Key to subfamilies and genera: females(with subgenera and species for genera with only one species in the country) 1 Maxillary palpus with 5 palpomeres and about as long as proboscis; scutellum evenly rounded with setae evenly distributed along border; abdominal sterna (and usually also terga) wholly or largely devoid of scales (except An. pulcherrimus, An. stephensi and species of the Hyrcanus Group); radial sector (vein Rs) with basal spur (subfamily Anophelinae).... Anopheles - Maxillary palpus with fewer than 5 palpomeres and distinctly shorter than proboscis; scutellum trilobed with setae in 3 distinct groups; abdominal sterna and terga covered with scales; vein Rs without basal spur (subfamily Culicinae)............... 2 2(1) Anal vein (1A) reaching wing margin at about level of fork of cubital vein (Cu); cell R 2 (anterior forked cell of radius) shorter than 0.5 length of radius-two-plus-three (R 2+3); wing membrane apparently without microtrichia, these visible only under high magnification; proboscis somewhat swollen apically; upper calypter bare; alula bare................................................................................................... Uranotaenia (Pseudoficalbia) unguiculata - Anal vein reaching wing margin well beyond fork of Cu; cell R 2 more than 0.5 length of vein R 2+3; wing microtrichia visible under low magnification; proboscis not swollen apically; upper calypter with setae or hair-like scales; alula with scales.... 3 3(2) Prespiracular setae present; wing with setae present ventrally at base of subcosta (Sc)......................... Culiseta ‒ Prespiracular setae absent; wing without setae ventrally at base of Sc............................................ 4 4(3) Postspiracular setae present............................................................................. 5 - Postspiracular setae absent.............................................................................. 6 5(4) Wing with very broad, asymmetrical scales; paratergite without scales; ungues (claws) of foreleg simple; abdominal tergum VIII with a row of teeth (comb); abdomen rounded and blunt apically; cerci short, hardly visible.............................................................................................. Mansonia (Mansonioides) uniformis - Wing with narrow scales, if broad then not conspicuously asymmetrical; paratergite with scales; ungues of foreleg toothed; abdominal tergum VIII without a row of teeth; abdomen generally pointed apically and cerci long (except subgenus Stegomyia)...................................................................................... Aedes 6(4) Length of maxillary palpus more than one-third (about 0.4) length of proboscis; scutum with a unique pattern of white scales on dark background; fore- and midtarsomere 1 longer than the remaining 4 tarsomeres combined; tarsomere 4 shorter than tarsomere 5.................................................................... Orthopodomyia pulcripalpis - Length of maxillary palpus less than one-third length of proboscis; scutum without such unique pattern; fore- and midtarsomere 1 shorter than tarsomeres 2–5 combined; tarsomere 4 longer than tarsomere 5..................................... 7 7(6) Scales of wing usually broad; hindtarsomere 1 distinctly shorter than hindtibia; ungues (claws) of hindleg large and conspicuous; pulvilli inconspicuous (seta-like).......................................... Coquillettidia (Coquillettidia) richiardii - Scales of wing usually narrow (except Cx. (Oculeomyia) bitaeniorhynchus); hindtarsomere 1 as long as or longer than hindtibia (except subgenus Barraudius); ungues of hindleg small and inconspicuous; pulvilli conspicuous (pad-like).......... Culex Key to subfamilies and genera: fourth-instar larvae(with subgenera and species for genera with only one species in the country) 1. Siphon absent; seta 1 palmate on some abdominal segments; comb absent; hypostomal sclerite of maxilla (‘cardo’ of Harbach & Knight 1980) bar-like (subfamily Anophelinae).................................................... Anopheles - Siphon present; abdominal seta 1 never palmate; comb present; hypostomal sclerite of maxilla broad and flat (subfamily Culicinae)........................................................................................... 2 2(1) Comb scales arising from lateral or dorsolateral plate on abdominal segment VIII; seta 1-C on small conical projection; hypostomal suture incomplete, not reaching posterior tentorial pit (PTP)......... Uranotaenia (Pseudoficalbia) unguiculata - Comb scales arising from unsclerotized integument; seta 1-C not on projection; hypostomal suture well developed, extending to PTP.............................................................................................. 3 3(2) Siphon attenuated and pointed, with saw for piercing plant tissues............................................... 4 - Siphon sub-cylindrical with blunt apex, not adapted for piercing plant tissues...................................... 5 4(3) Portion of antenna beyond setae 2,3-A (flagellar segment) very long and flexible; comb with 4–10 scales with apical spine...................................................................... Coquillettidia (Coquillettidia) richiardii - This portion of antenna much shorter and rigid; comb with 1–3 scales without apical spine................................................................................................... Mansonia (Mansonioides) uniformis 5(3) Sclerotized plates present on abdominal segments VII–VIII; siphon without pecten...........
