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 and Liu et al. 2019: fig. 7 A), the tongue-shaped labium (vs diamond-shaped; cf. Fig. 23 C and Liu et al. 2019: figs 6 F, 8 D) and the tent-shaped marking of female epigaster (vs triangular; cf. Fig. 23 H and Liu et al. 2016: fig. 5 F). Description. Male (holotype). Body: habitus as in Fig. 22 A – C; body length 1.28. Carapace (Fig. 22 E, G): 0.57 long, 0.45 wide. Eyes as in Fig. 22 D, E. Clypeus as in Fig. 22 D. Sternum as in Fig. 22 F. Mouthparts (Figs 22 D, F, 24 C): 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): 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). Female (SYNU -1553). Same as male except as noted. Body: habitus as in Fig. 23 A – C; body length 1.31. Carapace (Fig. 23 E, G): 0.64 long, 0.47 wide. Abdomen: 0.68 long. Epigaster (Fig. 23 H): without special external features, with a tent-shaped marking visible through cuticle. Endogyne (Fig. 24 F, G): with long medial clavate sclerite (AUS), provided with pair of long lateral protrusions (Pr); lateral protrusions at angle of about 30 ° with medial clavate sclerite; anterior receptaculum (ARe) rounded, semitransparent, slightly longer than AUS; posterior plate (PP) present, large. Distribution. Known only from the type locality. Etymology. The specific name is derived from the Latin tent and refers to the tent-shaped marking on epigaster of female.
