Coetzeemyia, a new subgenus of Aedes, and a redescription of the holotype female of Aedes (Coetzeemyia) fryeri (Theobald) (Diptera: Culicidae)

摘要

Coetzeemyia, a new subgenus of Aedes Meigen (in the broad traditional sense, pre-Reinert 2000), is characterized and diagnosed. Aedes fryeri (Theobald) is removed from the subgenus Levua Stone and Bohart (genus Levua of Reinert et al. 2004) and placed in the new monotypic subgenus Coetzeemyia as its type species by present designation. Recognition of Coetzeemyia is based in part on a cladistic analysis of 16 species: seven outgroup species (four non-Aedini species and 3 aedine species) and nine within group species, including the three species that had been included in Levua and six other species belonging to three related subgenera in Aedes (Geoskusea Edwards, Rhinoskusea Edwards, and Ochlerotatus-Lynch Arribalzaga). The type female and the male genitalia of Ae. fryeri are redescribed and illustrated. Its affinity to other subgenera of the genus Aedes is discussed. Information on the type data, distribution, bionomics, medical importance, and taxonomy of this species are presented. Some morphological characteristics of adults of the subgenera Ochlerotatus and Levua of Aedes are tabulated. Based on this cladistic analysis, it is evident that Levua is a monotypic lineage represented by a single known species, Ae. geoskusea. Aedes dufouri is transferred back to the subgenus Ochlerotatus and is distinguished from other congeners of this subgenus.
