Recognition of mosquito subspecies: the case for Aedes aegypti (Diptera: Culicidae).

We address the recent proposal by Harbach and Wilkerson to eliminate all Culicidae (mosquito) subspecies names. We defend and promote the use of subspecies for the important vector Aedes aegypti (L.): Aedes aegypti aegypti and Ades aegypti formosus. Harbach and Wilkerson would raise the latter to Aedes formosus. We briefly review evidence on this group with relation to various species concepts and find little or no support for this species designation. The 2 forms fit most concepts of subspecies and we advocate continued use of subspecies. Workers on other culicid groups may wish to retain subspecies when accurate, useful, and stable (historical continuity).
