Taxonomic Study of Species Formerly Identified asAnopheles mediopunctatusand Resurrection ofAn. costai(Diptera: Culicidae)

Anopheles (Anopheles) mediopunctatus (Lutz) and Anopheles (Anopheles) costai Fonseca & Ramos are redescribed with illustrations of the male genitalia and larval and pupal stages. The pupa of An. costai has paired lateral projections on the wing case, a feature also known in members of the Umbrosus Group from Southeast Asia. An. costai is resurrected from the synonymy of An. mediopunctatus based on features of the male genitalia, larva, and pupa, and An. bonneorum Fonseca & Ramos (emended from bonnei) is considered to be a new synonym of An. costai. It is noted that the author of An. mediopunctatus is Lutz, not Theobald, as cited in most literature references.
