Atopolinus eminens nov.sp. ( Figs 13-18 )

H o l o t y p e: China, Yunnan, Lincang Pref., Laobie Shan, Wei Bo Shan pass, 2370 m, 24°08'16''N, 99°42'53''E, 8.IX.2009 ; paratypes: same data, 4 (cS), 2, 2 (cB) ; Baoshan Pref., Gaoligong Shan , 78 km N Tengchong, 2000 m, 25°44'49''N, 98°33'29''E, 1.IX.2009, 1 (cB) .

D e s c r i p t i o n: Length of body 6,6 mm; from anterior margin of head to posterior margin of elytra: 3,8 mm. Similar to Atopolinus rubescens BORDONI for coloration, characterized by yellowish posterior margin of elytra and for the general body shape, but much smaller; head of similar shape, with eyes of equal size; pronotum narrower than in A. rubescens , with similar punctuation; third article of the antennae shorter than in A. rubescens ; elytra a little more narrow than in A. rubescens , sub rectangular, just dilated posteriad, with coarse punctuation, placed in a smaller number of series.

Sixt visible male tergite as in Figs 13-14 ; 6 ° visible sternite as in Fig. 15 ; male genital segment ( Fig. 16 ) narrow and equipped with a long posterior spine on the right pleura; sternite of the same as in Fig. 17 . Aedeagus ( Fig. 18 ), 1,7 mm long, with asymmetrical, large and partially membranous pseudoparameres; inner sac with three big and very long spines and with some smaller spines at the distal pore.

D i s t r i b u t i o n: This species is known only for the type localities.

E t y m o l o g y: From the Latin eminens - tis (remarkable).

N o t e: The specimens was collected in "creek valley, devast. second. decid. forest, litter and moss; cleft with creek and forest remnant, litter/soil". For the shape of the male genital segment this species is similar to Atopolinus asymetricus (COIFFAIT 1973) from Nepal and A. schuelkei BORDONI 2010 from Gaoligong Shan.
