Harpactea hombergi  (DYSDERIDAE)

The family Disderiidae, to which Harpactea hombergi belongs, are "haplogyne" spiders. These are relatively primitive, having only six eyes and simple pedipalps. The epigyne is not easily detected and is not used to determine the females to species level. Rather, the layout and number of spines on femur IV is used instead.
