"Castro (1959 (1960), p. 175) first pointed out that this species should be placed in the genus Haemagogus, not Aedes, but erroneously synonymized it under leucomelas Lutz, a name that was preoccupied, and the taxon had been renamed leucocelaenus by Dyar & Shannon (1924). The species continued to be included in Aedes (e.g., Carcavallo & Martínez 1968) until 1972 when Zavortink transferred it to Haemagogus, subgenus Conopostegus." (Mitchell & Darsie, 1985).

Disease relations: Haemagogus leucocelaenus is considered the primary vector of yellow fever virus (YFV) in wild environments in South America. The risk of YFV transmission to humans by the sylvan Haemagogus leucocelaenus was associated with forest-rural-urban interfaces and green patches within the cities that harbor nonhuman primates in Brazil (Cunha et al., 2020; Sacchetto, 2020).

The larvae of Haemagogus leucocelaenus breed in phytotelmata and tree holes located at high altitudes (Obholz et al., 2020). It has been reported the temporal and spatial occurrence of Haemagogus leucocelaenus in the wild-periurban fringe using ovitraps in the locality of Puerto Iguazú, Misiones, Argentina (Siches et al., 2021). It has also been confirmed the habitat plasticity of the species and it has been established the aptitude of artificial containers as a methodology in monitoring studies (Siches et al., 2021).
