Shi, A-M., Ren, G-D. & Merkl, O., 2007, Six New Species Of Gnaptorina Reitter, 1887 (Coleoptera, Tenebrionidae: Blaptini) From The Tibet Plateau, Acta Zoologica Academiae Scientiarum Hungaricae 53 (3), pp. 219-238 : 224-226

Gnaptorina kangmar sp. n.

( Figs 25–36 , 77–78, 87)

Description – Body black to brownish black, weakly shining. Male body length 8.9–10.5 mm, width 4.5–5.2 mm; female body length 10.2–10.8 mm, width 5.4–5.8 mm.

Male (Fig. 77). Anterior margin of clypeus slightly sinuate to straight. Outer margin of head with weak to very weak obtuse-angled incision above antennal base. Outer genal margin arcuately converging to clypeal base. Eyes not protruding beyond outer margin of head. Dorsal surface of head weakly convex, with moderately strong punctures. Antennae, when posteriorly extended, reaching posterior 1/4 of pronotum. Length (width) ratio of 2nd to 11th antennomeres 9 (9): 21(9): 11(9): 10(9): 11(9): 11(9): 11(13): 10(13): 12(14): 18(14).

Pronotum ( Fig. 25 ) transverse, 1.33–1.37 (1.35 on average, n = 9) times as wide as long, widest in the middle, 1.77–1.87 (1.82 on average, n = 9) times as wide as head. Ratio of pronotal width at anterior margin to its maximum width and width at base (n = 9) 0.58: 1.00: 0.92 on average. Outer margins of pronotum more sharply arcuately converging to anterior margin than to base, bordered along entire length. Anterior and basal margins straight, not bordered. Anterior angles of pronotum obtuse, rounded apically; posterior angles obtuse. Pronotal surface between outer margins regularly convex, punctures as strong as those on head; a very shallow and narrow elongate impression on each side of pronotal base. Prothoracic hypomeron weakly concave, covered with longitudinal wrinkles and very sparse granules. Intercoxal process of prosternum with shallow median depression, steeply sloping behind procoxae.

Elytra oval, 1.35–1.39 (1.37 on average, n = 9) times as long as wide, widest before the middle, 1.25–1.35 (1.29 on average, n = 9) times as wide as pronotum. Less than basal half of epipleural carina visible from above. Elytral surface between outer margin of epipleura and sutural margin convex, with fine punctures and irregular wrinkles. Epipleural surface smooth, densely covered with fine wrinkles. Visible abdominal ventrites with punctures and brown setae, 1st to 3rd ventrites with longitudinal wrinkles.

Legs ( Figs 27–29 ) strong, length (width) ratio of fore, middle and hind femora 77(23): 85(21): 100(23); that of corresponding tibiae: 64(9): 63(14): 92(17). Fore tibiae with serrate outer margin, shallow preapical incision, and massive upper spur at apical margin longer than 1st protarsomere, lower spur missing. Only 1st protarsomere with a tuft of light setae at apical margin of plantar surface. Hind tibiae weakly incurved, gradually widening toward apex. Length (width) ratio of 1st to 4th metatarsomeres 24(8.0): 11(7): 10(7): 23(6).

Aedeagus ( Figs 30–32 ): length 2.14 mm, width 0.46 mm. Parameres 0.54 mm long and 0.35 mm wide, with outer margins deely sinuate, and apical part weakly narrowing toward apex. Spiculum gastrale as in Fig. 33 . Apical margin of abdominal sternite 8 shallowly sinuate ( Fig. 34 ).

Female (Fig. 78). Body longer and wider. Antennae shorter and thicker. Epipleural carina visible from above in anterior 1/3 or less. Upper spur of fore tibiae long and wide, and rounded apically. Plantar surface of 1st protarsomeres without tuft of light setae. Ovipositor as in Figs 35–36 .

Type material – Holotype male, CHINA: Tibet, Kangmar , 4200 m, N 28°36’, E 89°42’, 2 July 2004, Yi-Bin Ba and Ai-Min Shi leg. ( MHBU). First label of the holotype (written with Chinese characters) see Fig. 87 . Paratypes: 8 males (1, HNHM, 7, MHBU) and 5 females (1, HNHM, 4, MHBU), same data as holotype .

Etymology – Named after the type locality.

Diagnosis – This new species resembles Gnaptorina compressa sp. n., with the following differences: anterior margin of clypeus slightly sinuate to straight; pronotum with outer margins arcuately narrowing to base in basal half, anterior same, ventral view margin not bordered, posterior angles obtuse, upper surface without smooth spot; middle part of prosternum in front of procoxae not concave; less than basal half of epipleural carina visible from above.

Distribution – China: Tibet.
