Abstract
Dichelacera (Dichelacera) walteri Guimarães, Gorayeb & Rodrigues-Guimarães n. sp. is described from female specimens collected in Marambaia Island, located in Mangaratiba County, state of Rio de Janeiro, Brazil. The characterization of the species was based in the following characters: a medium-sized species, more sclerotized than others in the subgenus Dichelacera Macquart, the second segment of palp with dark setae and longer than the third antennal segment, a brown scutum with pruinescence on the anterior half and posterior edges with white tonality, yellow dorsum of abdomen with the last three segments brown, white-yellowish venter with yellow setae, narrow frons with dark brown callus, extending just beyond a ridge in the middle of the frons, vertex with ocelli, hyaline wings with three large black bands, and tricolored legs.
