Diagnosis.

The new species is similar to Orchestina bialata Liu, Xiao & Xu, 2016 in the enlarged palpal tibiae and the shape of male endites, but can be distinguished by the sperm duct with five loops (vs four loops; cf. Fig. 24 A View Figure 24 and Liu et al. 2019: fig. 7 A), the tongue-shaped labium (vs diamond-shaped; cf. Fig. 23 C View Figure 23 and Liu et al. 2019: figs 6 F, 8 D) and the tent-shaped marking of female epigaster (vs triangular; cf. Fig. 23 H View Figure 23 and Liu et al. 2016: fig. 5 F).

Mouthparts (Figs 22 D, F View Figure 22 , 24 C View Figure 24 ): labium tongue-shaped, not fused to sternum, anterior margin not indented at middle; endites strongly sclerotized, with serrula in single row, outer margin strongly curved. Abdomen ovoid, 0.59 long; dorsum soft portions pale white, without color pattern. Legs: yellow, without color pattern; femur IV thickened, wider than femora I-III. Palp (Fig. 24 A, B, D, E View Figure 24 ): tibia strongly enlarged, length / width = 2.01, cymbium elongated ovoid; bulb pear-shaped in lateral view, with ventral side strongly protruding proximally, ca 1.36 × as wide as tibia; the sperm duct with five loops in prolateral view; embolus short, with sub-apical, opaque crest (Fig. 24 A, B View Figure 24 ).
