Diagnosis.

Female body length 5.4-6.3 mm, forewing 5.0-5.8 mm (Fig. 46 ); male body length 4.3-4.9 mm, forewing 4.0-4.6 mm (Fig. 47 ). This species resembles L ( L. ) Leptochilus chinensis Gusenleitner, 2001 with similar coloration (Figs 27 , 28 , 46 , 47 ), antenna (Figs 36 , 53 ), occipital carina (Figs 32 , 51 ), pronotal carina (Figs 31 , 50 ), hind tarsi in male (Figs 28 , 47 ) and S2 (Figs 34 , 54 ). Male genitalia are different from L ( L. ) Leptochilus chinensis Gusenleitner, 2001 (Figs 37-39 , 55-57 ) by penis valve obvious narrow in the middle part, depression deeper than above at the top (Fig. 57 ). In addition, it can be distinguished from the related species and other members of the genus by the following character combination: in front view clypeus wider than long (1.1 × in female, 1.2 × in male), apically emargination wider than depth (2.6 × in female, 1.8 ×in male) (Figs 48 , 49 ), propodeum posterior surface with finely and oblique striae mixed with sparse punctures, propodeal concavity shallow, and propodeal carina present in lower part, and long about 2/3 as long as the propodeal concavity (Fig. 52 ).

Distribution.

China (Inner Mongolia, Gansu, Qinghai).
