Diagnosis.

Paridris nigriclava  is the only species of Paridris  treated by the present authors in which the frons bears a prominent central keel. Additionally, the punctiform postmarginal vein and convex shape of the metascutellum separate it from the other species of the Seychelles.

Comments.

The species that we here synonymize differ only in color.
