AUSTRALASIAN, ORIENTAL & PALEARCTIC REGIONS
Generic abbreviation: Tr.
Type species: Runchomyia philippinensis Giles
Etymology: “tri-, L. (Gr. treis, trion) three; ptero-, pteron, Gr. feather, wing; -eides, Gr. (L. -aides) like, resembling, having the form of” (Harbach 2018c).
The genus Tripteroides is a large, complex assemblage of 122 species, subdivided into five subgenera - Polylepidomyia (19 species), Rachionotomyia (14 species), Rachisoura (28 species), Tricholeptomyia (9 species) and Tripteroides (52 species). Species are distributed from India to Japan, and south to Australia including the islands of southeast Asia and the South Pacific. The species comprising the genus are highly diverse, and the relationships among Tripteroides and Trichoproposon species remain unresolved as many characters overlap. The taxonomic status of this genus urgently needs revision.

Tripteroides larvae rest upside-down on the substrate of the container, looking up through the water in search of food. While most species feed on detritus, the larvae of the subgenus Rachisoura posess enlarged, spiny maxillae and are predacious. In jungle-dependent species, Tripteroides immatures are common in the water collections in standing, fallen and discarded phytotelma habitats—bamboo and tree stumps, leaf axils (Allocasia, Colocasia, Nipa, Pandanus), ginger flower bracts, tree holes, snail shells, coconut shells and husks, Nepethes pitcher plants and fallen leaves. Immatures of the Australian endemic Tp. tasmaniensis (Strickland) solely inhabit rock holes and others, e.g., Tp. aranoides (Theobald), are collected in artificial containers.
Little is known of the biting preferences of most Tripteroides species. In the Australian Region, several species (e.g., Tp. solomonis Edwards) are strongly anthropophilic, entering houses to bite, whereas in the Oriental region, only Tp. aranoides is known to attack people. In Tp. aranoides mating is initiated in flight, and copulation takes place on vertical surfaces. The first oogenesis is autogenous, but subsequent egg batches require a blood meal. Females oviposit on the wing, with females flicking their abdomens and thrusting individual eggs into the larval habitats. Tripteroides bambusa (Yamada) are susceptible to infection with Getah virus.
