Original description [1]

TRICHOPTILUS (?) INCLITUS, sp. nov.

♂, ♀. 23-26 mm. Head fuscous, closely irrorated with ochreous. Palpi dark fuscous. Antennae ochreous fuscous. Thorax fuscous grey, irrorated with ferruginous fuscous. Abdomen ochreous fuscous, longitudinally streaked with grey, black and fuscous. Tibiae alternately banded light ochreous, fuscous and dark fuscous, anterior pair specially thickened with scales on origin of spurs. Forewings cleft from before middle, segments linear, ferruginous ochreous with dark fuscous, darker toward hindmargin; an ochreous white spot on costa at 5/6. Cilia smoky-grey, on costa narrowly based with fuscous ochreous, darker toward apex; 2nd segment with cilia of darker shade toward base. Hindwings cleft first from before 1/3, secondly from base, segments linear, ferruginous fuscous. Cilia of 1st and 2nd segments smoky grey; 3rd segment darker ferruginous with black cilia.

This appears much the largest species of the genus taken in Australia. Mr. Boyd of Toowoomba found the first specimen and Dr. T. L. Bancroft found a second near Brisbane which unfortunately got damaged by ants.
