Description (male, female). Rather large, slightly elongate, predominantly dull tawny fly, with almost unmarked wing; most parts pruinescent and non-shining.

Coloration (clean specimens which have not passed through alcohol). Head, in large part, tawny-orange; postfrons with darker tawny-brown ocellar region, largely covered with greyish pruinescence, and paler grey to yellowish-pruinescent orbital margin; face and cheeks paler than rest of head, yellowish with whitish pruinescence. Antenna largely dark brown; more basal parts of segment 3 tawny. Prelabrum yellow to grey-brown; palpus tawny-yellow basally, greybrown on distal third or more. Thorax dorsally tawny-orange; mesoscutum broadly creamy grey-pruinescent on lateral margins, with narrower pale-pruinescent dorsocentral stripe interrupted at suture and between the two dorsocentral bristles, and very narrow less distinct median pale-pruinescent stripe; humeral callus pale-pruinescent, except on ventral margin near spiracle; scutellum without pale-pruinescent margins; pleura tawny-orange, very generally covered with dense pale greyish to yellowish pruinescence, mesopleuron thus without any exposed tawny areas. Legs largely pale tawny-orange; all femora broadly brown-black at apices; tibiae all brown-black apically, mid and hind tibiae also with brown basal zone; tarsal segment 3 partly brown, segments 4 and 5 usually darker brown. Wing: membrane slightly tinged with yellow-brown, less intensely so than in Luta luteipennis ; subcostal cell with broad yellow-brown blotch restricted to part of cell near end of subcosta; veins tawny; anterior and discal crossveins without trace of darker pigmentation. Halter yellow. Abdomen tawny, without distinct darker markings; tergites 1 to 4 covered with fine rather dense greyish pruinescence; tergite 5, in contrast, smooth and glossy, pruinescent only near lateral margins; in male sternite 8 and in female tergite 6 glossy like tergite 5.

Head slightly higher than long, slightly angularly produced anteriorly so that face is oblique in profile; cheek 0.43–0.50 as high as eye, with numerous fine setulae not reduced to single series anteriorly; face with very slightly
