Revision of the Afrotropical genus Fainia Zumpt, 1958, with notes on the morphology of Rhiniidae subfamilies (Diptera, Oestroidea)

The taxonomy and diversity of Zumpt, 1958, an exclusive Afrotropical genus, had not been reviewed recently. The genus included six nominal species, but the status of several of them was debated. Identification of most species depends on characters of the male terminalia; females are poorly known and, in several cases, are not adequately diagnosed. We conducted a taxonomic revision of the genus and generated identification tools. Based on the study of type material and specimens available in entomological collections in Africa and Europe, we recognise here three of the six species as valid ( (Macquart, 1846), (Bezzi, 1908) and Zumpt, 1973). We also provide an identification key to both sexes, redescriptions of the species, updated distribution records and high resolution photographs of males' and females' habitus and male terminalia. The description of Lehrer, 2007a is an invalid nomenclatural act in terms of ICZN Article 13.1.1. Based on examinations of their holotypes, Lehrer, 2008 is proposed as a junior synonym of ; Lehrer, 2007b is proposed as a junior synonym of ; and Lehrer, 2007b is moved from the genus to the genus Robineau-Desvoidy, as (Lehrer, 2007b) . We propose two apomorphies that support the status of the subfamily Rhiniinae.
