(Fig. 3)
Type material. Holotype: male (Fig. 3), E. Luzon, Aurora, Sierra Madre, 14 km S. of Dilalongan, Dapalan River, 50 m, 16°02.709’N 121°42.667’E, 11–12 II 2008, J.H. Lourens and K. Knoblich (IRSNB).
Etymology. The specific name is from the Latin brevis meaning “short” in reference to the comparatively short wings of this new species.
Measurements of types (in mm, 1 male). Length of body: 23.9; length of forewing: 29.7; width of forewing: 10.5; width of head including eyes: 6.7; width of pronotum: 8.5; wing span: 66.1.
Diagnosis. This and the next new species are closely allied to O. simonae but distinguished by the following characters: mesonotum with medial longitudinal fascia being narrow, narrower than sublateral marks on lateral sigilla; forewing barely tinged; forewing with infuscation much reduced; forewing with basal membrane being narrower and gray; timbal cover with anterior inner corner not angled; timbal cover with posterior inner corner being widely separated from posterior margin of tergite 2; both uncal lobes forming heart shape with their inner margins, which is longer than wide; uncal lobes with apex directed downward (anteriad) or laterad in ventral view.
Description of male (Fig. 3). Head ochraceous with following black marks: median spot enclosing ocelli, with its anterior end reaching frontoclypeal suture and posterior end reaching posterior margin of head; pair of spots on supra-antennal plates; three pairs of small spots between the median spot and compound eyes; pair of spots on anterolateral corners. Supra-antennal plates developed and produced anteriad. Distance between lateral ocelli and compound eyes slightly less than or about as long as twice the distance between lateral ocelli. Postclypeus barely swollen. Antenna ochraceous to dark brown. Ventral part of head light green to greenish ochraceous with black marks. Postclypeus laterally margined and with medial longitudinal fascia on about posterior half, small V-shaped mark on about anterior one-third and fasciae along anterior three to four transverse grooves. Anteclypeus with central spot. Rostrum black apically; passing posterior margin of hind coxae.
Pronotum ochraceous. Inner area of pronotum with following black marks: pair of medial longitudinal fasciae broadened at posterior ends; pair of spots or longitudinal small fasciae between median parts of paramedian fissures and posterior ends of lateral fissures; pair of fasciae along lateral fissures, often not complete; pair of curved fasciae along lateral margins of inner area; other irregular marks. Pronotal collar with pair of spots at lateral corners; with posterior marginal area very narrow. Anterior margin of pronotum wider than head including compound eyes. Anterolateral pronotal collar with two or three indistinct teeth.
Mesonotum greenish ochraceous with following black to fuscous marks: medial longitudinal fascia suddenly broadened from about middle posteriorly to reach anterior margin of cruciform elevation, narrower than median breadth of obconical sublateral marks on lateral sigilla; pair of small roundish spots just enclosing scutal depressions; pair of large obconical paramedian marks falling on submedian sigilla; pair of long obconical, but partly fading, sublateral marks falling on lateral sigilla; pair of small spots on posterolateral corners. Cruciform elevation green to greenish ochraceous with fuscous anterior subapical parts and posterior margin. Thoracic sternites ochraceous.
Legs greenish ochraceous to ochraceous with black to fuscous marks. Fore-femur with minute subapical spine as well as primary and secondary spines, all black except their brown tips.
Wings hyaline. Forewing barely tinged; comparatively short and broad. Vein R+Sc mostly reddish ochraceous. Infuscation present at bases of apical cells 1, 2, 3, 5 and 7 and on CuA2. Minute spot appearing on each hind margin of RA2, RP, M1–4 and CuA1, forming a series of spots on subapical margin of forewing. Base of ulnar cell 1 with black node. Basal membrane reduced and gray. Hind wing short, its apex barely reaching the junction of m-cu and M4. Base of hind wing jugum gray.
Operculum greenish ochraceous; much wider than long, with widely rounded posterior apex barely reaching posterior margin of sternite II and with posterolateral corner slightly concave. Opercula widely separated from each other.
Abdomen about as long as or slightly longer than distance from head to cruciform elevation. Tergite 2 brown with greenish posterior margin and medial longitudinal fuscous fascia. Tergites 3–7 black each with blue caudal margin and brown medial patch. Tergites 3–7 with pair of sublateral greenish ochraceous patches, which are densely covered with silvery hairs. Posterior margin of tergite 3 slightly wider than anterior margin of mesonotum. Timbal cover brownish gray without marks; globose, about 1.2 times wider than long, with anterior inner margin roundly convex widely, not angled, and with posterior inner corner being widely separated from posterior margin of tergite 2. Timbal completely concealed by timbal cover in dorsal view. Abdominal sternites mostly fuscous with bluish posterior margin on each of sternites IV–VI.
Genitalia (Fig. 3 C, D): Pygofer barrel-shaped in ventral view. Uncus bifurcate. Uncal lobe curved outward, with spine on its lateral margin and with truncate and laterally acute apex directed downward in ventral view. Both uncal lobes forming heart shape with their inner margins, which is longer than wide. Dorsal beak triangular, shorter than anal styles. Basal lobe of pygofer absent.
Distribution. Philippines (E. Luzon).
