During studies of the phlebotomine sand fly fauna of Campo Grande, State of Mato Grosso do Sul, Brazil, a new species was captured with CDC light trap and is described here. The new species resembles Lutzomyia lutziana (Costa Lima) and is named Lutzomyia campograndensis sp. n. after the type locality.

Material from light trap collections from Campo Grande, State of Mato Grosso do Sul, Brazil, was included on undescribed species of Lutzomyia França. The description of this new species is based on morphological characters proposed by the Cipa Group (1990) and Galati (1995). All measurements are given in mm. Figure in parentheses refer to means of all specimens measured.

Collection data and deposition of type material. Holotype male collected by AG Oliveira in Zé Pereira forest, municipality of Campo Grande, Mato Grosso do Sul, Brazil, on March 9th, 1999. Allotype female collected by AG Oliveira in Zé Pereira forest, on April 13th, 1999. Seventeen paratype males and ten paratypes females collected by AG Oliveira in Campo Grande were also examined: 13 males and six females were captured in Zé Pereira forest in the following dates: two males on February 23rd, 1999; one male on March 2nd, 1999; two males on March 16th, 1999; one male on April 13th, 1999; two males on August 10th, 1999; one male on August 17th, 1999; one male on September 9th, 1999; one male on September 28th, 1999; one male on December 7th, 1999; one male on January 3rd, 2000; one female on February 18th, 1999; one female on June 1st, 1999; one female on August 3rd, 1999; one female on September 28th, 1999; one female on December 14th, 1999 and one female on December 21st, 1999. Three males and two females were captured in the "Reserva Ecológica do Parque dos Poderes" on the following dates: one male on June 28th, 1999; one male on November 8th, 1999; one male on December 6th, 1999; one female on November 8th, 1999; one female on January 31st, 2000. Two females were captured in Chácara das Palmeiras, one on September 7th, 1999 and the other on January 5th, 2000. One male was captured in the Botanical Garden of Campo Grande on January 3rd, 2000. Holotype and allotype are deposited in the phlebotomine sand flies collection at the Centro de Pesquisas René Rachou, together with 19 paratypes (13 males and six females). One pair of paratypes each consisting of one male and one female, was donated to the collection of the Faculdade de Saúde Pública, Universidade de São Paulo, Brazil; Instituto Oswaldo Cruz, Rio de Janeiro, Brazil; Instituto Nacional de Pesquisas da Amazônia, Manaus, Brazil and Natural History Museum, London, United Kingdom.

Type locality: the municipality of Campo Grande, capital of the State of Mato Grosso do Sul (20o26'34''S; 54o38'47''W). Geographically located in the central portion of the state, occupying 2.3% of the total area. The predominant climate of Campo Grande, according to the classification of Kopper is of rainy tropical savanna, subtype AW, characterized by uneven annual distribution of rain, with one well defined rainy season between November and March. The annual medium temperature is around 23oC, the maximum being around 25oC in December and the minimum 18oC in June. The municipal district lies across two great geomorphologic areas: the plateaus arenitic-basaltic interior plateau of the westernborder of the Paraná River Basin. The urban area includes extensive areas of modified forest and of some primary remains, the latter in the Reserva Ecológica of the Parque dos Poderes and the Botanical Garden.










This species is very similar to Lutzomyia lutziana (Costa Lima). The male of the new species differs from L. lutzianahaving the tips of genital filaments dilated rather than slender. The female is also similar to L. lutziana. The female of the sand fly described as Phlebotomus sp. de Cayenne by Floch and Abonnenc (1945) is considered to be the female of L. lutziana (Forattini 1973, Leger et al. 1977, Martins et al. 1978), but the original drawing of Phlebotomus sp. de Cayenne shows that the common duct is longer than individual duct, in contrast with the drawing of the female of L. lutziana in Young and Duncan (1994). In the collection of Centro de Pesquisas René Rachou-Fiocruz we studied a male captured by Abonnenc in Cabassou, French Guiana and verified that this specimen is conspecific with our new species. We also examined two females of L. lutziana from Lassance (its type locality) and concluded that Phlebotomus sp. de Cayenne is not the female of L. lutziana. This material will be described later.

The taxonomic placement of the new species is doubtful. L. lutziana is placed in the subgenus Psathyromyia Barreto by Young and Duncan (1994), but they considered its status to be provisional. According to Galati (1995), L. lutzianabelongs to the genus Psathyromyia, subgenus Forattiniella Vargas, series lutziana. In this paper we prefer not to includeL. campograndensis in the subgenus Psathyromyia as the group characters in this subgenus clearly require redefinition.

Geographic distribution: the new species was captured in the western and northern regions of Brazil. Beside the type locality, Campo Grande, it has been found in Nioaque and Camapuã (Mato Grosso do Sul); Manaus (Amazonas); Caracaraí (Roraima); Macapá (Amapá) and Cabassou (French Guiana). Galati et al. (1996) also captured this species in the municipality of Corguinho, Mato Grosso do Sul.
