Thorax .

Wing. With dark scales on all veins and without a minute basal spot of white scales on costa; cell R2 2.2 length of R2+3. Halter . With dark scales. Legs ( Fig. 30 A). Coxae with patches of white scales; white knee­spot absent on forefemur, present on mid­ and hindfemora; forefemur anteriorly with a narrow, white longitudinal stripe on ventral surface in basal 0.38; midfemur with a large white spot on anterior surface about 0.60 from base; hindfemur anteriorly with a broad white longitudinal stripe in basal 0.57 that widens 0.24 from base; foretibia anteriorly dark, with a basal white band; mid­ and hindtibiae all dark; foretarsomere 1 with basal 0.16 white on dorsal surface; foretarsomere 2 with basal 0.40 white on dorsal surface; midtarsomere 1 with basal 0.34 white on dorsal surface; midtarsomere 2 with basal 0.40 white on dorsal surface; midtarsomere 3 with basal 0.35 white on dorsal surface; hindtarsus with a basal white band on tarsomeres 1­4, the ratio of length of white band on dorsal surface to the total length of tarsomere is 0.30, 0.36, 0.46, and 0.50; hindtarsomere 5 all white; fore­ and midlegs with tarsal claws equal, all toothed; hindleg with tarsal claws equal, both simple. Abdomen. Tergum I with white scales on laterotergite; terga II­VII each with a basal white band and basolateral white spots not connecting with basal white band; sterna III­VII each with a basal white band; segment VIII completely retracted. MALE, PUPA and LARVA. Unknown. TYPE DATA . Holotype female (MEP Acc. 808/ Matahara, 18­I­68 , No. 1131), KENYA , 18­I­1968 . Deposited in Division of Vector Borne Diseases, Ministry of Health, Nairobi, Kenya [ DVBD ]. DISTRIBUTION. This species is presently known only from the Type locality Matahara = Mataara ( 0° 54' S , 36° 53' E ), Central Region of Kenya . TAXONOMIC DISCUSSION. Aedes sampi is a member of the simpsoni group. It has the scutum with an anteromedial white spot of broad scales, scutellum with broad white scales on all lobes and hindtarsomere 4 with a basal white band, and can thus be easily distinguished from all other species of the simpsoni group except Ae . subargenteus Edwards. Aedes sampi is extremely similar to Ae. subargenteus with which it has been confused and misidentified, but can be distinguished from Ae . subargenteus by: (1) the hindfemur anteriorly with a broad white stripe in basal 0.57; and (2) the hindtarsomere 5 all white. In Ae . subargenteus , the hindfemur anteriorly has basal 0.33­0.40 white, and has a large white spot about 0.67 from base (the white spot not connecting with the basal white area), and the hindtarsomere 5 has basal 0.40­0.67 white on dorsal surface.
