Aneugmenus coronatus
Differences of opinion exist as to the colouration of males of this species and as to how common they are.
Females have the clypeus and apical tergite marked with white. Edges of the pronotum may also be white marked as may 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.
