This species was placed in synonymy with Anopheles evansae by Brèthes (1926c) and resurrected as a valid species by Faran (1980). Older literature wich dealt with evansae could have been referring to either species (Mitchell & Darsie, 1985).
Disease relations: It has been found naturally infected with Plasmodium, without However, it is rarely found within the home and rarely feeds on humans, so, in general, it is not considered a primary vector of malaria and could only be of importance when its population density increases (Linthicum, 1988).

Larvae are raised in clear waters of small, half-shaded, or sunny streams; they are found along the banks with stream pastures, and also in quiet pools of streams and in rain wells with pastures. Females seem not to be attracted to humans, so they are not found in the intra-home (Rozeboom 1941). Adults are abundant in the peri-domicile and in the intra-domicile (Horsfall 1955). Females were captured in forest edges, marshy areas where cattle graze.
