( Figs 4a–4d ) Description: Length of each forewing 3.5–3.6 mm (n = 1). Specimens in alcohol with compound eyes black, legs and thorax dark brown, abdomen brown dorsally, pale yellow ventrally, wings light brown. Male genitalia: In lateral view, sternum IX nearly oblong, with each anterodorsal angles produced into projections ( Fig. 4c ). Tergum IX, segment X and horizontal part of inner branch of phallic sheath process fused into a complex, originating about halfway along upper margin of sternum IX, ( Fig. 4c ), vertical part of inner branch of phallic sheath process paired, each with three spines apically ( Figs 4b, 4c ); lateral branch of phallic sheath process paired and sparsely setose, each arched in lateral view and elongate tongue-shaped in dorsal view ( Figs 4b, 4c ). Superior appendages slightly S-shaped, issuing from protrusion of sternum IX in lateral view ( Fig. 4c ), extending dorsocaudad beyond apex of phallus ( Fig. 4b ). Phallus tapering from base to apex, in lateral view its basal half forming angle at about 90° with distal half ( Fig. 4c ). In dorsal view, phallic guide with apex expanded into a disc ( Fig. 4d ), in lateral view with apex bifurcate, dorsal branch straight upwards and acute, ventral branch triangular ( Fig. 4c ). Coxopodites ventrally fused mesally with posterior margin somewhat W-shaped in ventral view ( Fig. 4a ); in lateral view subrectangular, each with dorsal process triangular, smooth and hairless, and ventral process rounded, setose, shorter than dorsal process ( Fig. 4c ). Harpagones inserted between dorsal and ventral processes of coxopodite, tongue-shaped, setose and longer than dorsal processes of coxopodites in lateral view ( Fig. 4c ). Diagnosis: This species is similar to Tinodes eris Malicky & Sangpradub 2001 (in Malicky et al . 2001 ) from Thailand . However, the new species can be easily distinguished from it by the inner phallic sheath process with its base fused with the complex of tergum IX and X and the other portion free from the complex, vertical, and bifurcate. Holotype : Male, P. R . China , Si-chuan Province : Ya-an city, Zhou-gong river , 29.5900°N , 102.5900°E , atl. 600–800 m , 8 June 1996 , light trap , leg. L. Yang & X. Wang ( NJAU ). Distribution: China (Si-chuan). Etymology: The new species is named after Prof. Lianfang Yang in honor of her great contributions to the Trichoptera fauna of China .
