Diagnosis. The new species is similar to Orchestina flava Ono, 2005 in the yellow carapace and the strongly coiled sperm duct, but can be distinguished by the strongly enlarged palpal tibia (vs not enlarged; cf. Fig. 15 A, B and Ono 2005: figs 8–10), the rectangular labium (vs rounded; cf. Fig. 15 C and Ono 2005: fig. 3) and the obscure marking of endogyne (vs nearly triangular marking; cf. Fig. 14 H and Ono 2005: fig. 6). Description. Male (holotype). Body: habitus as in Fig. 13 A – C; body length 1.05. Carapace (Fig. 13 E, G): 0.54 long, 0.42 wide; yellow. Eyes (Fig. 13 D, E): well developed, PME largest. Clypeus as in Fig. 13 D. Sternum as in Fig. 13 F. Mouthparts (Figs 13 D, F, 15 C): labium rectangular, with anterior margin anteriorly projecting at middle, not fused to sternum; endites strongly sclerotized, with serrula in single row, outer margin smoothly curved. Abdomen ovoid, 0.48 long; dorsum soft portions pale white, without color pattern. Legs: yellow, without color pattern; femur IV thickened, wider than femora I-III. Palp (Fig. 15 A, B, D): tibia strongly enlarged, length / width = 1.87, cymbium small; bulb long pear-shaped in lateral view, with ventral side strongly protruding proximally, ca 1.09 × as wide as tibia; the sperm duct with two loops in prolateral view; embolus long tube-shaped, with a sub-apical node.
