Description: length: 8.7 mm; length of fore-body: 3.3; length of head: 0.8; breadth of head: 1.75; length of antenna: 2.3; length of pronotum: 1.25; breadth of pronotum: 1.05; length of elytron: 1; breadth of elytra: 1.15. Head black, pronotum red, elytra black, abdominal segments III-VI red, the following black; palpi, antennae and legs testaceous, the knees narrowly infuscate. Dorsal surfaces devoid of microsculpture except on and between basal keels of abdominal tergites. Pubescence long, pale, erect. Habitus: Fig. 17h.

Head strongly transverse; carina of post-ocular border salient, ending anteriad in a dentiform angle removed from posterior margin of eye; puncturation consisting of a cicle of 8 punctures on vertex, a few small ocular punctures, a transverse row of four large punctures before base and three punctures on each side on posterior margin. Pronotum cordiform, the sides slightly rounded to narrow base; lateral margin not bordered; disc with a pair of arcuate series of six punctures each, a cluster of eight punctures before that, 3-4 large lateral punctures, and a series of small punctures along lateral margins. Elytra small, scarcely broader than pronotum, the humeral angles completely obsolete, widest at posterior 2/3 rds; puncturation arranged in discrete transverse rows, the punctures of first row touching the row of long basal keels.

Female: sternite IX: Fig. 17vp.

This is a very distinctive species: the basic colour pattern is that of O. longipennis , O. bowringi and O. lewisius , but it is at once distinguished from those by its slender build and microptery.
