Ghauriana sinensis Qin & Zhang , sp. n.

( Figs 65–80 )

Type materials. Holotype, male ( NWAFU), Huaping, Guangxi Autonomous Region, 29 Aug. 2000, coll. Zhenjiang Liu. Paratypes, 1 male, same data as holotype; 2 males, Lingchuan County, Guangxi Autonomous Region, coll. Xiaolin Lu, by light trap; 1 male, Baoshan County, Yunnan Province, 24 Jun. 1974, 1700 m, coll. Yao Zhou & Feng Yuan; 6 males, Sanchahe, Mengyang, Yunnan Province, 7 Jun. 1991, 800 m, coll. Rungang Tian, Wanzhi Cai & Yinglun Wang, by light trap ( NWAFU).

Description. Length, male 3.6–3.8 mm.

Ground color yellow. Vertex yellow to yellowish brown, coronal suture brownish. Eyes brown, circles aound ocelli ivory or brownish. Face, forewing, abdomen and legs yellow. Pronotum mostly yellow to brownish, with irregular patches along arc of anterior margin. Centre of scutellum anteriorly and caudad of scutoscutellar sulcus with yellow patch, respectively, at each side of lateral margins with a relatively small patch, scutoscutellar sulcus brown ( Fig. 65 ). Forewing semi-transparent, hindwing transparent, without fine spines on margins ( Fig. 69 ).

Body robust. Head equally wide as pronotum ( Fig. 65 ). Vertex rounded anteriorly, in midlength slightly shorter than width between eyes ( Fig. 65 ), in profile regularly curving into convex and slightly elongated face ( Figs 66, 67 ), coronal suture clear, reaching half of vertex length ( Fig. 65 ). Pronotum nearly twice as long as vertex in midline ( Fig. 65 ). Forewing narrow, rounded apically, apical cells occupying less than third its length, veins RP and MP’ separated at bases, both arise from r cell and MP”+CuA’ from m cell, c and r cells almost equally wide ( Fig. 68 ). Hindwing with bifurcation of CuA drawn apicad ( Fig. 69 ).

Basal sternal abdominal apodemes parallel sided, nearly reaching middle of segment V ( Fig. 80 ). Male pygofer slightly elongate, triangular, terminal part strongly narrowing caudad, with a few rigid microsetae at apex of lobe, ventral appendage narrow, slightly sinuate, longer than pygofer side in profile, apical third bearing hair-like cuticular outgrowths on dorsal side ( Figs 70, 72 ), dorsal bridge slightly less than half length of lobe in dorsal aspect ( Fig. 71 ). Subgenital plate far exceeding pygofer side, broad at base and gradually tapering towards apex, ventral margin curved dorsad in apical half, setae of basal group undifferentiated, dorsal margin with ca. 24 short microsetae, ca. 16 spine-like lateral macrosetae in one row and numerous feeble microsetae in 2–3 rows starting along with macrosetae ( Figs 70, 78 ). Apex of paramere thickened, dentifer bearing 8 teeth, 2–3 setae below and few sensory pits more cephalad ( Fig. 79 ). Aedeagus shaft tubular, short and robust, approximately half length of preatrium, gonopore ventrad near apex ( Figs 70, 75, 76 ). Connective lamellate, apical margin notched medially ( Figs 73, 77 ). Anal tube process broad, reaching half height of pygofer, apex rounded and adorned with tiny neoplasitc processes ( Figs 70, 74 ).

Remarks. The genus Ghauriana was established by Thapa in 1985 and was previously known only from the type species from Nepal. The new species here described differs from G. pecularia in having the vertex midlength slightly shorter than the width between the eyes (in G. p e c u l a r i a the vertex is distinctly shorter than the width between the eyes ca. 0.50: 1) and the ventral pygofer appendage bearing hair-like cuticular outgrowths on the dorsal side in the apical third (absent in G. p e c u l a r i a).

Etymology. The species name alludes to the locality of the type material ( China).

Distribution. China (Guangxi, Yunnan).
