I wonder if this is a female of Ctenoscelis coeus (Perty, 1832) or C. acanthopus (Germar, 1824)?

Thank you, Claude. Indeed, a male of a moderate size, 69 mm.

This is a male of Ctenoscelis coeus, the female has a narrower pronotum and a thinner 3rd antennal article. The pronotum of acanthopus is much more transverse. Here after a pair of coeus.

OK, thank you, Francesco. To me, the punctation in the center looked confusingly fine, leaving glabrous areas on both sides of the central line.

Having a punctured pronotal disc, it should be acanthopus...
