( Figs 6 , 7 ) Length: male, 4.0 mm; female, 4.2-4.3 mm . Dorsum pale brown to brown; crown with whitish yellow stripe medially, on each side from ocelli to near apex and adjacent each eye; ocelli and eyes dark brown in male or ocelli reddish and eyes yellowish in female ( Figs 6a, 6e ). Face whitish yellow except for dark anterior area ( Figs 6c, 6d ). Pronotum and mesonotum with pale fine medial stripe ( Figs 6a, 6e ). Forewing brownish hyaline, with subapical costal area pale with a red costa oblique stripe ( Fig. 6g ). Crown distinctly angularly produced, median length longer than interocular width, slightly narrower than pronotum; coronal suture distinct, 1/2 median length. Face with transclypeal suture indistinct ( Figs 6c, 6d ). Forewing similar in width throughout length with apex rounded ( Fig. 6g ). Male pygofer with posterior margin concave medially; with small setae on posteroventral area; with a long, dorsally curved ventral process, apex hook-shaped ( Fig. 7a ). Subgenital plates slender, with row of lateral macrosetae and several short fine setae and apically with long fine setae ( Fig. 7b ). Connective T-shaped with stem and arms short. Style slender, sickle shaped with apex pointed; with several microsetae ( Fig. 7c ). Aedeagus with short preatrium and dorsal apodeme; shaft laterally compressed with basal dorsal triangular projection on each side and one ventral bifurcate process near midlength, crescent-shape in ventral view, gonopore apical ( Figs 7d, 7e ). Female. Valvulae as in Figs 6 i- 6l. Etymology. The specific epithet refers to the type locality. Material examined. Holotype : ♂ , China , Guizhou Province , Libo County ( 513 m ), 30 October 2018 , coll. Yan Jiang. Paratypes : 2♀♀ , data same as holotype . Remarks. This species is similar to Ujna liangae Yang et al ., 2014 in having the forewing with a red costal oblique stripe and similar genitalia, but its aedeagus is broader in lateral view with processes dorsal rather than ventral in U . liangae .
