Research on the mosquitoes of Angola - Systematic Catalog of ...

RIBEIRO, H. & RAMOS, H. Cunha -- <strong>Research</strong> on the mosquitoes of Angola X
rivers Lombe, Cuanza and Cubango. 50 of the females were caught
when biting man in the open, at dusk (from 6.00 to 7.00 p.m.). Another
female was caught indoors, also landing on man, at 19.00. Finally,
one unfed female was caught at rest, in the outside, at about 18.30.
Thus, according to our experience, C. poicilipes must be regarded
as an important man-biting mosquito in the Angolan savannas, which
is in accordance with the findings of other Authors in other parts of
Africa (35) (37).
7.5.21--Culex (Culex) pruina pruina Theobald, 1901
New record for Angola.
MATERIAL EXAMINED. DALA TANDO, 3 9, 9 plus 2 larvae,
25-26.VIII. 1969.
TAXOIOMIC NOTES. In the Angolan larvae of the nominal subspecies
of C. pruina head seta d has 4 or 5 branches and, with the exception
of the more distal pair, subventral tufts of siphon have 6-10 branches
per tuft (mean about 8.5). The spiculation of the thorax and abdomen
seems to be strongly variable. Head seta e is bifid, and not single as
described by Hopkins (24), f has 3-6 branches and the lateral seta of
saddle is 3- or 4-branched. Other larval characters, as described by
Hopkins (op. cit.).
The adults, including the male terminalia, agree quite well with
known descriptions (74) (8).
For further taxonomic analysis, see also under subspecies eschirasi.
DISTRIBUTION. Map 17 shows the only Angolan locality known for
C. p. pruina, within the West African zoogeographical Subregion.
BIOEOOLOGICAL NOTES. Our adults of C. p. pruina were laboratory
reared. 2 larval biotopes of pruina s.s. were recorded: a sunlit rock-pool
with greenish water in the margins of the Capecha river, and a shaded
bamboo stump in a bamboo gallery forest remnant. In both instances
the breeding water was foul and turbid, with decaying vegetable debris
