RIBEIRO, H. & RAMOS, H. Cunha -- <strong>Research</strong> on the mosquitoes of Angola -- X
7.5.2--Culex (Culex) antennatus (Becker, 1903)
C. antennatus was firstly recorded from Angola (Huambo) by Grin-
data (lo) (11) and later by Worth & Paterson (12), from Caxito, and by
one of us (34) (50), from Lobito and Luanda.

TAX,OOMIC NOTES. Angelan antennatus agrees quite well with
known descriptions, namely those by Edwards (8), Hopkins (24) and Larivire
& Abonnenc (51). Males are easily identifiable through the examination
of terrainalia. Females need to be carefully separated from those
of univittatus and of C. pipiens pipiens, which may be better accomplished
with the aid of our key. The difficulties found in the separation of
antennatus larvae from those of decens, invidiosus, telesilla, trifoliatus
and univittatus are well known. The larval key here proposed, however,
will permit a correct diagnosis at least of the great majority of the
specimens. As always, the association of specimens of different phases
and sexes will be of great help, and it must be kept in mind that univittatus
is an usual mosquito in the larval biotopes of antennatus, at least
in Angola (see below).
DISTRIBUTION. The general distribution of C. antennatus is a quite
interesting one, the species being widely distributed throughout the Tropical
Africa with an extension into the south-eastern Mediterranean
Subregion of the Palaearctic (Egypt, Palestine, and Iran). In Angola, it
