Aneugmenus temporalis (Thomson, 1871)

Aneugmenus temporalis

Aneugmenus temporalis is black bodied in both sexes, though the pronotum may be edged narrowly with white. The occipital carina does not extend more than half way up the eye. The distance between cenchri is less than the width of a cenchrus, the cenchri themselves being elongate (3:1). In males the hind femora are black.

Larvae feed on bracken.
