OCCURRENCE OF MESOPOSTNOTAL SETAE AND SCALES IN THE FAMILY CULICIDAEl

BRUCE A. HARRISON~ AND WILLIAM E. BKKLEY~

ABSTRACT. A surveyof specimensand the literature wasconducted to determine the presence,distribution and possiblephylogenetic significance of mesopostnotalsetae and/or scaleson adultsthroughout the family Culicidae. The distributionin the family is tabulated with detailednotes for the speciesin eachtaxon having the character,and 4 species with the characterare illustrated. The presenceand frequencyof the characterin varioustaxa of the tribes Aedini, Culicini and Sabethini are discussedhighlighting differences in given taxa between the Eastern and Western Hemispheres. Phylogeneticconsiderations regarding the correlation of the character with the /tropics, phytotelmicimmature habitats,and the origin of the current distributionof the characterare discussed.
