Male black dorsally with creamy white markings as follows: crown with median anterior spot and one lateral spot in front of and adjacent to eye, one spot on lateral most area, one posterior somewhat V-shaped area on mesonotum, spot at apices of each claval vein and clavus, one basal spot on forewing and median large somewhat wedge-shaped spot at midlength enclosing costal margin, extending almost to half width mesally. Face with frontoclypeus medially creamy white, rest pale brown. Dorsal areas of thoracic pleura yellowish white, sternites pale brown. Legs ochraceous with blackish claws. Female dirty white, crown with large X-shaped marking on disc, one spot on either posterior inner margin of eyes black. Face as in male. Pronotum with pale brownish longitudinal areas on either side of median line. Pleurites and sternites as in male, fore tibiae reddish. Forewing apical margin piceous continued towards base to some length on costa, veins defining apical cells brownish.

Head, pronotum and basal half of forewings punctate. Carinae on crown prominent and lateral carinae reflexed.

Male genitalia. Pygofer elongate, longer than height, distal 0.33 region separated by dorsal marginal incision, posterodorsal region inwardly curved, apically narrowed, its dorsal margin serrate. Subgenital plate foot-shaped, with scattered macrosetae. Style sinuate with convoluted apical region. Connective with stem more than 4 times as long as arms, with anterior median lobe. Aedeagus in lateral aspect stout, with well developed lateral lobes, shaft short with basal short finger like processes, shaft apex widened in lateral view, gonopore apical. Segment X cylindrical and elongate, without any processes.

Female genitalia. Seventh sternite slightly narrowed posteriorly, posterior margin with deep V-shaped median excavation and lateral margins rounded.

Measurements. Male 5.1 mm long, 1.0 mm wide across eyes and 1.2 mm wide across posterolateral angles of pronotum. Female 5.5 mm long, 1.1 mm wide across eyes and 1.3 mm wide across posterolateral angles of pronotum.

Material examined. INDIA: Manipur: Senapati, Sijang Mongjang , 2♂, 1♀, 1053 m, 28.ix.2013, Sweepnet, Yeshwanth, H.M. ( UASB).

Remarks. This species is sexually dimorphic as far as colour is concerned and the head, pronotum and basal region of forewings are punctate. This species is only tentatively placed in the genus Onukia. This Chines species is recorded for the first time from the subcontinent.
