Review of the hydrotaea parva and hydrotaea glabricula groups (Diptera: Muscidae)

Abstract

The fauna of the Hydrotaea parva group and the here proposed Hydrotaea glabricula group is considered. Identification keys for the Eurasian and Afrotropical faunas of the Hydrotaea glabricula group and for the Palaearctic and Eurasian faunas of the Hydrotaea parva group are given. Five new species H. semiflava sp.n. (from Sri Lanka), H. elephans sp.n., H. ozerovi sp.n., H. portschinskyi sp.n. and H. stackelbergi sp.n. (all from Thailand) and one subspecies H. polita kenyana ssp.n. (from Kenya) are described. Two new synonymies are proposed: Hydrotaea atrisquama Ringdahl, 1925 = Hydrotaea multipilosa Shinonaga et Kano, 1983, syn.n. and Hydrotaea parva Meade, 1889 = Hydrotaea exigua Shinonaga et Kano, 1983, syn.n.
