Pachygnathus Dugês, 1836
Type species: Pachygnathus villosus Dugês 1836 (=P. ornithorhynchus Grandjean 1937)
Pachygnathus silvaticus de Alzuet & Delgado (selvaticus?)
DIAGNOSIS. Prodorsum with 2 pairs of filiform trichobothria; chelicerae attenuate-edentate,
with swollen bases and nude;
3 pairs of genital papillae in tritonymph and adult. Leg IV not modified for jumping.
