Subgenus Wainiella

The subgenus Wainiella Griswold contains 1 Afrotropical species (Michener, 2007; Kuhlmann et al., 2011). According to Griswold and Michener (1998), Wainiella marginally reaches the Palaearctic region in Yemen. Indeed, a Wainiella species was recently found in a sample of bees from Yemen (C. Praz, personal communication). As it is improbable that this species is conspecific with Wainia (Wainiella) sakaniensis from South Africa and DR Congo, the species from Yemen is probably new to science.
