DISTRIBUTION AND BIOECOLOGICAL NOTES. C. rubinotus is one
of the most widely distributed 12u,,nelanomyia in the Ethiopian Region.
This is probably also the case in Angola, though at present it is known
there from only theree localities (Map 5).
The Cabinda specimen was a gravid female caught at rest on bush,
near the airport of the town. The 29 females from Luando River
were caught biting man in the afternoon (17.15-17.45) during larval
collecting (larvae of rubinotus not found) in the shallow overflown
grassy margins of the river, near Quimbango, in the wooded savanna
biome ((>). In this area, man was insistently bitten by C. rubinotus,
Ae. argenteopunctatus, An. wellcomei ugandae, An. cydippis
and M. uniformis, the first two being true pests.
As far as we know, this marked anthropophily (and exophagy) of
C. rubinotus had only been recorded by Hamon (37), in the Bobo
Dioulasso area.
7.3.8 Culex (Eumelanomyia) wigglesworthi Edwards, 1941
New record for Angola.
MATERIAL EXAMINED. DALA TANDO, 8 larvae, 23.VIII. 1969.
TAXONOMIC NOTES. Angolan larvae agree with the descriptions
given by De Meillon et al. (28) and by Hopkins (24). The siphonal
index in our eight mounted whole larvae ranged from 7.1 to 8.3
(mean 7.5).
DISTRIBUTION AND BIOECOLOGICAL NOTES. C. wigglesworthi seems
to be mainly a West African mosquito, to which Subregion belongs
the only known Angolan locality for this species (Maps 3 and 5).
Larvae of C. wigglesvorthi bred in a small ground pool at the
edge of a river in the Dala Tando humid forest of the Scarpment
Zone. The breeding water was turbid, dark, foul water with many
decaying leaves and vegetable debris.
Larval An. demeilloni, C. cinerellus, C. kingianus, C. tigripes and
U. mashonaensis were associated with wigglesworthi in the only An-
golan breeding place recorded for this species (Fig. 3).
