Explanation of Notes
a Aedes furcifer adult has abdominal terga II–VII with pale scales scattered on both apicolateral and dorsomedian areas. Aedes cordellieri Huang , a closely related species to Ae. furcifer , can easily be distinguished by having abdominal terga II–VII with yellowish scales scattered on apicolateral areas only and no scattered pale scales on dorsomedian areas.
b Aedes taylori, Ae. furcifer and Ae. cordellieri adults can be distinguished from other species by the following combination of shared characters: thorax with acrostichal, dorsocentral, prescutellar and lower mesepimeral setae well developed; paratergite with pale scales; scutellum with broad scales on all lobes; wing veins with white and dark broad scales intermixed dorsally; and, femora, tibiae and tarsomeres 1 sprinkled with white scales. The absence of any speckles on the abdominal terga is a reliable specific character for Ae. taylori to separate it from Ae. furcifer and Ae. cordellieri .
c Aedes luteocephalus adult can be distinguished from other species by the following combination of characters: scutum with a medianlongitudinal yellow stripe; scutellum with all broad white scales on lateral lobes; abdominal terga II–VI each with a basal pale band and basolateral white spots; hindtibia has basal 0.10 to 0.25 white stripe on ventral surface; hindtarsomere 3 with basal 0.50 to 0.80 white stripe; and, hindtarsomere 4 entirely dark. Aedes ruwenzori Haddow and Van Someren can be distinguished from Ae. luteocephalus by the scutellum having broad dark scales on the lateral lobes, and the hindfemur with 3 white patches on the anterior, median and apical areas.
d Aedes africanus adult differs from other species by the following combination of characters: scutum with short anterior medianlongitudinal white stripe, and with fossal white patch narrow at base along scutal margin; and, hindtarsomere 4 has basal 0.2–0.3 white stripe on ventral surface.
Ae. corneti Huang can be distinguished from Ae. africanus by the hindfemur having 3 white patches on the anterior surface.
e Aedes opok adult differs from other species by the following additional character: scutum with fossal white patch broad at base along scutal margin. Larval specimens of Ae. opok are not available for this work.
