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

RIBEIRO, H. & RAMOS, H. Cunha -- <strong>Research</strong> on the mosquitoes of Angola X
a relatively rare mosquito, C. insignis is probably widely distributed
also in Angola.
The adults in collection were caught at rest inside the tents of
our camp. C. insignis was never seen landing on man, which is in
accordance with its known zoophily.
7.3.4--Culex (Eumelanomyia) kingianus Edwards, 1922
New record for Angola.
MATERIAL EXAMINED. DALA TANDO, 2 larvae, 23.VIII. 1969; HUAMBO,
3, 12 larvae 14.IV.1970 and 23.VII-1.VIII. 1966.
TAXONOMIC NOTES. Our male agrees with the descriptions of
kingianus given by Edwards (8) and by Mattingly & Lips (42).
The larva tentatively attributed by Hopkins (24) to this species
and described by him (pp. 255-6) seems not to be, in fact, that of
kingianus. Anyhow, our larvae are in good accordance with the de-
scription given by Mattingly (42). In particular, it is to be noted that
all comb teeth on abdominal segment VIII are clearly scales and not
spines.
DISTRIBUTION AND BIOECOLOGICAL NOTES. Map 5 shows the only
two Angolan localities recorded for C. kingJanus.
Our male was reared from larva. All three larval biotopes recorded
for kingianus consisted in ground water. Two of them were small
pools at river margins with aquatic vegetation and moderately high
organic matter content. In the other instance, larvae bred in the
shallow margins of a small river with emergent and submerged
aquatic vegetation. The pH of the breeding water, measured in two
of the breeding places, was 5.6 and 6.4.
As to the associated species in the larval biotopes of kingianus,
C. duttoni and C. tigripes were recorded from two of these. An. demeilloni,
C. cinerellus, C. inconspicuosus, C. p. pipiens, C. p. quinquefasciatus,
C. toroensis, C. wigglesworthi and U. mashonaensis were also
recorded as associated larvae in one instance.
