Material examined. Holotype: 3/ 62 AR NSW 0.25km S jctn Tubrabucca & Omadale Brook Rds, 31:54S 151:23E Stewarts Brook S[tate] F[orest] 1290m ( NPWS Survey) 4 Feb–9Apr 1993 M. Grey & G. Cassis/ K264047/ ( AMS).

Description (male only). Length: male 4mm. Shape: body elongate-ovate and moderately arched, length 1. 7 x width, length 2. 2 x height. Body and appendages black. Dorsal surfaces shining, without microreticulation but evenly micropunctate (punctures not distinguishable <20x magnification).

Head: frontoclypeus with sparse fine punctures, frontoclypeal suture weak, base of clypeal area strongly depressed; antennae c. 0.4x body length; antennomeres 9–10 length = width.

Thorax: pronotum finely and sparsely punctured on disc and base, intervals 2– 5 x puncture diameters, strongly punctured laterally and apically; hypomeron entirely shallowly transversely wrinkled; elytral striae 1–8 complete, striae 4–8 feebly impressed; stria 9 reduced to basal third of elytra; punctures of striae 1–8 separated by 1–3 puncture diameters; punctures of basal half stria 3 separated by 2.5–3.5 diameters; apical strial punctures larger than basal; interstrial punctures minute but dense; apices of elytra with obtuse apical tooth; metaventrite femoral plate broad with sinuate posterior margin.

Abdomen: ventrites I–IV strongly microreticulate, ventrite V shining weakly microreticulate; ventrites moderately strongly and closely punctured, with short recumbent setae; first ventrite with shallowly arcuate femoral plate, c. 0.4x length of ventrite at this point; penis shallowly and gradually curved in lateral view, with slightly angulate apex in dorsal view, apex of flagellum visible, but not protruding in lateral view.

Distribution. Only known from the type locality, Stewarts Brook State Forest, on the north-western plateau of the Barrington Tops massif, central eastern New South Wales. This locality is appximately 480 km north-east of the nearest location for C. nobilis and separated from it by the broad and deep Hunter Valley ( Fig. 25), a well-known biogeographical barrier (Crisp et al. 1999). The specimen was collected in a pitfall trap. Grasstufting by CAMR on 13 December 2007 in Eucalyptus pauciflora woodland at 1370m, 8km northeast of the type locality, failed to find this species.

Etymology. From the local placename, Tubrabucca (a variant of tabrabucca: a ceremionial dance ground in the local Wiradjuri language, Reed 1967), a noun in apposition.
