Diagnosis.

The new species is similar to Orchestina manicata Simon, 1893 in the enlarged palpal tibiae and the pear-shaped bulb, but can be distinguished by the shape of embolus, which is boot-shaped in lateral view and straight in dorsal view (vs triangular bifid; cf. Fig. 27 A, B, D and Ranasinghe and Benjamin 2025: figs 3 D, 4 A), the smoothly curved outer margin of male endites (vs straight; cf. Fig. 27 C and Ranasinghe and Benjamin 2025: fig. 3 D) and the long medial clavate sclerite of endogyne (vs short; cf. Fig. 27 F and Ranasinghe and Benjamin 2025: fig. 4 B).
