title: Molecular revision of the genus Wallaceina.
abstract: This work is focused on the molecular revision of the genus Wallaceina established in the very twilight of the classical morphotype-based approach to classification of the Trypanosomatidae. The genus was erected due to the presence of a unique variant of endomastigotes. In molecular phylogenetic studies four described species of Wallaceina were shown to be extremely close to each other and to some other undescribed isolates clustered within Leishmaniinae clade, while three recently included species formed a separate clade. Our results of morphological and molecular phylogenetic analyses demonstrated that all Leishmaniinae-bound wallaceinas are just different isolates of the same species that we rename back to Crithidia brevicula Frolov, Malysheva, 1989. To accommodate former Wallaceina spp. phylogenetically distant from the genus Crithidia, we propose a new generic name Wallacemonas Kostygov et Yurchenko, 2014.
