Intraespecific variation on the aedeagus of Anopheles oswaldoi (Peryassú) (Diptera: Culicidae).

Anopheles (Nyssorhynchus) oswaldoi (Peryassú) comprises a species complex in South America. Specimens from two localities in east Mata Atlântica were characterized both at the morphological and molecular level as An. oswaldoi s.s. Intraspecific variation of the shape of the apex of the aedeagus of the male genitalia of specimens of Anopheles (Nyssorhynchus) oswaldoi s.s. from Vale do Ribeira, Mata Atlântica, São Paulo State, Brazil, was observed. Distinctive aedeagus of the specimens from Vale do Ribeira, Mata Atlântica, were evaluated, illustrated and compared to that of An. oswaldoi s.s.
