A new species Dioxys From Southern Spain, with Notes on the Classification of Dioxyini (Hymenoptera: Megachilidae)

Abstract

A new Palearctic species of the cleptoparasitic bee genus Dioxys Lepeletier & Audinet-Serville (Megachilinae: Dioxyini) is described and figured from southern Spain. Dioxys falsificus sp. n. is most similar to D.pumilus Gerstäcker, a species that occupies areas more easterly around the Mediterranean (at least from Sardinia eastward and potentially in eastern Morocco eastward). It is possible that historical records of D. pumilus from southern Spain apply to D. falsificus. A revised key is provided to the genera of Dioxyini, and the South African Dioxoides alata Michener is transferred to Notodioxytes gen.n.
