Only five females and eleven males of C. simpsoni form A were
caught in nature, all the remainder adult specimens being laboratoryreared.
One of the females was caught when biting man in the open,
at sunset. Two unfed females and eight males were caught early morning
at rest in earth-holes and rock-holes near simpsoni breeding sites.
The other two females and three males were caught resting inside
human habitation, in the afternoon, one of them freshly fed.
As to the bioecology of each one of the forms A and B of C.
simpsoni, it is worth to note that all the records of brackish and salt
water biotopes concern only form A. In relation to this is the occurrence
of larval form A, and not of form B, in association with some
halophilic mosquito species, namely Ae. natronius, An. azevedoi, An.
listeri and C. thalassius. Inversely, some other species, such as C. decens
and U. /usca, were found only in association with larvae of form B.
Lastly, the breeding waters with the highest temperatures (and, quite
probably. also the lowest ones)seem to concern only form A, this
being related to the occurrence of this form of larval simpsoni in arid
biomes. All our data on adult C. simpsoni are attributable to form A.
7.5.24--Culex (Culex) telesilla De Meillon & Lavoipierre, 1945
C. telesilla was known from Angola only through the larval records
by Gindara (10) (11), in 1956, from Capelongo (= Folgares) and Luso
(= Moxico).
