Trichocolletes avialis is a species of bee in the family Colletidae and the subfamily Colletinae. It is endemic to Australia. It was described in 2012 by Australian entomologists Michael Batley and Terry Houston.
Etymology The specific epithet avialis (Latin: 'out-of-the-way') refers to the remote collection sites of the two male type specimens.
Description The male holotype body length is 12.6 mm. The eyes are not hairy. Colouration is mainly black and dark brown to orange-brown, with white markings, broad silver metasomal bands, and orange hair.
Distribution and habitat The species occurs in arid areas of northern Australia. The type locality is 20 m east of Mount Madley, in the Kata Kata Hills, on the edge of the Little Sandy and Gibson Deserts, in Western Australia. A paratype male was also collected at 41 Mile Bore in the Northern Territory.
Behaviour The adults are flying mellivores.
