Labiobaetis vinosus

= L. tenuicrinitus , syn. n.

The Afrotropical species under the name Pseudocloeon vinosum Barnard 1932 was originally described as male and female imagines and larvae from South Africa and then moved in the genus Labiobaetis by Lugo-Ortiz and McCafferty (1997b). The species under the name Pseudocloeon tenuicrinitum Kopelke 1980 was originally described as male and female imagines ( Kopelke 1980a) and eggs ( Kopelke 1980b) from Zaire (recently DR Congo); nobody compared P. tenuicrinitum with P. vinosum . Based on imagines reared from larvae in Uganda, Kluge and Novikova (2016) moved P. tenuicrinitum in the genus Labiobaetis , redescribed its larvae, subimagines, imagines and eggs and established its synonymy with the species originally described from Tanzania as Baetis spatulatus Gillies 1994 . At present, examination of larvae, reared imagines and eggs from Tanzania and South Africa allows to conclude that the names vinosum [ Pseudocloeon ], tenuicrinitum [ Pseudocloeon ] and spatulatus [ Baetis ] belong to one and the same species.
