Diagnosis

This new species is similar to Z. cambodianus in having the PPP with the apical margin rounded in lateral view. However, it can be distinguished from the latter by having the hind wing with five distal hamuli (four in Z. cambodianus ).

Etymology

The specific epithet is derived from the hamuli (‘ hamulus ’ is Latin for ‘small hook’), because members of this species have five distal hamuli on the hind wing.
