May-Uc, E., H. A. Hernández-Arana & E. A. Rebollar-Téllez. 2011. Distribución de flebotominos(Diptera: Psychodidae) en Quintana Roo, México. Acta Zoológica Mexicana (n. s.), 27(2): 273-289. RESUMEN. Se llevó a cabo un estudio faunístico en el estado de Quintana Roo para conocer la distribución, riqueza y abundancia de los flebotominos. Se observó una gran variabilidad del promedio de especies y abundancia dentro y entre tres diferentes zonas (sur, centro y norte) en el estado. La mayor abundancia y riqueza se registró en la zona norte, en la zona centro y sur se capturaron igual número de especies, y la zona centro tuvo la menor abundancia. En cada zona fueron diferentes las especies dominantes, aunque, Lutzomyia shannoni y Lutzomyia cruciata se registraron dentro de las más dominantes distribuidas en las tres zonas. Entre las especies dominantes que se presentan en el estado se encuentran aquellas que son incriminadas como vectores de leishmaniasis en la Península de Yucatán. Los factores ambientales que se presentan en el estado son reflejados en las abundancias encontradas en las diferentes zonas de Quintana Roo.

A faunistic study was carried out to gain insight into the distribution, species richness and abundance of sandflies in Quintana Roo, Mexico. There was a great intra-and interregional variability in mean species richness and abundance in Quintana Roo. The northern region appeared to have the highest species richness and abundance, followed by the central and southern regions, which exhibited an equal richness between them. Also, the central region showed the lowest sandfly abundance. Each region showed a rather distinctive dominant species composition, although two species, Lutzomyia shannoni and Lutzomyia cruciata, were among the most abundant in all three regions. In fact, some of the most abundant speciesare suspected vectors of leishmaniasis at the Yucatan Peninsula.

Two new species of phlebotomine sand flies from Quintana Roo, Mexico are described and illustrated following the classification proposal of Galati (2003). Pintomyia (Pifanomyia) itza Ibáñez-Bernal, May-Uc and Rebollar-Tellez sp. nov., is described based on four male specimens, whereas Psathyromyia (Psathyromyia) maya Ibáñez-Bernal, May-Uc and Rebollar-Tellez sp. nov., is described based on seven female specimens. Pintomyia (Pif.) itza clearly belongs to the verrucarum series, and is the only species of this series known to occur outside South America. Psathyromyia (Psa.) maya belongs to the lanei series which was previously known only from Brazil and Paraguay.
