Bagmati) Pokhare NE Barahbise 2800 m 2.V.81 LÖbl &amp; Smetana (MHNG). <b>Paratypes:</b> 1 &amp;male;, 2 &amp;female;, NEPAL, Bagmati Zone, Yardang Ridge NE Barahbise, 3250 m, 5.IV.1981, I. LÖbl &amp; A. Smetana (MHNG); 1 &amp;male;, Bagmati Zone, Kalingchok NE Barahbise, Amatal Khola, Tingsang La, 3100 m, 27.X..1981, P. Cassagnau (MHNG); 1 &amp;female;, Bagmati Zone, Kalingchok NE Barahbise, Yardang Ridge, 3250 m, 28.X.1981, P. Cassagnou (MHNG). <b>Etymology.</b> The species epithet is the numbertwo in Sanskrit. <b>Description.</b> Length 1.60-1.82 mm. Head about 1.7 times as long as wide. Lower margin of frontoclypeus rounded, with long, prominent setae.Anterior marginof frontal rostrum rounded. Frontal sulcus between antennal tubercles narrow, widened posteriad, with carinate inner margins, extended to level of eye mid-length. Frontal carinae oblique, reticulate. Antennal tubercles prominent. Vertex convex, with mesal impression very shallow, narrowed posteriad, mesal carina near neck absent. Eyes prominent, with diameter about as half of interval to neck, consisting of seven facets. Genae reticulate. Temples weakly rounded, contours in dorsal view nearly oblique. Frontal carinae bearing rowsof short appressed setae. Temples and vertex with short appressed setae. Maxillary palpomere IV long about as head, with peduncle somewhat shorter than thickened apical part. Length/width ratio of antennomeres as: I 22/10: II 12/8: III 9/6: IV 7/6: V 7/6: VI 8/6: VII 8/6: VIII 8/6: IX 10/7: X 12/8: XI 24/13. Gular mound longer than wide, narrowed posteriad. Pronotum similar to that in <i>N. ekam</i>. Elytra nearly 1.4 times as long as pronotum, with lateral margins weakly rounded, at apices about 3.5 times as wide asat bases, not microsculptured, with three basal foveae, median longitudinal carina with margins well delimited, reaching nearly elytral mid-length, bearing double rows of setae, adsutural carina with single row of setae; disc with additional, outer double row of setae, intervals between rows of setae glabrous. Hind wings atrophied. Abdomen with tergite I slightly wider than elytra, broad paratergites, rounded lateral margins. <b>Male characters.</b> Metaventrite as in <i>N. ekam</i>. Aedeagus (Figs 28, 29) 0.35-0.37 mm long, with basal bulb not widened apically, its apicodorsal band narrowly notched in middle, dorsal capsule oval. <b>Measurements of the holotype (in mm).</b> Total length 1.82; length/width of head 0.41/0.24, pronotum 0.33/0.30, elytra 0.45/0.70 (0.20), tergite I 0.51/0.75; length of maxillary palpomere IV 0.40, length of aedeagus 0.37. <b>Diagnosis.</b> Length 1.60-1.82 mm. Anterior margin of frontal rostrum rounded. Frontal sulcus rather wide, distinctly widened posteriad. Maxillary palpomere IV long about as head, with peduncle shorter than thickened apical part. Elytron with discal carina short, extended to mid-length of disc, interval between carinae and laterally discal carina glabrous. Aedeagus with basal bulb not widened apically, oval apicodorsal capsule, and minute notch in middle of apicodorsal band. <b>Distribution.</b> Central Nepal. <b>Comments.</b> See key below to distinguish this species from its congeners.
