Anopheles namibiensis Coetzee, 1984

TYPE LOCALITY: Mahongo , Kavango District, Namibia .

Described and named as a new species based on morphological characters of the adults, larva and pupa, and differences in chromosomal inversion banding patterns compared with An. ziemanni Grünberg, 1902 .

DESCRIPTION:

Wing length: 5.0 mm.

Wing ( Fig. 5 ): Subcostal and preapical pale spots present, small; apical pale fringe spot rarely extending beyond wing tip of R 3.

Maxillary palpus: Shaggy, with four pale bands.

Legs:Apex of foretibia and base of foretarsomere 1 always dark. Apex of hindtibia, base of hindtarsomere 1 and apices of hindtarsomeres 1 and 2 with pale spots at most 3 times as wide as diameter of the tarsomere; hindtarsomeres 4 and 5 pale, 0.5 of hindtarsomere 3 pale.

LARVAL HABITAT: Vegetated pools and swamps in forested areas around Yaoundé, Cameroon ( Manga et al. 1997).

ADULT BIOLOGY: Females were collected in cattle enclosures at the type locality ( Coetzee 1984). In Cameroon, human landing catches carried out in Simbock village, Yaoundé, yielded 10 An. namibiensis ( Manga et al. 1997) . The records of An. namibiensis from Cameroon ( Ayala et al. 2009) using pyrethrum spray catches in houses show it to be present in the western highlands, Adamaoua highlands and the central plateau near Yaoundé.

DISTRIBUTION: Mahongo in Kavango District, northern Namibia; Yaoundé, Cameroon. The Tanzanian distribution record given in Irish et al. (2020) is incorrect as Mahongo is in Namibia, not Tanzania.
