A new subgenus in Wyeomyia (Diptera: Culicidae), with the reclassification and redescription of the type species, Sabethes fernandezyepezi.

Sabethes femandezyepezi is transferred to the genus Wyeomyia and designated as the type species of a new subgenus named Caenomyiella. The subgenus and species are described and contrasted with certain other nominal taxa in Wyeomyia. The larval and pupal exuviae of an undescribed species from Colombia contributed to the concept of the subgenus.
