The male of Brumptomyia angelae, sp. nov., a new species of Phlebotominae (Diptera, Psychodidae) of the Atlantic forest of the state of Paraná, Brazil, is described and illustrated. This new taxon is closely related to Brumptomyia ortizi Martins, Silva & Falcão 1971, Brumptomyia nitzulescui (Costa Lima, 1932), and Brumptomyia troglodytes (Lutz, 1922). The male genitalia of these three latter species have also been drawn.

During the entomological surveillance of the Visceral Leishmaniasis Programme in the state of Paraná, Brazil, one male of a new phlebotomine species of Brumptomyia França & Parrot, 1921 was captured. This capture took place in November 2005 in the Ilha Rasa locality, municipality of Adrianópolis, 209 m above sea level, at 24º 39' 06" S and 49º 02' 06" W, in a tunnel, situated in secondary Atlantic forest.

In accordance with the classification of Galati (2003a) the genus Brumptomyia together with Oligodontomyia Galati, 1995 compose the subtribe Brumptomyiina of the Phlebotomini Rondani, 1840 tribe.

Both sexes of Brumptomyiina may be characterized by the more basal position of the external ascoid than the internal one on the 3rd antennomere (AIII); 5th palpomere longer than 3rd, presence of ventro-cervical sensillae, and the setae on the anterior margin of the katerpisternum. Male: gonostyle with five spines, the external ones being implanted in a single tubercle. Female: cibarium presenting the anterior teeth in horizontal position in relation to the lumen; spermathecae segmented with very long individual sperm ducts, four or more times the length of the spermathecae. Brumptomyia presenting ascoids with posterior prolongation and absence of postalar seta; males with a row of stout, straight setae in the apical region of the inner side of the gonocoxite and the female cibaria with horizontal anterior teeth in longitudinal rows and the sclerotized area located posterior to the posterior teeth, all of which distinguish it from Oligodontomyia (Galati 2003b).

The genus Oligodontomyia is composed of three species restricted to the Andean region (Young & Duncan 1994, Leger & Ferte 1996, Le Pont et al. 1997), while Brumptomyia is widespread in the Americas, from Mexico to Argentina (Martins et al. 1978), with 24 species described (Galati 2003a), 14 of them occurring in Brazilian states with Atlantic forest domains (Aguiar & Medeiros 2003, Galati 2003a).



The capture was undertaken with a Falcão trap (Falcão 1981). The specimen was clarified in accordance with the method described by Forattini (1973) and mounted on microscope slides in NC medium (Cerqueira 1943). It was measured with a Zeissâ eye-piece calibrated according to a standard Zeissâ scale and drawn with an Olympusâ clear chamber. All measurements are given in micrometers. The terminology of the characters follows Galati (2003b). The holotype is deposited in the entomological collection of the Faculdade de Saúde Pública of the Universidade de São Paulo (FSP-USP).

The terminalia of the three species considered closest to this new taxon have been drawn for the purpose of comparison. All the specimens examined were captured in the state of Paraná: Br. ortizi: Tibagi municipality, Canyon Quatelá (rocks) 16.XII.2004. Br. nitzulescui: Wenceslau Braz municipality, Dr Eno's small farm (forest) 22.II.2006, both species were captured with Falcão traps by the Maringá, Paraná, medical entomology team. Br. troglodytes: Ponta Grossa municipality, Vila Velha park 31.I.2006 (18:40 h), captured with a Shannon trap by Rosa-Cruz MF.

Etymology - With the name Brumptomyia angelae we wish to honor Mrs Angela Cristovalina Pernier dos Santos, DR Santos's wife, for her understanding of and respect for entomological study.



As occurs in some other species of Brumptomyia, the new taxon, Br. angelae sp. nov., has a gonostyle with two apical spines, the internal one implanted between the apical and the tubercle, the gonocoxite having stout and sclerotized setae in the apical region and the basal tuft of setae arranged in a longitudinal disposition and is thus more closely related to Br. ortizi Martins Silva & Falcão, 1971, Br. nitzulescui (Costa Lima, 1932), and Br. troglodytes (Lutz, 1922).

The new species differs from Br. ortizi in that in this latter species, the most proximal of the apical setae of the gonocoxite is located practically at the same level as the setae of the apical area of the basal tuft; the apex of the paramere clearly goes beyond the middle of the lateral lobe, and also because on the gonostyle the internal spine is implanted at the same level of the tubercle having the two external spines (Fig. 13).



It is possible to differentiate Br. angelae sp. nov. from Br. nitzulescui because in this latter, the stoutest setae of the basal tuft of the gonocoxite are in a more apical position and also because of the aspect of its paramere without the elbow in the pre-apical region of the ventral margin and the aedeagus is not bifid (Fig. 14).



Br. angelae sp. nov. can be distinguished from Br. troglodytes because this latter species presents parameres which narrow abruptly in the pre-apical region at the expense of the ventral margin, in such a way as to form a digitiform apical process (Fig. 15).

With the description of this new species, Brumptomyia is now seen to consist of 25 species, 15 of them in Atlantic domains, 11 of which in the state of Paraná: Br angelae sp. nov., Br. avellari (Costa Lima, 1932), Br. brumpti (Larrousse, 1920), Br. cardosoi (Barretto & Coutinho, 1941) Br. cunhai (Mangabeira, 1942), Br. galindoi (Fairchild & Hertig, 1947), Br. guimaraesi (Coutinho & Barretto, 1941), Br. mangabeirai (Barretto & Coutinho, 1941), Br. nitzulescui, Br. ortiz, and Br. troglodytes.
