Paridris skolops is unique among the Paridris species in Fiji because the female has a carina along the posterior margin of the antecostal sulcus on T2. Males and females have a setose metasomal depression and dense fine setae along the postgena which serve to separate them from the other species treated in this revision.
The Greek epithet “skolops” meaning "anything pointed" refers to the posteriorly directed spine on the horn of T1 in females of this species. The name is treated as a noun in apposition.
