  Type data:

   Holotype ANIC ♂ (coll: light trap, 15.iii.1961, K.L. Harley), Ingham, Queensland.

Introduction

This species was grouped by Löcker et.al. (2006) with O. gracilis Löcker and O. hirsutus Löcker as the "gracilis group" on the basis of the following shared features: dark tubercles contrasting with brighter coloured veins; fork of Pcu+A1 distinctly basad of centre of clavus; aedeagus configuration, i.e., phallotheca with a long, slightly curved spine arising left lateral at apex, a smaller curved spine arising ventrally about midlength, and in one species a long slender spine arising dorsolaterally at apex; flagellum unarmed. O. hamatus is found across the top end of the Northern Territory and Queensland down to the Central Mackay coast and north across Torres Strait to Saibai Island, off the southern coastline of Papua New Guinea.
