T h o r a x ( Fig. 13 ). Pronotum, prescutum, scutum, scutellum and mediotergite brown, a narrow pale yellow stripe arising at the anterior margin of the prescutum, extending onto the scutum and terminating at the transverse suture. Pleurites largely pale yellowish brown with darker brown areas as follows; the whole of the anepisternum, the base of the katepisternum, the base of the meron and the whole of the anatergite. Legs with coxa, trochanter and base of femur pale yellowish brown, remainder of fore and mid leg darker greyish brown, tarsi of hind leg missing.

W i n g ( Fig. 12 ). Membrane largely greyish brown, pterostigma darker grey. Halter with stem dark grey, knob dark grey at the base, paling to white distally.

A b d o m e n ( Fig. 11 ). First tergite entirely greyish brown, tergites 2-7 greyish brown dorsally with lateral pale yellow patches. These lateral patches appear to be variable in size and are more extensive in the paratype than in the holotype. Sternites 2-4 greyish brown with broad subapical transverse pale yellow band, sternites 5-7 similarly patterned but with the transverse band apical in position. Eighth abdominal segment entirely greyish brown.

Tergite 9 with two faintly developed flat posterior lobes separated by a shallow quadrate notch. Outer gonostylus straight, distal third slightly broader. Inner gonostylus moderately curved and with pointed beak, a row of short serrations along the dorsal edge. Aedeagus, when viewed laterally, strongly arched at mid-length. Distal portion of adminiculum not expanded, distally truncate.

D i m e n s i o n s. Wing length 9.0 mm, body length (excluding antennae) 8.1 mm.

E t y m o l o g y. This species is dedicated to the Rowan family, particularly Lyn Rowan, for unending support and for helping to fund the first author’s Tasmanian survey work.
