Psorophora (Grabhamia) varinervis (Diptera: Culicidae) Morphological Description Including Pupa and Fourth-Stage Larva Previously Unknown

Abstract

Psorophora (Grabhamia) varinervis Edwards (Diptera: Culicidae) is redescribed in the adult stage. Pupa and fourth-stage larva are described and illustrated for the first time. Information about distribution, bionomics, and taxonomy also is included. Adults of Ps. varinervis can be separated from the closely related species Ps. (Gra.) discolor (Coquillett) on the basis of the wing characters, and the larva by the siphon and antenna characters.
