==Morphology== Pachynomidae range in size from 3.5 to 11 millimetres and often bear a certain resemblance to sickle bugs (Nabidae) from the subfamily Prostemmatinae. The upper surface of their bodies varies from very shiny (genus Pachynomus ) to matte and hairless to heavily hairy. The compound eyes are large, and the head has no constriction behind the compound eyes. Ocelli can be present or absent. The antennae appear to have five segments, with the second segment (pedicellus) divided into two parts. The distal part of the pedicellus usually bears a single trichobothrium. The labium is thick and strongly curved. The thighs (femora ) of the forelegs are greatly enlarged, and the shins (tibiae) of the forelegs bear fossulae spongiosae (specialised hairy structures used for holding on). The eighth abdominal segment of the males is reduced and retracted into the seventh segment. Male genitalia are symmetrical, the pygophore is well developed and apically articulated into the abdomen. The ovipositor of the females is plate-shaped. A spermatheca is missing, but a pseudospermatheca is present.
