Aedes (Ochlerotatus) taeniorhynchus (Wiedemann) 



Culex iaeniorhvnchus Wiedemann, 1821, Dipt. Exot., p. 43. 



ADULT FEMALE. — Medium sized to rather small species. Head: Proboscis 

 long, dark scaled, with a white ring near middle; palpi short, dark, white 

 scaled at tips. Occiput dorsally with a broad longitudinal stripe of golden- 

 yellow to pale golden-brown lanceolate scales, the stripe narrowed anteriorly 

 and projecting forward between the eyes; this broad median stripe bounded on 

 either side by a few dark scales, followed laterally by a large patch of broad 

 appressed white scales enclosing a small dark-scaled area. Erect forked scales 

 numerous, those on central portion of occiput pale. Thorax: Integument of 

 scutum dark-brown, clothed dorsally with narrow golden-brown scales becoming 

 dark-brown on lateral margins; the scales on the anterior margin, on prescutel- 

 lar space, and immediately above the wing bases pale yellow to nearly silvery 

 white. Posterior pronotum with narrow dark -brown scales. Abdomen: First 

 tergite dark scaled; remaining tergites dark scaled, with narrow basal white 

 bands dorsally and conspicuous white patches laterally; apices of the terminal 

 tergites with a few pale scales. Sternites white scaled basally, dark scaled or 

 speckled with white apically. Legs: Femora and tibiae dark brown to black 

 scaled, pale on inner surfaces; femora usually tipped with a few white scales. 

 Tarsi black; segments of hind tarsi each with a broad white basal ring, segment 

 5 occasionally entirely white; segments 1 to 3 of fore- and mid-tarsi with basal 

 rings narrower than those of hind tarsi; segments 4 and 5 of fore- and mid- 

 tarsi entirely dark. Wirjg: Scales narrow, dark. 



ADULT MALE. — Coloration similar to that of female, but with occiput usual- 

 ly rather indefinitely marked. TERMINALla (Fig. 113B). Lobes of nhith tergite 

 (IXT-L) about as broad as long, moderately sclerotized, separated by the 

 width of one lobe, each bearing several short stout setae. Tenth sternite (X-S) 

 prominent, sclerotized. Phallosome (Ph) a stout cylinder, rounded apically, 

 open ventrally, closed dorsally, lightly sclerotized. Claspette stein (CI-S) slen- 

 der, cylindrical, curved, pilose, extending a little beyond apex of basal lobe; 

 claspette filament (Cl-F) nearly as long and broad as stem, curved, tapering 

 to a point and bearing a prominent simple sharp retrorse projection medially. 

 Basistyle (Bs) about three and one-half times as long as broad, cylindrical, 

 rounded apically, clothed with large scales and numerous long setae; basal lobe 

 (B-L) a broadly conical projection having many slender setae on apex; apical 

 lobe absent. Dististyle (Ds) about half as long as basistyle, broadened medial- 

 ly, slender and curved apically; terminal claw (Ds-C) slender, curved, a little 

 more than one-fourth as long as dististyle. 



larva. (Fig. 114). — Head broader than long. Antenna less than half as 

 long as head, slightly curved, sparsely spined; antennal tuft small, double or 

 triple, inserted slightly before middle of shaft, not reaching tip. Head hairs: 

 Preantennal (A) short, multiple, barbed; lower (B) and upper (C) long, 

 single; postclypeal (d) small, branched; sutural (e), trans-sutural (f) and 

 supraorbital single. Upper lateral abdominal hairs on segments III to V with 

 three or more branches. Comb of eighth segment of numerous scales in a
