来自大英博物馆的属于该物种的 fci-rinle 的前胸突间长大于宽，后端呈半圆形边缘，尖端锐利；前胸的后角也包围肩膀。 possMy，它应该被称为 Pmso# riotus。该物种是一个变异且分布广泛的物种，因为在英国阿鲁斯昆有两种来自罗伊克湾（澳大利亚西北部）的物种，一种来自库埃（西澳大利亚），另一种来自南澳大利亚博物馆的帕拉奇尔纳（南澳大利亚）。这些尺寸范围为 3 至 4 毫米，鞘翅上的后斑在尺寸和强度上有很大差异（在帕拉奇哈标本上，它们不规则地相连）；下表面的部分或多或少被深深地浸染。前胸部有非常细小的柔毛，很容易被忽视，巴利并没有消除。雄性的前胫骨比其他胫骨更长更薄，腹部有一个小而浅的根尖下压痕，而不是一个大的中央凹。
A fci-rinle, sent as belonging to this species, from the British Museum, has the intercoxsl process of the prosternmn longer than wide, with its posterior end semicircdarly emarginatje and the tips acute; the hind angles of the prothorax also embrace the shoulders. It should, possMy, have been referred to Pmso# riotus. The species is a variable and widely distributed one, as there are two ixnniplcs froin Roeb~ ick Bay (North-Western Australia) in the British Aluscuin, one froin Cue (Western Australia) nnd another from Parachilna (South Australia) in the South Anstralian Museum. These range in size from 3 to 4 mm., and have the postinedian spots on the elytra varying considerably in size and intensity (on the Parachiha specimen they are irregularly conjoined); parts of the under-surface are more or lcss deeply infuscated. The prothorax has very minute pubescence that could be easily overlooked and was not iiieiitioned by Baly. In the male the front tibiae are mnch longer and thinner than the others, and the abdomen has a small and shallow subapical impression instead of a large fovea.
