Abstract

Macrosiagon vittata (Erichson), M. mutilata (Gerstaecker) and M. gracilis Manfrini de Brewer are assigned to the new provisional species group vittata on the basis of possessing two protibial apical spurs, a transversely flattened vertex not elevated above the dorsal margin of the eyes and thread-like antennal rami in males. A key to these species is presented and each is redescribed. The following nomenclatural changes are made: M. mutilata (Gerstaecker) (= M. quadrimaculata (Gerstaecker), = M. melanoptera (Chevrolat), = M. vitraci (Fleutiaux and Sallé)) new synonymies, and M. vittata (Erichson) (= M. vittata var. biinterrupta Pic, = M. vittata var. bahiensis Pic, = M. vittata var. latelutea Pic, = M. discicollis (Gerstaecker), = M. brasiliensis Pic, = M. pectoralis Pic) new synonymies. Lectotypes and paralectotypes are designated for the following species: M. mutilata, M. quadrimaculata and M. vittata. A brief discussion of Macrosiagon taxonomy and phylogenetic relationships within the Macrosiagonini is also presented.
