Aedes cumminsii (Theobald, 1903)




Etymology: Stephenson Lyle Cummin

Aedes cumminsi is widely spread across the African continent, south of the Sahara Desert, and comprises the most common of all five species comprising the Dentatus Group in South Africa. Aedes cumminsi has one valid subspeciesssp. mediopunctatus (Theobald)which was originally described from Ashanti in Ghana. This taxon has been placed into synonymy with and reelevated from synonymy with Ae. cumminsi several times, suggesting that further studies are needed to establish its taxonomic status.

Type locality: Bahr-el-Ghazal, Central Africa [South Sudan]

Type depository: Natural History Museum, London, England, United Kingdom (NHMUK)

ADULT (illustrated): Head: Proboscis entirely dark-scaled. Thorax: Scutum indistinctly marked; scutellum with narrow yellow scales. Post- and sub-spiracular scale patches present. Legs: Ti-III with apical yellow spot. 

LARVA (not illustrated): Head: Integument spiculate. Terminal abdominal segments: Comb with spine-like comb scales; seta 1-S small, inserted basal to distal-most of c. 14 pecten; pecten spines  closely-spaced basally, 3 distal-most widely-spaced; siphon index ≥4; c. 6 precratal setae; tiny chitinous plates on integument of larval thorax and abdomen.

Ae. cumminsi COI: KU187000, KU187000




The eggs are deposited in floodplain depressions as well as poorly drained depression in grasslands called “dambos”, and larvae have been collected in temporary turbid water poos at the edges of marshes. Rain that floods the site tends to hatch an entire cohort of eggs, so this species occurs in larger numbers after heavy rains, and adults may be absent between flooding events.


Surprisingly little is known on the biology of Ae. cumminsii. The females feed preferentially on cattle, but also attack man. Like other members of the subgenus, Ae. cumminsii is a floodwater mosquito, depositing its eggs in the soil of depressions above the current water line in anticipation of future flooding.
