Figs 3 K–N , 5 M , 10 E , 12 I –L , 37 A–E .

Dorsally uniformly chocolate brown, short median stripe on apex of crown, small spot in front of ocelli, pale yellow. Costal margin in basal 0.8 length hyaline interrupted twice in distal 0.33 by chocolate brown, more distal hyaline area extended mesally, obliquely across width of wing to inner apical cell, one spot on inner margin beyond clavus hyaline. Face, thoracic and abdominal pleurites and sternites and legs pale yellow, claws pale brown. Dorsum of abdomen and entire genital capsule chocolate brown, setae pale yellow.

Head, pronotum and mesonotum subequal in length. Crown with median carina prominent in basal half, lateral discal area obliquely and longitudinally rugose, crown conically produced in front of eyes and bluntly conically rounded.

Male genitalia. Pygofer height more than length in lateral view, dorsal margin slightly excavated near middle, posterodorsal lobe triangular with rounded angle, ventral margin constricted basally then rounded and obliquely upturned, without basal fracture on dorsal margin. Style and connective as in Figs 37C, D . Aedeagus with well developed preatrium and plate-like dorsal apodeme, dorsolateral lobe well developed oval, shaft of uniform width, with basal pair of slender lateral processes slightly shorter than shaft, gonopore subapical on ventral margin.

Female genitalia. Seventh sternite with posterior margin almost straight.

Measurements. Male 5.5 mm long, 1.1 mm wide across eyes and 1.27 mm wide across posterolateral angles of pronotum. Female 5.8 mm long, 1.27 mm wide across eyes and 1.4 mm wide across posterolateral angles of pronotum.

Material examined. INDIA: Holotype ♂, West Bengal: Darjeeling , 2176 m, 23.x.1981, C.A. Viraktamath ( UASB) . Paratypes; 1 ♂, 1 ♀, same data as Holotype ; 2 ♂, Arunachal Pradesh: 10 Km S Hunli , 1597 m, 28o 1905” N, 95o 56’ 152” E, 12, ix.2014, Yeshwanth, H.M. ; 1 ♂ same data except collected by Prathapan, K.D. ( UASB) .

Remarks. This species is very similar to O. connexa externally in coloration and the structure. However, the two species differ in the male genitalia characters as mentioned in the key.
