Paratypes: 11 ♂ 7 ♀, same data as holotype ( NMBE, cSCHM); 3 ♂ 1 ♀, Nepal, Manaslu Himal, Rumche Tal to Rupina La pass , 4200 mNN, 24. 6. 2001, leg. S. Tamang ( cSCHM); 52 ♂ 35 ♀, Manaslu Himal , Dudh Pokhari , 4300– 4400 mNN, 30. 6. 2001, leg. S. Tamang, H.S. Galel & S. Gurung. ( NMBE, cSCHM); 2 ♀, Nepal, Gorkha Dist., zw. Tabruk und Rupina La , 4100–4400 m, 9. Aug. 1983, leg. Martens & Schawaller ( SMNS), Nepal-Expedition Jochen Martens; labeled Nebria masrina Andr. det. Shilenkov [misidentification; specimens compared with the masrina holotype ( BMNH)].
Body length 11–12 mm. Colour black, appendages of head brown. Antennae brown, 1 st and 2 nd antennomeres darkened. Legs black, knees and tarsi brown.
Head with two shallow oblique impressions between the eyes. Labrum with anterior margin straight or slightly convex, bearing six setae. Apical margin of clypeus straight. Vertex impunctate, transversally wrinkled. Eyes weakly prominent. Generally one supraorbital seta (93% symmetrically unisetose, 7% asymmetrically bisetose). Antennae long and slender extending to one third of the elytra. Antennal scape elongate, a little longer than the eye's diameter, basally narrowed, subcylindrical apically, with one dorsal seta. 2 nd antennomere with one seta ventroapically. 4 th antennomere occasionally with additional fine seta near apex. Maxillary stipes with 6–7 setae. Ligula long, spiny, with two lateral setae. Penultimate labial palpomere trisetose. Mentum with bifid medial tooth. Submentum with a row of 10–14 setae. Microreticulation of the head isodiametric.
Pronotum faintly transverse, ratio width/length of the pronotum = 1.33. Lateral margin distinctly convex, narrowed basally, widely rounded to the anterior angles, in a straight line or even convexly narrowed to the posterior angles ( Fig. 31C View Fig ). Lateral explanation narrow with a conspicuous groove also apically, broadened basally. Lateral margin basally blade-like, obliquely or vertically upturned. Posterior angles distinct but not acute. Anterior angles very widely rounded, only weakly protruding. Basal margin weakly bisinuate, without a deep incision towards the basal fovea. Pronotal disc weakly convex. Basal fovea deep, anterior and posterior transverse impressions distinct, median longitudinal impression very weak. Basal fovea, anterior and posterior transverse impressions sparsely and faintly punctate; the narrow lateral groove impunctate. Apical margination of the pronotum restricted to lateral one-thirds, merges with a ridge at the anterior angle; the ridge distinctly continues along the lateral groove to the lateral seta ( Fig. 6B). Base of the pronotum not margined. Basolateral seta absent. 1(–2) midlateral setae in the apical third of the pronotum (87.3% bilateral unisetose, 12.7% asymmetrically bisetose); midlateral seta inserted in a distinct groove at the inside of the slightly upturned margin. Microreticulation of the pronotum isodiametric, impunctate on disc. Proepisternum smooth. Prosternal process faintly margined or almost unmargined.
Elytral silhouette broad, convex, ovoid, widest in or slightly behind the middle; subapically faintly sinuate. Elytral apex acutely rounded. Apical carina absent. Basal margination straight, smoothly merged with the lateral margination. Humeral carina faintly developed. Striae distinct on disc, faintly punctate. Striae obliterate towards the apex; striae 7 and 8 scarcely visible. Intervals rather convex, more convex on disc and towards the basal margin. Apical seta of the interval 3 mostly present, but hardly visible. Interval 3 with 3–5 setae adjoining stria 3. Scutellar seta variably present (61.4% symmetrically unisetose, 22.9% asymmetrically bisetose (1/2), 8.4% symmetrically bisetose, 7.2% asymmetrically asetose (0/1 or 0/2). Microreticulation oblong. Mesepisterna smooth. Metepisterna 1.6 times as long as wide, smooth. Metacoxa with (2–)3 basal and one apical setae. Hindwings present as a strap-like vestige of one fourth of the elytral length.
Sternum 3 medially asetose or oligosetose (0–2). Sterna 4–6 each with 4–8 posterior paramedial setae. Anal sternum with 2–3 paramedial setae in males and females.
Legs long and slender. All tarsi dorsally glabrous. Metatarsomere 4 ventroapically markedly projected. Meso- and metatarsomeres 2–4 ventroapically with long setae. All tarsomeres 5 ventrally with two rows of 4–5 short setae. Metatarsomere 5 distinctly longer than the metatarsomeres 3+4.
Male genitalia: Edeagus ( Fig. 20C View Fig ): Basal part of the median lobe wide, with prominent triangular basolateral lobes. Mid-shaft thin, slender, strongly curved at base, moderately curved and progressively narrowed to the apex. One third from the tip on the ventral side faintly bent. Apex deflected to the left. Mid-shaft of the endophallus densely packed with short setae.
Female genitalia: Gonocoxa ( Fig. 10C View Fig ): Gonocoxite 2 elongate-triangular, broad at base, longer than half the length of gonocoxite 1. Apex broadly rounded, dorsally arcuate, dorsally grooved. Ventral preapical insertion furrow short-oval, with two nematiforme setae. Gonocoxites ventrally unjointed and continuously sclerotized, dorsally separated by a membranous area.
Body ratios: hea.w/fro.w = 1.43±0.022 (1.39–1.47); prm.w/hea.w = 1.33± 0.053 (1.24–1.40); prm.w/prp.w = 1.61±0.039 (1.55–1.67); pra.w/prp.w = 1.12± 0.032 (1.05–1.16); ely.w/prm.w = 1.64±0.054 (1.56–1.71); prm.w/prm.l = 1.33± 0.028 (1.29–1.38); ely.l/ely.w = 1.57±0.031 (1.51–1.61).
Etymology: The specific epithet refers to the Sanskrit name of the Manaslu Mountain (manasa = spirit = anima (latin); "Mountain of Spirit").
Diagnosis: Close to N. impunctata sp. nov. from the Ganesh Himal. N. montisanimae sp. nov. differs from the N. impunctata sp. nov. by the more elongate elytra and by the faintly punctate striae (punctation absent in N. impunctate sp. nov.). N. montisanimae sp. nov. differs from the sympatric N. rupina sp. nov. by the absence of the basolateral setae of the pronotum, by the larger body size and by the more rounded elytral outline (slender in N. rupina sp. nov.).
Distribution ( Fig. 41 View Fig ): Known only from the type locality, the pass Rupina La on eastern slope of Himal Chuli (eastern part of the Manaslu Himal mountain range), western Central Nepal Himalaya.
Habitat: Not noted.
