( Fig. 2 )

Type material. Holotype: male ( Fig. 2 ), E. Luzon, Aurora, 8 km W. of Baler, Sierra Madre, Mingan Mts., 471 m, 16°41.463’N 121°23.86’E, 18 VI 2007, J.H. Lourens ( IRSNB). Paratype: 1 male, E. Luzon, Aurora, Sierra Madre, 15 km W. of Dibulo, 650 m, 16°33.176’N 122°13.386’E, 26–27 IX 2008, J.H. Lourens ( IRSNB).

Etymology. The species is named for the Professor Chris Simon at the University of Connecticut, who supported the author’s works.

Measurements of types (in mm, 2 males). Length of body: 23.4 (23.3–23.5); length of forewing: 32.0 (32.0–32.0); width of forewing: 10.9 (10.8–10.9); width of head including eyes: 6.9 (6.9–6.9); width of pronotum: 9.0 (9.0–9.0); wing span: 70.8 (69.6–71.9).

Diagnosis. This species is closely allied to O. viridicincta but distinguished by the following characters: body larger (about 23.4 mm long versus 16.0–21.0 mm long in viridicincta ); pronotum with pair of medial longitudinal black fasciae (with just one, fused, medial longitudinal black fascia in viridicincta ); anterior margin of pronotum wider (narrower in viridicincta ) than head including compound eyes; forewing costal vein slightly enlarged near node (distinctly enlarged to form protuberance in viridicincta ); basal vein of apical cell 1 comparatively shorter, less than one-third (more than one-third in viridicincta ) as long as longitudinal vein of apical cell 1; timbal cover without any marks (margined with fuscous in viridicincta ).

Description of male ( Fig. 2 ). Head green 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. Supraantennal 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 green. 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 (indistinct in holotype); with posterior marginal area very narrow. Anterior margin of pronotum wider than head including compound eyes. Anterolateral pronotal collar barely dentate.

Mesonotum green to greenish ochraceous with following black to fuscous marks: medial longitudinal fascia suddenly broadened from about middle posteriorly to reach anterior margin of cruciform elevation, broader than median breadth of 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 greenish ochraceous.

Legs greenish ochraceous to ochraceous with black to fuscous marks. Fore-femur with one (paratype) or two (holotype) minute subapical spines as well as primary and secondary spines, all black except their brown tips.

Wings hyaline. Forewing tinged with pale brown. Vein R+Sc mostly reddish ochraceous but partly mixed with green. Infuscation present at bases of apical cells 1–7 and on CuA2. Spot appearing on each hind margin of RA2, RP, M1–4 and CuA1, forming a series of spots on subapical margin of forewing. Last spot (on CuA1) largest among marginal spots. Base of ulnar cell 1 with black node. Basal membrane and base of hind wing jugum slightly grayish jade green.

Operculum light green to greenish ochraceous; much wider than long, with narrowly rounded posterior apex barely reaching posterior margin of sternite II and with posterolateral corner truncate and 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 mostly brown without medial mark. Tergites 3–8 black each with green 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 light green to greenish ochraceous without marks; globose, about 1.2 times wider than long, with anterior inner corner roundly angled and with posterior inner corner being close to posterior margin of tergite 2. Timbal completely concealed by timbal cover in dorsal view. Abdominal sternites mostly fuscous.

Genitalia ( Fig. 2 C, D): Pygofer barrel-shaped in ventral view. Uncus bifurcate. Uncal lobe roundly curved outward, with spine on its lateral margin and with apex directed toward center in ventral view. Both uncal lobes forming heart shape with their inner margins, which is wider than long. Dorsal beak triangular, about as long as or slightly shorter than anal styles. Basal lobe of pygofer absent.

Distribution. Philippines (E. Luzon).

Remarks. This species is also similar to O. nigristigma (cf. Lee 2010), but the latter is distinguished from all its congeners by the forewing with the costal margin distinctly bent and convex after node, more slender male abdomen, timbal covers semi-quadrangular, very large and slightly longer than wide and timbal covers close together with very narrow space between them.

From the next two new species, O. simonae sp. nov. is distinguished by the following characters: mesonotum with medial longitudinal fascia being broad, broader than median breadth of sublateral marks on lateral sigilla; forewing distinctly tinged with pale brown; forewing with infuscation much more developed; forewing with basal membrane being broad and jade green; timbal cover with anterior inner corner roundly angled; timbal cover with posterior inner corner being close to posterior margin of tergite 2; both uncal lobes forming heart shape with their inner margins, which is wider than long; uncal lobes with apex directed toward center in ventral view.
