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> o[ <strong>Angola</strong> -- X<br />

species most <strong>of</strong>ten recorded as associates were An. cydippis (in 5 breeding<br />

places), C. annulioris (4), C. univittatus (3) and An. argenteolobatus,<br />

An. squamosus, C. dutt<strong>on</strong>i and C. tigripes (2, each).<br />

C. argenteopunctatus kingi is known to be mainly a zoophilic mosquito,<br />

though it may bite man in <strong>the</strong> outside (35).<br />

7.5.4- Culex (Culex) aurantapex jinjaensis Edwards, 1941<br />

New record for <strong>Angola</strong> <strong>of</strong> both <strong>the</strong> species and subspecies.<br />

MATERIAL EXAMINED. LOMBE RIVER (W <strong>of</strong> Malanje), 1 $, 3 $<br />

plus 6 larvae, II-1970; CALAI, 1 larva, 30.XI.1%5.<br />

TAXONOMIC NOTES. <strong>Angola</strong>n adult and larval specimens agree quite<br />

well with <strong>the</strong> descripti<strong>on</strong>s <strong>of</strong> var. finjaensis <strong>of</strong> Edwards (8).<br />

According to Hopkins (24), larvae <strong>of</strong> <strong>the</strong> type form are indistin-<br />

guishable from those <strong>of</strong> var. jinjaensis. Larvae from <strong>the</strong> Lombe River,<br />

bowever, are surely attributable to <strong>the</strong> Uganda-Zambia form, to which<br />

quite probably also bel<strong>on</strong>g <strong>the</strong> larva from Calai.<br />

According to <strong>the</strong> available evidence in <strong>Angola</strong>, larvae <strong>of</strong> jinjaensis<br />

can be separated from those <strong>of</strong> C. annulioris, C. bitaeniorhynchus and<br />

C. ethiopicus if <strong>on</strong>e takes into account <strong>the</strong> chactotaxy <strong>of</strong> abdominal<br />

seg. VIII (see larval key).<br />

DISTRIBUTION. Map 8 shows <strong>the</strong> <strong>on</strong>ly two <strong>Angola</strong>n localities known<br />

for finjaensis.<br />

BIOEOOLOGICAL NOTES. Two breeding places were recorded for<br />

jinjaensis: a pool at <strong>the</strong> edge <strong>of</strong> <strong>the</strong> Cubango River and <strong>the</strong> margins <strong>of</strong><br />

Lombe River. In both instances <strong>the</strong> water was clean and limpid, <strong>on</strong>ly<br />

shaded by emergent grasses. In <strong>the</strong> first <strong>of</strong> <strong>the</strong> larval biotopes, <strong>the</strong> pH<br />

<strong>of</strong> <strong>the</strong> breeding water was 6.5.<br />

C. poicilipes was an associated species in both instances, while An.<br />

coustani, C. simps<strong>on</strong>i (form A) and Ficalbia mal/eyti were recorded<br />
