HOLOTYPE : J, ‘ Qingrenquan Dong ( 180 m ), Xingping Cun , Huanghua Xiang , Yichang Shi , [ Hubei , CHINA ], 24.vi.2010 , Hiroshi Miyama’ (NSMT) . PARATYPES : 2 ♀♀ , same label data as holotype (NSMT) ; 1 J, ‘Shikumen Dong, Songping Cun, Yezhou Zh. , Jianshi Xian, [ Hubei , CHINA ], 26.vi.2010 , Hiroshi Miyama’ (NSMT) . Diagnosis. Male : vertex simple, lacking modification; antennomeres VIII–XI modified; each eye composed of about 50 facets; pronotum with distinct lateral spines; metaventrite raised above metacoxae to form ridges, with dense setae along ridges; aedeagus with apical portion of the median lobe split to two parts, the dorsal part much shorter than the ventral part. Female : each eye composed of about 15 facets; may be identified by the association with male. Description. Male . Body ( Fig. 1A ) reddish brown, mouth parts, antennae and tarsi paler; BL 2.97 mm . HL 0.59–0.60 mm , HW 0.62–0.63 mm ; median longitudinal carina extending from base to level of eyes; each eye composed of about 50 facets; antennomeres VIII–IX modified ( Fig. 1B ). Pronotum slightly wider than long, PL 0.60–0.63 mm , PW 0.66–0.68 mm ; with distinct discal and lateral spines. Elytra slightly wider than long, EL 0.90–0.91 mm , EW 0.94–0.95 mm ; discal striae extending to apical 4/5 elytral length. Metaventrite ( Fig. 1C ) strongly raised above metacoxae, with pair of rows of dense setae; metacoxae and metatrochanters simple. Abdomen narrower than elytra, AL 0.85–0.86 mm , AW 0.88– 0.84 mm . Aedeagus ( Figs 1D, E ) asymmetric, length 0.66 mm . Female . Similar to male in general; each eye with about 15 facets; antennae and metaventrite simple. Tergite VIII (Fig. 12A) and sternite VIII (Fig. 12B) transverse; width of genital complex excluding lateral arms (Fig. 12C) 0.12 mm . Measurements: BL 2.65 mm ; HL 0.57–0.58 mm , HW 0.56–0.57 mm , PL 0.57–0.58 mm , PW 0.63–0.64 mm , EL 0.77–0.80 mm , EW 0.87–0.88 mm , AL 0.71–0.72 mm , AW 0.79–0. 82 mm . Etymology. The new species is named after the province where the type locality lies; adjective. Distribution. Central China : Hubei ( Fig. 13A ).
