Scaponopselaphus diaspartos |
The genus is rather easy to tell apart from other Xanthopygina rove beetles thanks to a unique morphological feature: the first tarsomere of the mesotarsus in males has spatulate setae. This is unheard of in other genera of Xanthopygines and that makes it a nice and easy diagnostic feature.

Spatulate setae are very common on the protarsi of rove beetles, but not so much on meso- or metatarsi.
The epithet of the new species (diaspartos) means "scattered" and refers to the distribution of the peg setae on the ventral side of the paramere.
