Diagnosis

The male of this species can be easily separated from congeners by the shape of the palpal tibial apophysis which is straight with a blunt tip, while curved and pointed in other species.

Etymology

The specific name is Latin, meaning ‘straight’, and refers to the shape of the tibial apophysis of the palp.
