Genus Coptorhina (type species — C. africana) comprises 15 described species of black to
dark-brown, middle-size beetles (10-20 mm). Representatives of this genus are widely
distributed in Africa south of Sahara.
Coptorhines can be easily separated from other coprines by characteristic deep sinuation on
the lateral margin of elytra (and correspondingly widened metepisternon) and shape of
clypeus. Elytra are fused along lateral margins. When the beetle flies, elytra are not
opened but raised a little.
All coptorhines are assumed to feed on lamellar mushrooms
(Agaricaceae). Bidentate clypeus with wedge-shaped sinuation is used for cutting
a mushroom, especially for cutting off lamellae. Probably, the beetles cannot feed
on non-lamellate fungi.
