7 -- SYSTEMATIC ACCOUNT Genus Culex L. is a cosmopolitan <strong>on</strong>e, comprising near 600 described species and subspecies, about 150 <strong>of</strong> which occur in <strong>the</strong> Ethiopian Regi<strong>on</strong>. After <strong>the</strong> recent revisi<strong>on</strong>s by Sirivanakarn (29) (30), <strong>the</strong> Ethiopian species are thought to bel<strong>on</strong>g to seven subgenera: Lutzia Theo., Lasiosiph<strong>on</strong> Kirkpatrick, Barraudius Edws., Eumelanomyia Edws., Maillotia Theo, Culiciomyia Theo, and Culex L. Of <strong>the</strong>se subgenera, Lasiosiph<strong>on</strong> and Barraudius are represented <strong>on</strong>ly by <strong>on</strong>e and two species, respectively, c<strong>on</strong>fined to <strong>the</strong> nor<strong>the</strong>rnmost part <strong>of</strong> <strong>the</strong> Ethiopian Regi<strong>on</strong> (Sudanese Arid biotic z<strong>on</strong>e <strong>of</strong> Moreau). All <strong>the</strong> remainder five subgenera are widely distributed in <strong>Angola</strong> as well as in all <strong>the</strong> Africa South <strong>of</strong> Sahara. Basic descripti<strong>on</strong>s <strong>of</strong> <strong>the</strong> <strong>Angola</strong>n Culex are to be found mainly in F. V. Theobald (6), F. W. Edwards (8), G. H. E. Hopkins (24), Galliard (31), De Meill<strong>on</strong> & Lavoipierre (23), De Meill<strong>on</strong> et al. (28), De Meill<strong>on</strong> (33) and Brunhes et al. (14), though o<strong>the</strong>r tax<strong>on</strong>omic c<strong>on</strong>tributi<strong>on</strong>s will be cited under <strong>the</strong> corresp<strong>on</strong>ding taxa. 7.1--Subgenus I_,utzia Theobald, 190'3 This subgenus with str<strong>on</strong>g, predacious larvae is represented in <strong>Angola</strong>, as well as in all <strong>the</strong> Ethiopian Regi<strong>on</strong>, by a single generalized species. 7.1.1- Culex (Lutzia) tigripes Grandpr6 & Charmoy, 1900 The first published record <strong>of</strong> C. tigripes from <strong>Angola</strong> was that <strong>of</strong> M.

TAXONOMIC NOTES. C. tigripes shows a marked variati<strong>on</strong> through its range in <strong>Angola</strong>. Howewer, <strong>the</strong> comparis<strong>on</strong> <strong>of</strong> our material, both <strong>of</strong> adults and larvae, with <strong>the</strong> series in <strong>the</strong> British Museum (Nat. Hist.) c<strong>on</strong>firmed <strong>the</strong> infrasubspecific nature <strong>of</strong> this variati<strong>on</strong>. DISTRIBUTION. As it can be seen <strong>on</strong> Map 4, C. tigripes is a fairly generalized species also in <strong>Angola</strong>. BIOEOOLOGICAL NOTES. Larval tigripes was recorded from 104 different breeding places, 64 (61.5 per cent) <strong>of</strong> which were ground water, 28 (27 per cent) were artificial c<strong>on</strong>tainers and 12 (11,5 per cent) were 52 Estud., Ens. e Doc.- 134
