Cornetius Huang, 2005

Subgenus Cornetius is characterised by the following combinations of characters, which distinguishes the subgenus from all other generic-level taxa of Aedini [characters that provide a polythetic diagnosis of the subgenus in the phylogeny of Reinert et al. (2009) are indicated with an asterisk (*)]. ADULTS ‒ Dorsum of head with broad decumbent scales, erect scales *on occiput and vertex; *interocular setae absent; mesal surface of antennal pedicel with patch of broad pale scales; maxillary palpus of male about as long as proboscis, palpomeres 2‒5 with pale basal bands (incomplete ventrally on palpomeres 4 and 5), palpomeres 4 and 5 very short (total length shorter than length of palpomere 3), *down­turned, palpomere 4 slightly swollen, with a few short stiff setae at apex, *palpomere 5 ≤ 0.55 length of palpomere 4; maxillary palpus of female about 0.25 length of proboscis, with pale band at bases of palpomeres 2 and 3, palpomere 4 minute; *acrostichal and *dorsocentral areas of scutum each with stripe of pale scales posteriorly, acrostichal setae absent; scutal fossa with contrasting pale scales in large patch; paratergite with broad pale scales; scutellum with broad pale scales on all lobes; postspiracular setae present; subspiracular area with broad pale scales; *upper prealar scales and *lower prealar scales present [latter absent according to Huang, 2005]; *upper mesokatepisternal setae absent; *lower mesepimeral setae present; postprocoxal membrane without scales; *anterior surface of midfemur with pale stripe from base to or near apex; *hindtibia with pale-scaled areas; basal pale bands on at least hindtarsomeres 1‒3; *abdominal segment VII dorsoventrally flattened. FEMALE GENITALIA ‒ *Posterior margin of sternum VIII with median emargination separating sublateral lobes; *posterior margin of postgenital lobe straight; cerci short and broad, *distal part gently oblique, *cercal scales present; insula as long as or slightly longer than broad, with tuberculi, without setae; upper vaginal sclerite present; lower vaginal sclerite absent; 3 spermathecal capsules, one slightly larger. MALE [no-lexiicon]GENITALIA[/no-lexicon] ‒ *Lateral lobes on posterior margin of tergum IX close together; sternum IX with setae; gonostylus elongate, rather flat, slightly expanded just beyond middle, narrow and curved toward apex; gonostylar claw stout, *inserted subapically some distance from apex of gonostylus; c1aspette well developed, with numerous setae; aedeagus strongly toothed; *paraproct with sternal arm; cercal setae absent. LARVAE ‒ Seta 4-C well developed, single, simple, inserted closer to seta 6-C than to seta 5-C, inserted anteromesad of 6-C; seta 12-I absent; *seta 6-II as long as seta 6-III; *seta 1-VIII single; seta 2-VIII distant from seta 1; comb scales in single row; seta 1-S single, long, inserted distal and anterior to pecten spines; *seta 3-X branched; ventral brush (seta 4-X) with 5 pairs of setae on grid, without precratal setae. PUPAE ‒ Seta 6-CT single, long, stout; *seta 7-CT much shorter than 6-CT; *seta 3-II thinner than seta 1-II; *seta 3-III shorter than seta 5-III; *seta 5-V shorter than following tergum; *seta 2-VI inserted lateral to seta 1-VI; seta 9-VI,VII single, long, stout, much longer and stouter than seta 9-I‒V; paddle margins with fringe of fine hair-like spicules, *apex with moderately deep emargination; seta 1-Pa *present, single and long.
