Corynoptera gladiota Mohrig, 2004 [Mohrig (2004): 162, fig. 29 a – c].

Comments. The species is characterized by rather long and rough flagellomeres, a 3 segmented palpus with 1 bristle on the basal segment, a nearly comb-like row of bristles at the apex of the fore tibia, rather long hairs on the scutum, the hypopygium with short sparse hairs at the ventral base and the inner margin of the short gonocoxites, gonostylus as long as the gonocoxites, with 3 short apical spines and a longer spine on a broad base somewhat below the middle of the inner side. It belongs to the genus Corynoptera within the C. parvula species group sensu Menzel & Mohrig (2000). It is conspecific with Corynoptera gladiota Mohrig from Papua New Guinea. The tibial organ is more strongly comb-like than in specimens from Papua New Guinea.

Distribution. Rather common on Hawaiian Islands; Papua New Guinea.
