Type species: Pilia saltabunda Simon, 1902 (by original designation).
Diagnosis. Pilia is most similar to Bristowia Reimoser, 1934 in having long and robust first pair of legs, tibia I with dense fringe of long, thick hairs ventrally. But it differs from Bristowia by: Carapace with a bunch of thick hairs just inward of each PLE (absent in Bristowia) (Simon 1903; Reimoser 1934; Metzner 2025). Leg I with strongly incrassate femur and tibia (normal but elongated in Bristowia). The male palps have a simple bulb without any projection or bulge (posterior portion of bulb broad and bulged in Bristowia); retrolateral shoulder of tegulum high either above embolic base or slightly lower (significantly lower in Bristowia); distal projection of embolar tegular branch small and insignificant (prominent, projecting beyond retrolateral lobe of tegulum in Bristowia) (see fig. 1a in Deeleman-Reinhold et al. 2024 for terminology); epigyne simple with a pair of circular windows; copulatory duct long with an anterior loop (copulatory ducts bent without any loop in Bristowia); spermathecae elongated, tubular (globular without any other modification in Bristowia) (Szűts 2004; Kanesharatnam & Benjamin 2016).
