Type material
Holotype: male, CHINA: Tibet, Tingri, 28º48’ N, 86º48’ E, 4300 m, 3 Jul. 2004, collected by Yibin Ba and Aimin Shi ( MHBU). Paratypes: 60 males and 55 females, same data as the holotype ( MHBU).
Diagnosis
The new species can be distinguished from other species of Ascelosodis by surface of head with dense Vshaped rugae. It is closely related to A. concinnus Bates, 1879 (as demonstrated by clypeal lobe sharply divided from lateral lobes by deep incisions, lateral margins of pronotum distinctly uprising, elytral base not bordered), but can be distinguished by sides of prothorax not ciliate beneath, lateral margins of pronotum rounded, humeral angles of elytra nearly rectangular, elytral surface with dense smooth tubercles, epipleura with very sparse granules.
Etymology
Named after dorsal surface of head with dense rugae.
Description
Male ( Figs. 27–34 View FIGURES 27 – 39 ). Ovate, black to brown, shiny; antennae, legs and palpi pitchybrown to reddishbrown. Clypeal lobe ( Fig. 28 View FIGURES 27 – 39 ) clearly prominent, nearly trapezoid, anterior margin straight, sharply divided from lateral lobes by deep acuteangled incisions. Outer margins of genae gradually converging to clypeus. Dorsal surface of head weakly convex, disc with dense Vshaped rugae ( Fig. 142 View FIGURES 141 – 145. 141 – 142 ); punctures on clypeal lobe and genae coarse, sometimes elongated and connected. Antennae ( Fig. 27 View FIGURES 27 – 39 ) short, apices extending as far as middle of pronotum. Length (width) ratio of antennomeres 2 to 11 as follows: 5.2(4.0): 5.0(3.8): 3.9(3.8): 3.9(3.8): 3.5(3.8): 3.5(4.0): 4.0(4.0): 4.5(5.1): 4.9(6.1): 5.1(4.9). Apical part of inner margin of antennomere 9, apical part of inner and outer margins of antennomere 10 and apical part of antennomere 11 with dense hair and sparse long setae.
Pronotum ( Fig. 29 View FIGURES 27 – 39 ) transverse, 1.90–2.05 (2.01, on the average, n=10) times as wide as long, widest immediately before the middle, 1.60–1.71 (1.65, on the average, n=10) times as wide as head. Lateral margins of pronotum rounded, with short setae, and obscurely bordered along entire length; anterior margin sinuate, base almost parallel with it, both bordered laterally or along entire length. Anterior angles of pronotum nearly rectangular; posterior ones obtuse. Pronotal surface with dense coarse punctures finer at disc than laterally, and with the lateral margins distinctly uprising. Propleura deeply concave, with incomplete punctures. Intercoxal process of prosternum linguiform, weakly prominent behind coxae and steeply sloping at apex.
Elytra shortly ovate, 1.15–1.21 (1.18, on the average, n=10) times as long as wide, widest before the middle, 1.13–1.21 (1.17, on the average, n=10) times as wide as pronotum. Elytral base not bordered, humeral angles nearly rectangular. Surface of elytra convex and rugged, with dense smooth tubercles finer at disc than laterally, each tubercle with a seta, sides sparsely ciliate beneath. Epipleura narrow, completely ventral, outer margins not extending to shoulders, and with very sparse granules. Visible abdominal ventrites with punctures, each puncture with a seta. 1 to 3 visible abdominal ventrites with rugae.
Legs short, femora invisible from above. Outer apical angles of protibiae strongly elongated, extending beyond anterior margin of protarsomere 4. Length ratio of metatarsomeres 1–4 as follows: 15: 5: 5: 12.
Aedeagus ( Figs. 30–32 View FIGURES 27 – 39 ): length 1.33 mm (when body length 5.6 mm). Parameres 0.71 mm long and 0.21 mm wide, apices without setae. Spiculum gastrale as in Fig. 33 View FIGURES 27 – 39 . Apical margin of abdominal sternite VIII deeply sinuate ( Fig. 34 View FIGURES 27 – 39 ).
Female ( Figs 35–39 View FIGURES 27 – 39 ): Difficult to distinguish from male by general characters. Ovipositor as in Figs. 35–36 View FIGURES 27 – 39 . Posterior margins of urotergite VIII ( Fig. 37 View FIGURES 27 – 39 ) and spiculum ventrale ( Fig. 39 View FIGURES 27 – 39 ) nearly arcuate. Urosternite VIII ( Fig. 38 View FIGURES 27 – 39 ) with posterior margin weakly sinuate.
