Tripteroides Giles, 1904

ADULTS ‒ Ornate mosquitoes with bright blue or silver band of scales anteriorly on head, silvery scales on thoracic pleura and one or all femora with silvery spots on anterior surface; head with 1‒3 ocular setae (usually 2) on either side; maxillary palpus very short in both sexes, < 0.2 length of proboscis; scutum with narrow piliform scales; dorsocentral and prescutellar setae usually present; mesopostnotum bare; pleural scaling sometimes reduced, subspiracular scales often absent; wing veins with narrow to moderately broad scales, broader on veins R2 and R3; tibiae and tarsi entirely dark-scaled; hindungues of males always paired; abdominal terga with lateral silvery spots or bands (except in some Tp. distigma). FEMALE GENITALIA – Postgenital lobe with shallow apical emargination; insula with 2‒8 marginal setae (usually 3‒5) and 1‒10 basolateral setae on each side; Oriental species usually with 1 spermathecal capsule, Australasian species with 3 (except Tp. littlechildi). MALE GENITALIA – Usually small and often retracted; gonostylus usually short and stout, expanded distally in some species; lateral plate of aedeagus with apical tergal process, projecting sternolaterad and usually ribbed or spiculate. LARVAE – Subgeneric characters not evident at present, Mabinii and Nitidoventer Groups distinguished as follows. Mabinii Group (1 species): Maxilla with exceptionally long apical tooth; hypostomal suture incomplete, not reaching posterior tentorial pit; seta 15-C inserted far posterior near collar; setae 6-M and 7-T single, very stout and rigid; seta 14-I‒VI minute or absent. Nitidoventer Group (Tripteroides sensu stricto): Maxilla with short apical tooth and typical maxillary brush; hypostomal suture complete to posterior tentorial pit; seta 15-C inserted far posterior near collar; seta 14-I‒VI strongly developed. PUPAE – Seta 1-CT very long, stout, conspicuous; seta 1-I strongly developed. See genus Tripteroides.
