Mahavana acinosa nov.sp. (Figs 11-15)

E x a m i n e d m a t e r i a l: Holotype 3: Yunnan, Lincang env., 2100 m, A. Tilli VIII.2008 (cB).

D e s c r i p t i o n Body length 5 mm; length from anterior margin of head to posterior margin of elytra 2,2 mm. Similar to M. schuelkei but smaller. Head (Fig. 11) shorter and narrower, with sub-rectilinear and sub-parallel sides. Eyes composed by more ommatidia, not so concave. Surface almost completly without micro-sculpture, with smaller and sparser puncturation, with median strip and posterior half nearly devoid of punctures. Last three antennomeres as in Fig. 12. Pronotum evidently longer and a little wider than head. Surface with sparse puncturation. Elytra with almost obsolete humeral angles. Abdomen with sparser puncturation.

Tergite and sternite of the male genital segment as in Figs 13-14. Aedeagus (Fig. 15), 1,1 mm long, more or less ovoidal, with parameres of particular shape; inner sac with 7-8 large scales in the distal portion, in the form of grape.

E t y m o l o g y: The specific epithet refers to the Latin acinus- i (acinus), in relation to the shape of the scales of the inner sac of the aedeagus.

G e o g r a f i c a l d i s t r i b u t i o n This species is known only from the type locality.
