Pseudognaptorina exsertogena

description: Pseudognaptorina exsertogena sp. n.   (Figs 1–12, 25–26, 29)   Description. Body black (teneral specimens reddish brown), weakly shining. Male body length 9.6– 1.7 mm, width 4.4–5.4 mm; female body length 10.4–12.5 mm, width 5.0– 6.1 mm.   
Male (Fig. 25). Anterior margin of clypeus straight. Outer margin of head with obtuse-angled incision above antennal base. Genae noticeably convex, parallel sided before eyes. Eyes protruding beyond outer margin of head. Dorsal surface of head weakly convex to flat, covered with moderately large punctures. Frontoclypeal suture fine. Antennae, when posteriorly extended, reaching pronotal base. Length (width) ratio of antennomeres 2 to 11 as follows: 8(8): 22(9): 11(9): 11(9): 10(8): 12(9): 10(12): 10(13): 10(13): 16(13).  
Pronotum (Fig. 1) transverse, 1.25–1.32 (1.28, on the average, n = 10) times as wide as long, widest behind the middle, 1.67–1.89 (1.76, on the average, n = 10) times as wide as head. Ratio of pronotal width at anterior margin to its maximum width and width at base (n = 10) 0.64: 1.00: 0.95, on the average. Outer margins of pronotum arcuately narrowing to anterior margin in anterior 1/3; in posterior 1/3 tapering to base with almost straight sides, bordered along entire length. Anterior and basal margins straight, not bordered. Anterior angles of pronotum obtuse, posterior ones almost rectsame, ventral view angular. Pronotal surface between outer margins convex, with fine median depression and moderately large punctures. Prothoracic hypomeron covered with shallow longitudinal wrinkles and granules. Prosternum in front of procoxae oblique to the horizontal plane; intercoxal process of prosternum steeply sloping behind procoxae.  
Elytra elongate-oval, 1.45–1.59 (1.53, on the average, n = 10) times as long as wide, widest before the middle, 1.34–1.47 (1.44, on the average, n = 10) times as wide as pronotum. Epipleural carina visible from above in anterior half and apical 1/5. Elytral surface between outer margin of epipleura and sutural margin weakly convex, sparsely covered with fine punctures and irregular wrinkles. Epipleural surface impunctate, covered with dense wrinkles. Abdominal ventrites covered with punctures and golden setae. Ventrites 1 to 3 covered with wrinkles.  
Legs (Figs 3–5) strong, length (width) ratio of pro-, meso-, and metafemora 70(20): 83(19): 100(20); that for corresponding tibiae 71(9): 69(9): 95(12). Upper edge of inner surface of profemur nearly straight. Mesotibiae slightly incurved. Hair brushes present on plantar surface of protarsomeres 1 to 3 and mesotarsomeres 1 and 2. Mesotarsomeres 3 with a bunch of pale hairs. Metatibiae weakly incurved, gradually widening toward apex, length (width) ratio of metatarsomeres 1 to 4 is as follows: 24(6.5): 12(6.3): 11(6.3): 23(6).  
Aedeagus (Figs 6–8): length 2.1 mm, width 0.43 mm (when body length 11.6 mm). Parameres strongly elongate, 0.72 mm long, 0.32 mm wide, with outer margins very slightly sinuate. Spiculum gastrale as in Fig. 9. Apical margin of abdominal sternite 8 sinuate (Fig. 10).  
Female (Fig. 26.). Body longer and wider. Antennae shorter than in male, not reaching pronotal base when posteriorly extended. Pronotum 1.30–1.39 (1.34, on the average, n = 10) times as wide as long, 1.74–1.87 (1.83, on the average, n = 10) times as wide as head. Ratio of pronotal width at anterior margin to its maximum width and width at base (n = 10) 0.56: 1.00: 0.91, on the average. Elytra more convex than in male, 1.37–1.43 (1.40, on the average, n = 10) times as long as wide, 1.33–1.43 (1.36, on the average, n = 10) times as wide as pronotum. Lower spur of protibiae small and pointed, upper spur blunt apically, noticeably larger than the lower one, but not particularly enlarged. Apical spurs on metatibiae of female narrow and parallel sided. Plantar surface of tarsal segments without hair brushes or tufts of light setae. Ovipositorial lobes (Figs 11–12) rounded apically, densely covered with setae.  
 Type material. Holotype male, CHINA: Tibet, Damxung county, Yangbajian, 3700–4100 m, N 30°06’ E 90°30’, 28 June 2004, Yi-Bin Ba and Ai-Min Shi leg. (MHBU). First label of the holotype (written with Chinese characters) see Fig. 29. Paratypes: 16 males (1, HNHM, 15, MHBU) and 24 females (1, HNHM, 15, MHBU), same data as holotype; 4 males and 1 female, CHINA: Tibet, Maizhokunggar county, 4100 m, N 29°48’ E 91°48’, 5 July 2002, Guo-Dong Ren leg. (MHBU).   
 Etymology. Named after the noticeably convex genae.   
 Diagnosis. This new species can be distinguished from Pseudognaptorina nepalica KASZAB, 1977 by the strongly elongate parameres (2.25 times as long as broad), with outer margins very slightly sinuate, epipleural carina visible from above in anterior half and apical 1/5, hair brushes present on plantar surface of mesotarsomeres 1 and 2.   
 Distribution. China: Tibet.
