Since the last yellow fever (YF) outbreak was detected in Argentina in 2009, vector surveillance and studies of arbovirus infections are carried out intermittently specifically in areas where nonhuman primates of theAlouatta genus are present. We report in these areas of Corrientes province the detection of Haemagogus leucocelaenus (Dyar and Shannon) (Diptera: Culicidae) and Sabethes albiprivus (Theobald) (Diptera: Culicidae), both species involved in the forest YF cycle, and also the presence of Aedes albopictus (Skuse) in new areas in Argentina, which represents the southernmost citation for this species in South America. Aedes albopictus, a mosquito species native to Asia, was reported for the first time in Argentina in 1998, in Misiones province.Since then, no other report has indicated the extension of the distribution of this mosquito. This report shows the importance of performing continual entomological and arboviruses surveillance and highlights the impactthat could result from the expansion of Ae. albopictus across Argentina.
