Yunna fungicola n. sp.

Material examined:

Holotype ♂: Yunnan, Baoshan Pref., Gaoligong Shan, E pass 36 km SE Tengchong, 2200 m, 24.49N, 98.46E, M. Schülke 31.V.2007 (cS); paratypes: same data, 1 ♀ (cS), 1 ♂, 2 ♀ ♀ (cB).

Description:

Body 6 mm long; length from the antrerior margin of the head to the posterior margin of elytra: 3,5 mm. Forebody black, abdomen brown, antennae brown black, legs testaceous. Head sub rectangular, with sub parallel sides and posterior angles strictly rounded. Eyes moderately large and protruding. Surface of the head shiny, with two series of three points between the eyes and with punctation more or less large and scattered. Pronotum longer and narrower than head, with slightly oblique anterior margins and largely rounded anterior angles. Surface shiny, with dorsal series of 9-10 irregular points and lateral series of 5-6 irregular points. Elytra large, longer and larger than pronotum, sub rectangular, with sub parallel sides and evident humera. Surface irregular but shiny, with some series of very fine points. Abdomen with fine and more or less polygonal microreticulation and fine punctation.

Male genital segment as in fig. 12 , with sternite sub quadrate ( fig. 13 ) and partially membranous. Aedeagus ( fig. 14 ) very small (0, 85 mm long), diaphanous, with symmetrival and peculiar parameres, internal sac moderately long and narrow, transparent, with scattered minute scales.

Etymology:

It take its name from the Latin fungicolus - a- um (fungiculous).

Bionomy:

“Deciduous forest, in litter, wood and fungi” (from the label).

Distribution:

I know this species only from the type locality.

Notes:

The genus Yunna BORDONI, 2002 seems to live only in China and was represented until now by two species ( Y. micophora BORDONI, 2002 from Yunnan and the cited Y. rubens )). The new species is similar to these but larger and with different aedeagus.
