Edulia glareosa nov.sp. ( Figs 1-3 )

H o l o t y p e: China, Yunnan, Dali Bai Aut. Pref., foothills of Diacang Shan, W Dali , 2170 m, 25°42'07''N, 100°03'00''E, 6.IX.2009 (cS) ; paratypes: same data, 17 exx. (cS), 17 exx. (cB) ; same data, 2960-2980 m, 25°41'50.9''N, 100°06'017-28.3''E, Wrase 6.IX.2009, 1 ex. (cS), 1 ex. (cB) ; same data, Mao Jiao Shan, W pass, 56 km NE Dali , 2362 m, 25°55'12''N, 100°39'18''E, 4.IX.2009, 1 ex. (cS) ; Lincang Prf., Xue Shan, 48 km N Lincang, 2070 m, 24°19'03''N, 100°07'13''E, 12.IX.2009, 1 ex. (cS) .

D e s c r i p t i o n: Length of body about 6 mm; from anterior margin of head to posterior margin of elytra: 3 mm. Similar to Edulia anthracina (SCHEERPELTZ 1977) from Nepal and W Bengala, but visibly larger and longer, with similar coloration but with darker and not reddened and with bluish reflections elytra, legs testaceous clear instead dark brown; antennae proportionally longer, with antennomeres less combined each other; head much elongated and narrower, sub rectangular, with sub rectilinear sides instead rounded; eyes a little larger; pronotum leaner, more elongated and narrow, not dilated before, with more pronounced anterior angles; elytra proportionally longer and wider, with scutellum evidently much larger, with more prominent and marked humeri and surface more opaque because of a more or less polygonal micro reticulation.

Tergite and sternite of male genital segment as in Figs 1-2 . Aedeagus ( Fig. 3 ) similar to that of Edulia anthracina , but a little bigger (0,74 mm long), with different parameres and inner sac.

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

E t y m o l o g y: From the Latin glareosus - a - um (gravelly), by the favourite habitat of the species.

N o t e: The species was collected in "stone and gravel pit, on loamy steep faces with moss; former stone pit, in gravel/under stones".

At the description of the genus, ( BORDONI 2002) originally called Lepta, name later changed to Edulia as nomen preoccupatum (BORDONI 2007), I wrote that at least one of the two then known species [purpurescens (CAMERON 1926)] seems to live on the banks of rivers in the gravel and debris.
