Frons unevenly punctate, with areas of coalesced thickening and zones of differing relief; a gently arcuate/bow-shaped thickening on the brow adjoining vertex. Labrum coppery orange to red, and in proximal part largely impuncate and devoid of hairs. Pronotum largely punctate with limited development of transverse striae, somewhat flattened laterally, with relatively straight, gently curved sides, and two weak, obliquely elongate foveae along each side. Apical abdominal ventrite with a strong median carina in female (but obscure or absent in male) and its apex bidentate with a deep concave incision. Differs from C. mastersii in being concolourous and brassy blackish on ventral side, and from C. perroni in lacking a prominent dense patch of long pale hairs below upper elytral margin (on epipleural segment adjoining the metepimeron).
A widely distributed pan-Australian species. Known on northern Eyre Peninsula by dead salt lake specimens collected by P. Hudson, three from a lake in the western part and three from one on the eastern side.

The first breeding record presented here is an adult that I reared from a pupa in a dead branch of Nealie Wattle Acacia rigens collected c. 40 km NNE Renmark in Chowilla Regional Reserve. The elytra were damaged during emergence and their foveae are obscure but still discernable. Apart from this, it is a good match to intact adult specimens, including features of the apical abdominal ventrite.
This larval host species record is supported by a Chrysobothris larva, again from a dead branch of A. rigens. The latter was found much further SE in the Murray mallee Region (MU) in the Bakara area, where several adult C. saundersii were collected by M.A. Hura, including two observed on Acacia rigens stems.
