Revision of Wyeomyia (Hystatomyia) Dyar & Knab (Diptera: Culicidae: Sabethini

Creator:: Adkins, Jessica Y.
Abstract:: Members of the tribe Sabethini (Diptera: Culicidae) oviposit and develop in phytotelmata (plant-held waters) and are primarily distributed in a pantropical pattern. Recent cladistic studies have demonstrated that while the tribe is monophyletic, three of its 13 genera are not. The genus Wyeomyia is particularly problematic and debate among culicidologists...
