Type series. Holotype ♂, by original designation. QUEENSLAND. Chillagoe [17.15°S, 144.52°E]; in SAM [examined].

Additional material examined. 1♂, Chillagoe , in ANIC register number 25-039401-147 ; 1♂, Chillagoe , Clark, in ANIC register number 25-039401-148 ; 1♂, 6 km SE of Chillagoe , 26.xi.1981, J. Balderson, in ANIC register number 25-039401-149 .

Diagnosis of males. Body 21–22 mm long. Colour pale reddish brown. Lamella of antennomere 4 approximately three-quarters length of lamella of antennomere 5. Maxillary palp with apical palpomere broad, with an elongate, depressed dull area on upper surface. Pronotum with greatest width 1.6x mid length; anterior margin without defined margins towards anterior angles, with a narrow, raised posterior margin most clearly defined across the middle. Parameres ( Fig. 9 ) with apices transverse, dorsal margin sinuate concavely, ventral margin concave arcuate and apically broadened in lateral view, apical third very constricted in ventral view.

Distribution ( Fig. 17 ). Known only from the type locality and nearby; the area has a Köppen-Geiger climate of Aw (savanna).
