RIBEIRO, H. & RAMOS, H. Cunha -- <str<strong>on</strong>g>Research</str<strong>on</strong>g> <strong>on</strong> <strong>the</strong> <strong>mosquitoes</strong> <strong>of</strong> <strong>Angola</strong> X<br />
MATERIAL EXAMINED. BOCOIO, 1 9, 4 larvae, 7-10.IX.1970; EBANGA,<br />
1 9, 21 larvae, 17-19.IX.1970.<br />
TAXJONOMIC NOTES. Our material is in quite good agreement with<br />
<strong>the</strong> descripti<strong>on</strong>s by Theobald (6), Edwards (8), Knight (38), and Hopkins<br />
(24). In particular, larvae show that <strong>Angola</strong>n salisburiensis is <strong>of</strong> <strong>the</strong><br />
type form and not <strong>of</strong> ssp. naudeanus <strong>of</strong> Muspratt (39), as: (a) <strong>the</strong> comb<br />
c<strong>on</strong>sists <strong>on</strong>ly <strong>of</strong> scales; (b) <strong>the</strong> pecten teeth are straight and have 2-4<br />
basal denticles; (c) head seta C is much more delicate than B and is <strong>on</strong>ly<br />
about half <strong>the</strong> length <strong>of</strong> this <strong>on</strong>e.<br />
DISTRIBUTION AND BI. OECOLOGICAL NOTES. Map 5 shows <strong>the</strong> <strong>on</strong>ly<br />
two known <strong>Angola</strong>n localities for C. salisburiensis. However, as salisburiensis<br />
seems to bc <strong>the</strong> most generalized Ethiopian member <strong>of</strong> <strong>the</strong> subgenus,<br />
it is expected to bc widely distributed also in <strong>Angola</strong>.<br />
Our females wcrc reared from larvae. Eight larval biotopcs <strong>of</strong> C.<br />
salisburiensis wcrc recorded by <strong>the</strong> writers. In six instances, larvae bred<br />
al<strong>on</strong>g <strong>the</strong> shallow margins <strong>of</strong> small rivers, while <strong>the</strong> o<strong>the</strong>r two breeding<br />
places wcrc rock-pools at river edges. The breeding water was always<br />
limpid and with aquatic vegetati<strong>on</strong>, usually emergent. The pH <strong>of</strong> <strong>the</strong><br />
water, measured in six instances, ranged from 5.4 to 6.4 (mcan, 5.8).<br />
C. annulioris, An. coustani, An. demeill<strong>on</strong>i and An. l<strong>on</strong>gipalpis were<br />
<strong>the</strong> most frequently associated <strong>mosquitoes</strong>, o<strong>the</strong>r Anophelines (ardensis,<br />
[unestus and ru[ipes) and Culex (decens, ethiopicus, p. pipiens, tigripes<br />
and univittatus) being also recorded from <strong>the</strong> breeding places <strong>of</strong> salisburiensis.<br />
C. salisburiensis seems to be a zo<strong>of</strong>ilic mosquito as it was never<br />
caught by us biting man nor inside human habitati<strong>on</strong>s.<br />
7.3 -- Subgenus Eumelanomyia Theobald, 190'91<br />
Adopting <strong>the</strong> viewpoints <strong>of</strong> Sirivanakarn (29) (30), <strong>the</strong> new editi<strong>on</strong> <strong>of</strong><br />
<strong>the</strong> World <strong>Catalog</strong> by Knight & St<strong>on</strong>e (23) lists 64 species under subgenus<br />
Eumelanomyia Theo., most <strong>of</strong> <strong>the</strong>m Ethiopian, but also Oriental and a<br />
few Australasian. Edwards' subgenus Mochthogenes is now c<strong>on</strong>sidered<br />
as no more than a group <strong>of</strong> species within subgenus Eumelanomyia Theo.,<br />
while Neoculex Dyar is now thought to be mainly Australasian and also<br />
