RIBgIRO, H. & RAMOS, H. Cunha -- <strong>Research</strong> on the mosquitoes of At,gola -- X
7.5.16 -- Culex (Culex) perfidiosus Edwards, 1914
New record for Angola.
MATERIAL EXAMINED. DUNDO, 10 larvae, 19.VI11.1969; GUNGO,
3 larvae, 23.XI.1969. MUMBONDO, 2 larvae, 8.V.1970.
TAXONOMIC NOTES. All our larvae agree closely with the description
given by Hopkins (24). Head setae B and C are always trifid and the
mentum has 8-10 teeth, these characters distinguishing larval per/idiosus
from the larva of schwetzi described by Peters (44). For the separation
of the larvae of C. per/idiosus from those of C. pipiens forms, see the
larval key under 6.
DISTRIBUTION AND BIOECOLOGICAL NOTES. Map 16 shows the three
Angolan localities known for C. per/idiosus, all of them in Northern
Angola.
Six larval biotopcs of per[idiosus wcrc recorded by the writers: 4
rock-pools with decaying leaves and 2 rain-water ground pools, all of
them in forest. The pH of the breeding water, measured in a ground
pool under Laurisilva forest in the $carpmcnt, was 6.2.
Larvae of 13 other species were found in association with per[idiosus.
From these, C. decens, C. inconspicuosus, C. invidiosus, C. telesilla
and C. tigripes were recorded twice, while An. coustani, An. [unestus,
An. implexus, An. obscurus, An. rivulorum, C. trifoliatus and U. [usca
were found only once. Figs. 2 and 12 show typical larval biotopes of
C. perfidiosus.
As far as we know, perfidiosus has not been reported as biting man.
7.5.17- Culex (Culex) perfuscus Edwards, 1914
New record for Angola.
MATERIAL EXAlVIINED. SAURIMO, 1 , 10.IV. 1970.
TAXONOMIC NOTES. Our per[uscus female agree quite well with
known descriptions. It can be separated from female ornatothoracis
mainly by its entirely dark hind tibia and from female telesilla by its
shorter upper fork cell, which is only about two times as long as the stem.
