Cydistomyia sp. A

Material examined. QLD: 1♀, 2 km SE Paluma , 914 m, rainforest, u. v. light, Jan., E. Britton , ( ANIC) .

A slender, 13 mm, brown species represented by a single female appears to be distinct, although close to pseudoardens and fergusoni . It is not named pending collection of further specimens, but may be distinguished from C. pseudoardens by the wider frons, wider more triangulate callus with extension barely reaching middle of frons, darker antennal style, pale apical bands on abdominal tergites overlaid with short white hairs but not expanded to form median white haired triangles, darker more uniformly chocolate brown venter with prominent pale apical bands on sternites and overlaid with sparse white hairs, paler less chocolate brown colouration of wing veins and stigma, uniformly brown costal cell, and darker greyish brown scutum with more clearly demarcated dorsocentra1 and lateral vittae. The species is distinguished from C. fergusoni by the narrower callus not extending full width of frons at base, absence of ocellar tubercle, presence of plump palps with dense black hairs, absence of median white-haired apical triangles on abdominal tergites, and costal cell of wing uniformly suffused with brown.
