C. annulioris, C. cinerellus, C. kingianus, C. salisburiensis, C. simpsoni,
C. thalassius, C. theileri, C. toroensis, C. tri[oliatus, C. tritaeniorhyn-
chus and E. chrysogaster were found only once in association with
piplens s.s.
Only one male and five females (ratio of anterior fork to its stem
3.9-5.0) were caught as pipiens s.s. adults. From these, one unfed
female from Cherugema and the male, from Mogfimedes, were caught
at rest in crabholes (no larvae found). Another unfed female (wing
ratio 5.0) was caught when biting man outdoors, at Mogfimedes. The
remainder three females were caught when resting on walls inside
human habitation, at about 9 h a.m., two of them gorged (one from
Cubal and the other from Huambo) and the other unfed.
Unfortunately, the nature of the blood in the stomach of the two
gorged females was not investigated nor tests for anautogeny and
eurigamy were carried out. In spite of this, however, the above remarks
on the larval and adult bioecology of the Angolan pipiens s.s.,
besides showing a marked contrast with quinque[asciatus (see below)
strongly suggest the absence of the form molestus from Angola. In
fact, unlike quinque[asciatus, the only other Angolan form of the
pipiens complex seems to be clearly a non man-associated, zoophilic
mosquito unable to breed in the sewage system or in surface waters
contamined by human excreta as ,well as in containers related to domestic
activities, rarely entering houses and biting man only exceptionally.
7.5.19 -- Culex (Culex) piplens quinquefasciatus Say, 1823
As it was said under C. p. pipiens, we maintain here the nomenclature
of Stone, Knight & Starcke (17), and of Knight & Stone (23),
though the evidence available to us is clearly in desagreement with
a subspecific treatment of the two forms of the pipiens complex known
to occur in Angola.
C. p. quinque/asciatus was firstly recorded from Angola (Luanda)
by Colago (9), in 1952, as C. /atigans Wied. . Other published
locality records are those by Gfndara (10) (11) from Lobito (9), Capelongo,
Cuando and Moxico (L), and by Worth & Paterson (12) from
Cabinda and Mogmedes (adults, sexes not mentioned). Other papers
dealing with quinque/asciatus in Angola are those by Ribeiro &
