Diagnosis.

Paridris pantex may be distinguished from all known species in this genus by the dense tufts of setae on anteromedial S2.

Etymology.

The epithet “pantex”, meaning “paunch” is given to this species for the dense tufts of setae on anteromedial S2. The name is treated as a noun in apposition.
