Aristobatina Verbeke is redefined and reviewed, and four new species, namely A. melasma, A. metamelasma, A. morogoro and A. udzungwa from the Eastern Arc Mountains of Tanzania are described. The diagnosis of Aristobatina is expanded to include species with outer vertical setae. Aristobatina is compared to Tanypomyia Verbeke and the latter genus is removed from synonymy with Mimegralla Rondani.
