Attempting to review the species of sandflies in the series oswaldoi of the subgenus Helcocyrtomyia, we examined 7650 specimens collected in different Brazilian regions during 35 years and deposited in the collection of the Centro de Pesquisas René Rachou, FIOCRUZ, Belo Horizonte, MG. As main results of this study new species of Helcocyrtomyia were described (Lutzomya pusilla and Lutzomya capixaba), in addition to the females of Lutzomyia ferreirana and Lutzomyia peresi; which had been described only by the males. The geographic distribution of the material examined is also presented.

The authors present the list of the species caught in the National Parks of Ubajara and Sete Cidades, in the counties of Ubajara (CE) and Piracuruca (PI), respectively, and described the Lutzomyia (Helcocyrtomyia) samueli (Deane, 1955) female, which up to now had been known by the male.

Os autores descrevem uma nova espécie, Lutzomyia capixaba sp.n., pertencente ao grupo dos flebotomíneos de cinco espinhos do subgênero Helcocyrtomyia Barreto, 1962.

A great number of sandfly specimens belonging to subgenus Helcocyrtomyia Barretto, 1962, deposited in the collection of the Centro de Pesquisas René Rachou was studied. The authors observed the existence of a new species, Lutzomyia capixaba n.sp. whose male is very similar to Lutzomyia oswaldoi (Mangabeira, 1942), but whose female has distinct characteristics from others species of the subgenus.

Os autores redescrevem o macho e descrevem a fêmea de Lutzomyia (Helcocyrtomyia) peresi (Mangabeira, 1942).

The authors redescribe the male and describe the female of Lutzomyia (Helcocyrtomyia) peresi (Mangabeira, 1942).
