Sporadic cases of tegumentary leishmaniasis have occurred in Timóteo, Minas Gerais State, basically among the rural population. In order to study the region's sand fly population, New Jersey light traps were set in seven different neighborhoods. Specimens were gathered from June through October 1994, December 1994, and January through March 1995, with a total of 3,240 hours per trap. A total of 4,396 sand flies were captured, distributed among two genera and twenty species: Brumptomyia cunhai, Brumptomyia nitzulescui, Lutzomyia (Nyssomyia) whitmani, Lutzomyia (Nyssomyia) intermedia, Lutzomyia quinquefer, Lutzomyia lenti, Lutzomyia (Pintomyia) fischeri, Lutzomyia migonei, Lutzomyia sallesi, Lutzomyia termitophila, Lutzomyia aragaoi, Lutzomyia borgmeieri, Lutzomyia (Psathyromyia) lutziana, Lutzomyia (Sciopemyia) sordellii, Lutzomyia (Pintomyia) pessoai, Lutzomyia (Trichopygomyia) longispina, Lutzomyia misionensis, Lutzomyia (Psychodopygus) davisi, Lutzomyia lanei, Lutzomyia (Pressatia) sp. The species L. (N.) whitmani was the most frequent, with 52.12% of the total, followed by L. (N.) intermedia with 34.10%, and both may be involved in transmission of tegumentary leishmaniasis in the region.
