Explanation of Notes
a Ochlerotatus mediovittatus in the adult stage can be separated from the other members of the genera Aedes and Ochlerotatus in the Americas using various diagnostic characters, namely: scutum with a narrow medianlongitudinal white stripe; presence of a silver patch of scales or short line in the fossa and above the prealar knob but no patch of scales on or below the prealar knob; posterior pronotum with narrow, curved dark scales; paratergite, scutellar lobes and front of mesothoracic spiracle with broad, flat white scales; hindfemur with a long narrow white line on the anterior surface; hindtarsomeres with pale bands; and, abdominal segments 6–7 not flattened laterally unlike Ochlerotatus triseriatus (Say) (B. A. Harrison, unpublished information).
b Aedes albopictus , the Asian tiger mosquito, can be distinguished from related species by the presence of broad, flat white scales on the lateral margin of the scutum just before the level of wing root. When scutal markings are rubbed off, Ae. aegypti can be easily misidentified as Ae. albopictus . It can be distinguished by having two separate white scale patches on the mesepimeron whereas they are connected in Ae. albopictus .
