Thorax black, narrow lateral margin and very broad posterior margin of pronotum brown; mesoscutellum (not including mesoscutellar appendage), a short stripe on posterior margin of mesoscutal lateral lobe, anterior and posterior margins of parapsis, metascutellum, cenchri, postspiracular sclerite, prepectus (not epicnemium) and dorsal margin of metapleuron yellow brown. Abdomen black, narrow posterior margin of tergite 1 (Fig. 6 a), about apical half of tergites 2–10 and apical 0.25 of each sternite dark reddish brown to yellow brown, cerci and ovipositor sheath pale brown.

Hairs on dorsum of head and mesopleuron dense, hardly curved at apex, about 0.9–1 times diameter of median ocellus (Figs 3 a–b); hairs on mesoscutal middle and lateral lobes about 0.8 times as long as diameter of median ocellus; dorsum of abdominal tergites 1, 4–8 distinctly pubescent, hairs on tergite 1 not longer and denser than other tergites, tergites 2–3 largely, mesoscutellar appendage and intertergites of abdomen entirely glabrous (Fig. 6 a).
Labrum subtriangular, apical corner distinctly angled but not very acute; clypeus flat, without middle ridge, anterior margin almost truncate, very shallowly and broadly incised; malar space as long as diameter of median ocellus; distance between eyes at level of anterior tentorial pits 1.2 times as long as longest axis of eye (Fig. 3 b); left mandible as Fig. 11 j; hind orbit with a distinct occipital carina in lower half; middle fovea roundish, deep, not open to frons; lateral fovea minute, with an indistinct tubercle; frons subquadrate, frontal ridge indistinct; POL: OOL: OCL=15: 30: 24; interocellar furrow short, broad and deep, postocellar furrow narrow and indistinct, clearly bent forward at middle; postocellar area flat, clearly below temple, 1.7 times as broad as long, posterior margin not elevated; lateral furrows very shallow and indistinct in anterior 0.7, replaced by a low carina in posterior 0.3, straight, distinctly divergent backwards; head roundly dilated behind eyes in dorsal view (Fig. 4 a). Antenna as long as thorax, antennomere 3 about 1.1 times as long as antennomeres 4 and 5 together and 0.9 times as long as antennomeres 6–9 together, antennomere 7 about 1.2 times as long as broad (Fig. 11 a). Mesoscutal middle lobe with narrow but distinct middle furrow; mesoscutellum weakly and roundly elevated, anterior margin subtriangularly protruding, transverse anterior furrow shallow; mesoscutellar appendage short with middle length about 1.1 times as long as diameter of median ocellus; mesoscutellum 6 times as long as mesoscutellar appendage; cenchrus transverse, slightly broader than long, CD=1.5 (Fig. 6 a); mesepisternum roundly and weakly elevated at middle, without distinct ridge. Venation as Fig. 1 a, cell 2Rs about 0.8 times as long as cells 1R1+1Rs, cell A of forewing weakly constricted at basal 0.25, where distance between 1A and 2A+3A about 5 times as broad as vein 2A+3A; vein 1M as long as vein 1m-cu, vein 2r1 meeting cell 2Rs at apical 0.35.

Male. Body length 14 mm; color, punctation and structure similar to female except for following: head black, labrum and narrow posterior margin of temple brown; each femur largely dark brown; malar space 0.8 times as long as diameter of median ocellus; distance between eyes at level of anterior tentorial pits about 1.1 times as long as longest axis of eye; subgenital 1.1 times as long as broad, apical margin obtusely truncate; harpes about 2 times as long as broad; penis valve not dissected but similar to Fig. 10a in outline, dorsal apical hook long and strongly tapering toward apex.
Distribution. India (Sikkim) (Fig. 12).
Material examined. Type. Holotype: ♀, “Sikkim”; “Coll. Konow”; “ Colochelyna montana Knw., Sikkim.”; “ Holotypus ”[red]; “ Typus ”[red]; “GBIF-GISHym 4192”. (SDEI).
Other specimens. 1♀, MUSEUM PARIS, DARJILING, (MONTAGNES), HARMAND 1888; 3363, 86; Neocolochelyna montana Konow, Malaise det., 1935; Coll. Malaise; montana. (SNHM). 1Ƌ, “SIKKIM, Runjit Valley, 4-94, BINGHAM COLL ”; “ COLL. C. T. Bingham, 96-30”; “British Museum”; “ Colochelyna montana Knw, Malaise det.” (BMNH).
Host plant. Unknown.
Remarks. N. montana is similar to N. acutilabria sp. nov.. See the above key for the differences between the two species.
The holotype has a large hole on right side of mesonotum. Besides, the left prepectus (not epicnemium) in front of the postspiracular sclerite is much larger than the lateral ocellus. It should be abnormal because the prepectus on the right side is unrecognizable, and in N. acutilabria the prepectus is also very small and linear.
