Redescription and placement of Wyeomyia rorotai Senevet, Chabelard Abonnenc (Diptera: Culicidae) in the subgenus Decamyia based on morphological and molecular analyses

摘要

Decamyia Dyar is a subgenus of Wyeomyia Theobald with three valid species. Wye ontyia rorotai Senevet, Chabelard & Abonnenc, a species originally described rather briefly in the subgenus Dendromyia, is without subgeneric position in the genus. In the present work, we redescribe Wy rorotai in all life stages and formally define its taxonomic placement in the subgenus Decamyia by combining morphological and molecular analyses based on the mitochondrial cytochrome c oxidase subunit I gene. We also show that Decamyia is a rather homogeneous group of four species, i.e. Wy. ulocoma (Theobald), Wy. pseudopecten Dyar & Knab, Wy felicia Dyar & Nunez Tovar and Wy. rorotai, the inunature stages of which almost exclusively inhabit the flower bracts of Heliconiaceae.
