Discussion: Ichthyomyini. All named forms suggested as conspecific under trichotis by Hershkovitz (1966 c) but Voss (1988) recognized four species. Formerly included trichotis (Tate, 1932) , a species later designated as the type of Chibchanomys ( Voss, 1988) . Neorheomys , diagnosed as a subgenus ( Goodwin, 1959 a), was placed in full synonymy by Voss (1988). Separation from Ichthyomys questioned by Ellerman (1941) and Hall (1981); relationships, generic stature, and Mesoamerican endemism illuminated by Voss (1988).
