"The type locality of this species is Baradero, Buenos Aires (Knight & Stone 1977). Nyssorhynchus albitarsis formarly was believed to be distributed from Guatemala, Centrla America, south to Argentina, but Faran & Linthicum (1981) have reconized anothe species, Anopheles allopha (Peryassu 1921), for all of this range, except southern Brazil, southern Paraguay, Uruguay and Argentina to which albitarsis is now restricted." (Mitchell & Darsie, 1985).
Disease relations: The highest rates of experimental Plasmodium infection have been found in Nyssorhynchus aquasalis and Nyssorhynchus albitarsis (Rios-Velásquez et al. 2013), with the latter presenting higher biting indices (da Silva-Vasconcelos et al. 2002). Las Maloyas virus was isolated from specimens of Nyssorhynchus albitarsis between 1977 and 1980 in Corrientes Province (Mitchell et al., 1985). During the 1982-1983 outbreak in Argentina, strains of Western Equine Encephalitis virus were isolated from pools of Nyssorhynchus albitarsis (Mitchell et al., 1987).

Larvae and pupae of Anopheles albitarsis have been collected in large swamp marsh depressions with grasses, sunlight, pH between 5.50 and 6.79, together with larvae of Anopheles annulipalpis, Aedeomyia squamipennis, Culex idottus, Culex brethesi and species of Mansonia, Psorophora and Uranotaenia. Immature stages were also collected from puddles between rocks in river beds and roadside ditches.
