Key to male
Phrudoneura
from
Australia
and Melanesia
Phrudoneura
males are readily recognized by their abbreviated vein M, which ends in the membrane well before reaching the wing margin. This key to
Phrudoneura
should suffice for the species under consideration. However, there are undescribed species in the Papuan region where confirmation will require more care.
