description: Nebria (Barbonebriola) kagmara sp. nov. (Fig. 14)
Holotype ♂: Nepal, Prov. Karnali, Distr. Dolpo, Kagmara La, westside, High Camp, 4300 m, 29. 6. 2009, leg. Santos Tamang (NME).
Paratypes: 35 ♂ 33 ♀, same data as holotype (NME, NMBE, cSCHM); 22 ♂ 9 ♀, Nepal, Prov. Karnali, Distr. Dolpo, Kagmara La, eastside, High Camp, 4400 m, 1. 7. 2009, leg. Santos Tamang; (NME); 91 ♂ 61 ♀, Nepal, Prov. Karnali, Distr. Dolpo, Kagmara Lekh, below Kagmara La, 4400 m, 1. 7. 2009, leg. Santos Tamang; (NME, NMBE, cSCHM).
Body length 9–11 mm. Colour dark brown. Head black, pronotum often lighter than the head. Mandibulae and appendages of head piceous. Antennae brown. Femora dark brown, trochanters, tibiae, knees and tarsi lightened brown.
Head with a shallow transverse impression behind the prominent eyes. Labrum long, with anterior margin faintly convex, bearing six setae; anterior margin in the area of the four median setae bulging. Apical margin of clypeus concave. Shallow supraorbital impression longitudinally wrinkled. One supraorbital seta. Frons distinctly transversally wrinkled. Vertex faintly punctate near the transverse impression. Antennae extending to one-third of the elytra. Antennal scape elongate, subcylindrical-ovoid, basally narrowed, as long as the eye's diameter, with one dorsal seta. 2 nd antennomere with one ventroapical seta. Maxillary stipes laterally with a berry-like bulge with 9–10 tubercles bearing each a robust seta. Penultimate labial palpomere trisetose. Ligula spiny, with two lateral setae. Mentum with bifid medial tooth. Submentum with a row of 20–26 setae. Microreticulation of the head isodiametric.
Pronotum subcordate, transverse, ratio width/length of the pronotum 1.39–1.48. Lateral margin convex, narrowed basally, widely rounded to the anterior angles, evenly and convexly narrowed to the posterior angle; somewhat more strongly narrowed just in front of the posterior angles (Fig. 15E). Largest width at apical fourth. Posterior angles distinctly narrower than the anterior ones. Lateral channel narrow and moderately deep. Lateral margin only just in front of the posterior angle moderately blade-like, obliquely or vertically upturned. Posterior angles acute and moderately protruding. Anterior angles moderately protruding. Basal margin straight without incision towards the basal fovea. Pronotal disc moderately convex. Basal fovea shallow, anterior and posterior transverse sulci shallow, median line shallow. Basal fovea, anterior and posterior transverse sulci sparsely and faintly punctate, lateral groove impunctate. Apical margination of the pronotum restricted to lateral one-third, merges with the apex of the anterior angle. Base of the pronotum not margined. One midlateral seta (rarely asymmetrically bisetose), which is inserted in the lateral channel, at apical fourth of the pronotum. Basolateral seta absent. Microreticulation of the pronotum isodiametric, impunctate on disc. Proepisternum smooth. Prosternal process elongate, flattened or with a longitudinal bulge, margined laterally and unmargined at apex.
Elytral silhouette convex, ovoid-elongate, lateral margin rectilinear, widest behind the middle; subapically faintly sinuate. Elytral apex acuminate, but rounded. Basal margination straight, smoothly merged with the lateral margination. Humeral carina faintly developed. Striae deep, distinct on disc, weakly punctate. Punctation of the striae distinct only on disc, obliterated basally and apically. Striae obliterate towards the apex and towards the lateral margin, striae 7 and 8 visible as a row of pores. Intervals convex, more convex on disc and towards the basal margin. Apical carina evanescent. Intervals 3, 5 and 7 asetose. Scutellar seta absent. Microreticulation oblong. Mesepisterna smooth. Metepisterna 1.7 times as long as wide, smooth or coarsely punctate. Metacoxa generally with two (1–4) basal and one apical setae. Hindwings present as a strap-like vestige of one fifth to one sixth of the elytral length.
Sternum 2 laterally smooth, faintly punctate. Sternum 3 with a row of 2–8 medial setae. Sterna 4–6 each with 3–7 posterior paramedial setae. Anal sternum with 2–3 paramedial setae in the male and 2–4 in the female. All sterna with faint impressions laterally.
Legs long and slender. Tarsi dorsally glabrous. Protarsus of the male with tarsomeres 1–3 distinctly broadened, ventrally with pads of adhesive setae. Ventroapical tooth of the metatarsomere 4 small. Meso- and metatarsomeres 2–4 ventroapically with long setae. All tarsomeres 5 ventrally with two rows of 3–5 short setae. Metatarsomere 5 as long as the metatarsomeres 3+4.
Male genitalia: Edeagus (Fig. 8B): Basal part of the median lobe wide, with short basolateral membranous lobes. Mid-shaft thick, regulary curved, progressively narrowed to apex. Tip of the apex short, acute, triangular in dorsal view. Apex faintly deflected to the left. Mid-shaft of the everted endophallus densely and extensively covered with long setae.
Female genitalia: Gonocoxa (Fig. 9E): Gonocoxite 2 slender and long, longer than half the length of gonocoxite 1, distinctly narrowing naer base, parallel sided in median part, narrowing towards apex which is faintly deflected. Apex rounded, distinctly arcuate dorsally, but dorsally not grooved. Ventral preapical insertion furrow elongate-oval, with two nematiforme setae. Gonocoxites ventrally unjointed and continuously sclerotized, dorsally separated by a membranous area.
Body ratios: hea.w/fro.w = 1.39±0.026 (1.35–1.43); prm.w/hea.w = 1.30± 0.024 (1.27–1.36); prm.w/prp.w = 1.72±0.049 (1.65–1.82); pra.w/prp.w = 1.24± 0.39 (1.18–1.30); ely.w/prm.w = 1.58± 0.035 (1.51–1.62); prm.w/prm.l = 1.43± 0.028 (1.39–1.48; ely.l/ely.w = 1.57± 0.029 (1.54–1.63).
Etymology: The specific epithet (noun in apposition) refers to the type locality Kagmara La.
Diagnosis: N. kagmara is separable from all Barbonebriola species by the base of the pronotum which is not incised at the basal grooves, and by the weakly punctate striae of the elytra.
Distribution (Fig. 16, Nr. 10): Known only from the type locality on the southern slope of Kanjiroba Himal, the pass Kagmara La in the Dolpo district (Karnali zone, West Nepal).
N. kagmara sp. nov. is the easternmost species of the subgenus Barbonebriola subgen. nov. Obviously the watershed between the Karnali and Kali Gandaki river catchments represents the eastern border of the Barbonebriola distribution. The species immediately east of the Kali Gandaki river on the west slopes of the Annapurna South Himal is a species belonging to the subgenus Epinebriola (N. triseritata sp. nov., see below).
Habitat (Fig. 17): Alpine plateau with vegetation mats, rivulets and stone debris.
