Diagnosis.

Male is similar to that of Yaginumaella flexa Song & Chai, 1992 (cf. Fig. 8 C-F and Peng 2020: 492, fig. 363 a-c) in having the long posterior lobe reaching 1 / 2 length of tibia and curved sperm duct arising from 9 o’clock, but can be easily distinguished from it by the horn-like retrolateral tibial apophysis (vs nearly C-shaped in Y. flexa ) and the relatively long embolus with an uneven and thin spine-like tip (vs spine-like, tapering in Y. flexa ). The female of this species resembles that of Y. longnanensis Yang, Tang & Kim, 1997 (cf. Fig. 9 C, D and Peng 2020: 494, fig. 365 d, e) in having the short but broad copulatory ducts and the nearly round spermathecae, but can be easily distinguished from it by the sloping extending copulatory ducts (vs parallel in Y. longnanensis ) and the spermathecae separated from each other (vs touching in Y. longnanensis ).

Epigyne (Fig. 9 C, D ). Copulatory openings located at postero-lateral part of atrium, covered by the nearly C-shaped margin, accompanied with the triangular hoods. Copulatory ducts short, slanted posteriorly in dorsal view. Spermathecae round, barely touching each other. Fertilization ducts slightly longer than copulatory ducts, medially located at anterior spermathecae.

Distribution.

Known only from the type locality in Taiwan and Jiangxi Province, China (Fig. 13 ).

Remarks.

According to Peng et al. (2002) the original material consisted of two male specimens; the paratype was recorded from Jiangxi province, but the details of the type locality were omitted and not provided in their paper. The male and female specimens of this species are, unsurprisingly, recollected from Jinggang Mountain National Nature Reserve in the same province.
