This study lists 32 species of sand flies, 1 of them belonging to the genus Brumptomyia and 31 to the genus Lutzomyia, distributed among the following subgenera: Psychodopygus (6), Nyssomyia (5), Pressatia (3), Evandromyia (2), Psathyromyia (2), Sciopemyia (2), Lutzomyia (1), Micropygomyia (1), Viannamyia (1), and the groups Oswaldoi (5) and Migonei (3). The sand flies were captured in the wild (forest) and in peridomicile (pigpen, hen house and stable) and intradomicile (bedroom) areas from 06:00 PM to 06:00 AM, once a month, for 4 years on the Island of São Luis, Maranhão. All species sampled were present in the forest. Among them, 16 were found in the peridomicile, while 11 were found inside the houses. A total of 22,581 specimens were captured, 65.1% of them in the peridomicile, 17.5% in the forest and 17.4% in the intradomicile. The most common species was Lutzomyia longipalpis (66.4% of the captured specimens), followed by Lutzomyia whitmani (24%) and Lutzomyia evandroi (5.9%). The remaining 29 species represented 3.7% of the total sample.
