description: <i>Austrothaumalea queenslandensis</i> n.sp. Fig. 6 <b>Type material</b>. HOLOTYPE <b>?</b> "AUST: N.QLD: 400 m /Bellenden Ker N.P. / Kearneys Falls / 23.iv.1994 / B.J. Sinclair "; " HOLOTYPE / Austrothaumalea /queenslandensis /Sinclair [dissected]" (AMS). PARATYPES: <b>Queensland</b>: 2 <b>!!</b>, Mt. Windsor Tableland, 1000 m, creek, 16°26'S 145°12'E, 16.iv.1994, B.J. Sinclair (AMS). <b>Recognition</b>. This species is similar in colouration to <i>A. zentae</i> but is distinguished by its shorter paramere and pair of apical teeth-like projections on the gonocoxal plate. <b>Description</b>. <i>Wing length</i> 1.8–1.9 mm. <i>Coloration</i>: Head dull, dark brown. Thorax brownish-orange, somewhat shiny; legs pale yellow, becoming darker on apical tarsal segments; halter knob dark; abdomen dull greyish-brown, including pleural membrane; terminalia pale brown. <i>Wing</i> infuscate, darker along apical margin, especially at cell r 1+2; wing base pale, especially along wing folding; R+R 1 +R 1+2 with macrotrichia along entire length, remaining veins bare; R 2 situated towards apex of R 1; bend in R 3 sharply defined; R 3 and R 4+5 parallel toward wing margin; CuA with short basal appendage. <i>Male abdominal sternites</i> 1 and 2 not examined; 3–6 rectangular, sparsely setose; sternite 7 reduced to narrow, rectangular sclerite; sternite 8 membranous. <i>Male terminalia</i> (Fig. 6): Epandrium broadly trapezoidal from ventral aspect; posterior margin somewhat uneven with pair of small, round lateral knobs; lacking pointed posterolateral processes. Hypandrium broad, with deep median U-shaped cleft, nearly one-half width of base of gonostylus. Gonocoxite long, gradually tapering. Gonostylus long, curved strongly before mid-length; gradually tapering to blunt tip; apical half lacking setulae. Parameres fused to form long tube, slightly arched from lateral aspect; subequal in length to gonocoxites. Gonocoxal plate Y-shaped, secondarily fused to ventral surface of hypandrium; posterolateral corners with pair of tooth-like processes. <b>Distribution</b>. This represents the most northerly described species of thaumaleid recorded in Australia, collected at an altitude of 400 m or above. <b>Etymology</b>. Named for its restriction to the northern tablelands of Queensland. <b>Remarks</b>. The small pointed, knob-like lateral projections on the gonocoxal plate are very similar to <i>A. macalpinei</i> (not shown in Theischinger [1986, fig. 39]).
