( Figs 6 , 12 , 16 , 20 , 25)

Material examined. Holotype: 3/ Chalcolampra arthritica Lea, K. G. Sound / (MMS); paratypes (3): 23, 1Ƥ/ K. G. Sound/ (MMS).

Description. Length: male 3.5–4mm; female 5mm. Shape: body short-ovate and strongly arched, length 1.4–1.5x width, length 1.9–2.2x height. Colour: body reddish-brown to black, with faint greenish hue, appendages dark reddish-brown. Dorsal surfaces relatively dull, microreticulate throughout, reticulation coarser on elytra.

Head: frontoclypeus with small to large close punctures, frontoclypeal suture weak, base of clypeal area strongly depressed; antennae c. 0.5x (male) or c. 0.3x (female) body length; all antennomeres elongate, 9–10 length 1.4–1.6x width.

Thorax: pronotum closely and evenly punctured, intervals 1.5– 3 x puncture diameters; hypomeron entirely shallowly transversely wrinkled; elytral striae 1–9 complete, striae 2–8 (female) or 2–9 (male) feebly impressed; punctures of striae 1–8 close, separated by 0.5–2 puncture diameters; punctures of basal half stria 3 separated by 1–3 diameters; apical strial punctures not enlarged; interstriae with scattered large punctures and more numerous minute punctures, latter obscured by microreticulation; apices of elytra with elongate acute apical tooth; metaventrite femoral plate triangular with posterior margin slightly convex.

Abdomen: ventrites shining, microreticulate but weakly so, especially ventrite V, moderately strongly and closely punctured, with short recumbent setae; first ventrite with semicircular femoral plate, half length of ventrite at this point; penis shallowly curved with thin apex in lateral view and rounded apex in dorsal view, flagellum not visible externally; female genitalia unknown (missing).

Distribution. Only known from the type locality, King George Sound, now Albany, south-west Western Australia. This area has significantly higher rainfall than the rest of the south-western bioregion.

Etymology. Named for the extinct indigenous language, Minang , local to the King George Sound area (Thieberger 1996): a noun in apposition.

Notes. One specimen was identified by Lea as Chalcolampra arthritica Lea, 1903 , a species now in genus Ethomela Lea, 1916 ( Reid 2006a) . This is not a type specimen and was simply misidentified.
