubercles on the prolateral margin, rounded at the distal half, larger at the medial portion of the row. Male genitalia. Dorsal digitiform process in glans mostly absent (except in H. crassicalcanei).[1]
