Addenda to Hancock's description. Hancock's original description is accurate. Our measurements of the holotype are in accordance with Hancock's. Since description of O. pennatum is publicly available online (digitalized), we do not present full re-description of the species. Important is however to add certain characters to the description on which Hancock (1909) and other scholars did not pay attention at that time. Frontal costa short. Bifurcation of the frontal costa close to the fastigium, for about one diameter of lateral ocellus. Lateral ocelli between the eyes in the middle, below bifurcation of the frontal costa. Antennae 12-segmented. Antennae 1.8 times longer than fore femur, inserted between the lower margin of the compound eyes, mid segments ~2.5 times as long as wide. Facial carinae straight or slightly undulated, scutellum between them much wider than scapus. Dorsal margins of the antennal grooves between the lower fifth of the compound eyes width. Alae surpassing pronotal apex. Pulvilli of the hind tarsi with apical teeth. Ventral margin of hind tibiae with 8 outer and 6 inner spines.

Colouration. Body yellowish brown; tip of antennae dark brown to black; upper margin of pronotum (= median carina in lateral view) with 23 black dots; above the tegmina discus has five black spots in two rows, upper with two spots and lower with three spots; fore and mid tibiae with two pale brown rings, junction between tibiae and tarsi, as well as the apex of tarsi with dark bands; genicular teeth of hind femora dark brown; second segment of the hind tarsi and apex of third segments with black bands; claws of all legs dark brown; alae pale green with black tinge.
