A featherwing beetle without wings: re-discovery and second species of Rioneta (Coleoptera: Ptiliidae) from the Uluguru Mountains, Tanzania
نویسنده
چکیده
The type species of the monotypic beetle genus Rioneta Johnson, 1975, previously known from three specimens, is rediscovered in the Uluguru Mountains, Tanzania. A second sympatric species, R. inexpectata sp.n., is described. The relatively rare event of apparently obligate aptery in Ptiliidae is reported. The genus Rioneta, as well as Leptinla Johnson, 1985, are removed from the non-monophyletic Ptiliini and transferred to the tribe Ptinellini.
