Abstract:
Three new species of the Neotropical genus Tacora MELICHAR, 1926 are described and illustrated: T.
henriquesi sp.n. (Brazil: Acre State; Peru: Madre de Dios Departrnent), T. cavichiolii sp.n. (Brazil: Mato
Grosso State), and T. karipuna sp.n. (Brazil: Rondônia State). A taxonomic key to males of the five known
species is also provided, including the type-species T. dilecta (WALKER, 1851) and T. saturata YOUNG,
1977. Notes on the phylogenetic position of the genus Tacora are given, and its possible sister group
relationship with Dasmeusa MELICHAR, 1926 is discussed. lt is suggested that the common ancestor of
Tacora and Dasmeusa species were distributed throughout the Amazon basin, and was segregated by a
vicariant event that isolated the Tacora ancestor in Western Amazonia (Napo and lnambari and possibly
Imerí areas of endemism).
