Type locality. China, Hubei province, Dabie Shan Mts., 31°07'06''N, 115°48'57''E, 640 m.

Type material. 41 specimens — Holotype: male (SYSU): “ CHINA: Hubei province / Dabie Shan [Mts.], 640 m / 31°07’06’’N, 115°48’57’’E / V. Grebennikov leg. 11.–21.iv.2008 [printed]”. Paratypes: 8♂♂ 6♀♀ and 26 unsexed specimens, same label data as holotype (BMNH, CNCO, EUMJ, USNM, NHMW, NMPC, ZSMC).

Additional material examined. 1♀, CHINA: Anhui, Huang Shan, 60 km NNW Tunxi, nr. Tang Kou, 900– 1000 m, 31.x.1997, H. Schönmann leg. (CWBS 292) (NHMW).

Diagnosis. Small, broad and moderately convex species; body length 1.6–1.7 mm, width 1.0– 1.1 mm. Sides of pronotum slightly rounded, distinctly and broadly bordered; pronotum with longitudinal impressions between sides and disc. Lateral margin of elytra visible throughout elytral length except for apex. All above specimens are macropterous.

Male genitalia. Median lobe of aedeagus rather thin, almost parallel-sided subbasally, slightly bent ventrad at midlength, and indistinctly attenuating in apical part; apex with minute hook. Median lobe with minute pores subapically. Parameres short and stout, with four setae on apex and two located subapically, base with long field of pores along ventral surface (Fig. 1).

Bionomics. Collected in hygropetric habitats, in a thin film of water flowing on rock covered with a macroscopic algal mat (Figs 3–4).

Distribution. So far known from two localities in Hubei and Anhui provinces, China. The distance between localities is ca. 250 km (Fig. 7). The record from Anhui province needs to be confirmed by a male. Etymology. The new species is dedicated to Professor Fu Xinhua (College of Plant Science and Department, Huazhong Agricultural University, Wuhan, P.R. China), for facilitating the V. Grebennikov’s fieldwork during which this new species was collected.
