RIBEIR0, H. & RAMOS. H. Cunha -- <str<strong>on</strong>g>Research</str<strong>on</strong>g> o. <strong>the</strong> <strong>mosquitoes</strong> <strong>of</strong> A.gola -- X<br />
rated from C. univittalus also by <strong>the</strong> shape and denticulati<strong>on</strong> <strong>of</strong> pecten<br />
spines, as it was presumed by Mattingly & Lips (42) and c<strong>on</strong>firmed by<br />
Someren (80) (p. l 1). On <strong>the</strong> o<strong>the</strong>r hand, <strong>the</strong> antennae <strong>of</strong> zombaensis are<br />
darkened throughout also in <strong>Angola</strong>n specimens, while <strong>the</strong> antennae <strong>of</strong><br />
<strong>the</strong>ileri and uivittatus are infuscate <strong>on</strong>ly at base and bey<strong>on</strong>d tuft, a<br />
difference already pointed out by Ovazza et al. (81).<br />
DISTRIBUTION. C. zombaensis is widely distributed throughout East<br />
Africa. In <strong>Angola</strong>, according to <strong>the</strong> available informati<strong>on</strong> (Map 14), it<br />
would seem that this mosquito is mainly associated with Mountain and<br />
Highland biomes (cf. Map 3). Anyhow, all <strong>the</strong> six <strong>Angola</strong>n localities<br />
known for C. zombaensis are at altitudes from about 900 to 1,700 meters.<br />
BIOEOOLOGICAL NOTES. All our adults specimens were reared in <strong>the</strong><br />
camp laboratory.<br />
4 breeding places <strong>of</strong> C. aombaensis were recorded: two niches in <strong>the</strong><br />
margins <strong>of</strong> slow-flowing rivers (<strong>on</strong>e <strong>of</strong> <strong>the</strong>m with much Pistia sp.), a p<strong>on</strong>d<br />
and a borrow-pit. The pH <strong>of</strong> <strong>the</strong> breeding water was 6.8 in <strong>on</strong>e instance,<br />
while <strong>on</strong> o<strong>the</strong>r larval biotope <strong>the</strong> organic matter c<strong>on</strong>tent was presumably<br />
high owing to <strong>the</strong> presence <strong>of</strong> many decaying vegetable debris. Larvae<br />
<strong>of</strong> <strong>the</strong> following species were also found as associates <strong>of</strong> C. aombaensis:<br />
Anopheles coustani s. str. and Culex antennatus (twice each), and An.<br />
funestus, An. gambiae, An. squamosus and C. univittatus (<strong>on</strong>ce). A typical<br />
larval biotope <strong>of</strong> C. zombaensis is shown in Fig. 14.<br />
C. zombaensis is not known to bite man.<br />
