Atopolinus hanmi nov.sp.

M a t e r i a l s t u d i e d: Holotype: Xizuang A. R. (Tibet), Hanmi, Motuo coun., 2200 m, L. Tang 19.VIII.2005 ( SNUC).

D e s c r i p t i o n: Length of body about 9 mm; from anterior margin of head to posterior margin of elytra: 4,8 mm. Apterous. Body without micro-sculpture, apart the abdomen with transverse micro-striature. Yellowish brown light (but immature). Head large, ovoidal, largely dilated posteriad and narrow anteriorly, with rounded sides from the eyes to the neck. Eyes very small but a little protruding. Surface of head with polygonal micro-reticulation and sparse, fine puncturation; 4 punctures between the eyes to form a quadrilater. Pronotum narrow, longer and narrower than head, with very evident oblique anterior margins, obsolete anterior angles, and sinuate sides. Surface with dorsal series of 6 fine and spaced punctures and lateral series of 3 punctures. Elytra short, dilated posteriad, with obsolete humeral angles. Surface with fine, very spaced puncturation, arranged in 4 spaced series. Abdomen with fine and dense, transverse micro-striation and fine, very spaced puncturation.

Posterior margin of the 6° visible abdominal tergite with two lateral, long lobules ( Fig. 105 ); posterior margin of the 6° visible abdominal sternite with a wide, median emargination. Tergite and sternite of the male genital segment as in Figs 106-107 . Aedeagus ( Fig. 108 ) large, 2,4 mm long, sub-spherical, with asymmetrical pseudoparameres; inner sac with thin spinulae.

E t y m o l o g y: The specific epithet refers to the type locality, as a noun in apposition.

G e o g r a p h i c a l d i s t r i b u t i o n: The species is known only from the type locality, in Tibet.

N o t e: Other species have the 6° visible abdominal tergite with lateral lobules at the posterior margin, as A. puetzi BORDONI 2009b and A. uncinatus BORDONI 2010 from Yunnan. From these taxa the new species differs by external and sexual characters.

The Atopolinus COIFFAIT 1982 described in these pages (apart A. subruber nov.sp.) are very similar to each other. Almost all are shiny, without micro-sculpture, reddish brown, more or less light, with very sparse puncturation on head, whereby the study of the aedeagus and other sexual characters is fundamental.

The species of Atopolinus known from China before this contribution, apart the taxa cited in these pages, are the following: A. sichuanicus BORDONI 2003 (Sichuan) , A. fellowesi BORDONI 2003a (Guanxi) , A. dabaesis BORDONI 2003b (Shaanxi-Sichuan), A. montanellus BORDONI 2004 (Sichuan) , A. brunneus BORDONI 2009 (Sichuan) , A.

gaoligong BORDONI 2007 (Yunnan), A. watanabei BORDONI 2009a (Yunnan) , A. rubescens BORDONI 2009a (Yunnan) , A. brachypterus BORDONI 2009b (Yunnan) , A. abnormis BORDONI 2009b (Yunnan) , A. puetzi BORDONI 2009b (Yunnan) , A. uncinatus BORDONI 2010 (Yunnan) , A. repostus BORDONI 2012 (Yunnan) , A. eminens BORDONI 2012 (Yunnan) .
