Aneugmenus coronatus (Klug, 1818)

Aneugmenus coronatus

Differences of opinion exist as to the colouration of males of Aneugmenus coronatus and as to how common they are.

Females have the clypeus and apical tergite marked with white and pale yellow respectively. Edges of the pronotum may also be pale yellow-marked as may be the front coxae. The head is polished and lacks puncturation (punctured in padi and with tubercles on fuerstenbergensis). The occipital carina at the back of the head reaches to the top of the eyes.

Larvae feed on ferns including lady fern, male fern and bracken.
