The phlebotomine sand fly Lutzomyia evansi
is recorded in Mexico for the first time. This species is a suspected vector of Leishmania infantum
in other parts of its geographical range and was captured in a focus of American visceral leishmaniasis where the principal vector, Lu. longipalpis sensu lato
, was also found. The relative public health importance of the two species in the study area (Chiapas state, Southern Mexico) is discussed.
