Onthophagus amphinasus Arrow, 1931

Black, not shining, with the antennae bright yellow, thinly clothed with yellowish hair beneath, with extremely minute and inconspicuous setae upon the elytra. Small yellow spots are usually visible at the lateral margins of the 4th and 5th ventral sternites. Oval, highly convex, and deeply waisted. The head is flat and densely rugosely granular, with the ocular lobes bluntly angular externally, and the clypeus produced in the middle into a minute, not very sharp, process. There is a small tubercle of somewhat similar size at the middle of the hind margin of the head. The pronotum is densely covered with fine granules, which become larger and more shining towards the middle and base. The front angles are very blunt, the sides feebly rounded in front and feebly sinuate behind, and the base strongly rounded. The elytra are finely striate, the intervals flat and opaque, with minute scattered granules: the 7th stria is a little more strongly curved than the 6th. The pygidium is finely, densely, and rather confluently punctured. The metasternum is vertical in front and compressed to form a short process. The metasternal shield is very minutely and scantily punctured, and the sides of the metasternum are fairly strongly and closely punctured. The last ventral sternite is closely punctured. The two sexes are alike externally.
