ResumoIntroduction. This work aimed to study the community structure of sandflies, making known the richness, abundance and monthly frequency of the species in focus of transmission of leishmaniasis. Materials and methods . The study was conducted in Bom Jardim and Santa Maria rural villages, situated on the edge of a tropical rain forest infested by these insects in the municipality of Sao Jose de Ribamar-MA, Brazil. The phlebotomine were captured with light traps CDC in ten homes for one year, once a month, from 18:00 pm to 6:00 am. Results . We collected 1,378 individuals of sixteen sand flies species. The capture effort was higher in Bom Jardim (0.61 specimens/hour/trap) than Santa Maria (0.35). The sand flies peridomiciliary prevailed (86.1%) and the rainy season (77%). Five species were considered constants (occurring in more than 50% of samples), five, accessory (25% and 50%), and six accidental (<25%). The most abundant species were L. longipalpis (59.7%) and L. whitmani (28%). The permutation analysis demonstrated the difference between the species composition of the villages and no separation between the intradomicile and peridomicile of each village. The species that most contributed to the dissimilarity between the light traps of the two villages were L. longipalpis , L. whitmani and L. antunesi , contributing with 63.4% of the variation among groups. Conclusion . The high richness and abundance of species and the presence of competent vectors throughout the year and around houses justifying the occurrence of leishmaniasis cases reported in the area.
