Introduction

The origin of the type material was presumed to be the Wet Tropics bioregion of North Queensland where F.P. Dodd, who collected the material, did most of his collecting (Monteith 1991). However, Constant (2018) reports on three additional specimens (2 males, 1 female), which are not part of the type series, but collected by F.P. Dodd at Townsville in the northern extremity of the North Brigalow Belt bioregion where he resided before moving to Kuranda in the Wet Tropics. It is therefore possible that the type locality is in the more southern bioregion. The species epithet marginatus (adjective, Latin) means ʻmarginedʼ and refers to the darkened costal and apical margins of the tegmina.

Constant (2018) provided numerous photographs of specimens in their natural habitat and listed host plants in six plant families. He also published evidence that areas of O. marginata habitat on Magnetic Island and around Townsville which were devastated in 2011 by Cyclone Yasi were recolonised by the species within five years.

Diagnosis

Head, pronotum, mesonotum, face, rostrum, and legs black; abdomen and sternum sanguineous; lateral areas of sternum and lateral and apical segmental margins of abdomen beneath black; apical area of abdomen cretaceously tomentose; tegmina castaneous, with scattered small paler spots, the costal and apical margins broadly and the claval margin narrowly black; wings piceous, the venation black; head (including eyes) reaching the anterior lateral angles of the pronotum; face broad, finely granulose, its lateral angle broadly obtusely prominent; clypeus smooth, not carinate; vertex of head almost as long as pronotum; mesonotum distinctly tricarinate. Long, excl. tegm., 6 mm; exp. tegm. 18 mm. (Distant 1906).

This species can be recognized by the following combination of characters: (1) hind wings without orange marking; (2) pro- and mesofemora and -tibiae largely black-brown; (3) anal tube of male spatulate, constricted at basal ⅓; (4) centroventral part of gonostyli with narrow and strongly elongated process that is sinuate basally and hooked apically; (5) laterodorsal part of gonostyli with narrow and strongly elongated process that is strongly curved posteroventrally; (6) rather small size: 6–8 mm (Constant 2018).
