BIOECOLOGICAL NOTES. All our adult specimens of C. inconspicuosus
were laboratory-reared.
16 larval biotopes were recorded for inconspicuosus, consisting of
river margins (16), small ground pools (4), rock pools (3), small
streams (2) and one large permanent pool. Aquatic vegetation was abundant
in larger breeding places while fallen leaves were usually present
in smaller ones. As a rule, appreciable additional shade was provided by
surrounding vegetation. The breeding water was usually clean, with
a pH, measured in five instances, of 5.4-6.9 (mean 5.9).
The species of mosquito larvae associated with C. inconspicuosus
in the 16 breeding places for this species were, by decreasing order
of frequency: An. coustani (in 17 of them), An. demeilloni (6), F. mimomyaformis
(4), An. funestus (3), An. obscurus, C. cinerellus, C. ingrami,
C. perfidiosus, and U. mashonaensis (2, each) and, recorded
only once, An. cinctus, An. gambiae, An. nili Congo form, An.
rivulorum, An. r. rufipes, C. kingianus, C. simpsoni, C. tigripes, C. univittatus,
C. weschei gediensis and U. balfouri.
Fig. 2 shows a larval biotope of C. inconspicuosus.
C. inconspicuosus is a widely distributed and relatively common
species in Angola. It seems to be a zoophilic mosquito, as it was never
seen by the writers either landing on man or resting inside human habitation.
C. inconspicuosus was also reported by Hamon (37) as not bitting
man in the Bobo Dioulasso area.
7.3.3--Culex (Eumelanomyia) insignis (Carter, 1911)
C. insignis was previously recorded from Angola (Maquela do
Zombo) only by Worth & Paterson (12), in 1961.
