Type material.

Holotype: ♂ (NSMT-Ar 8515) from JAPAN: Honshu, Okayama Prefecture, Tsuyama-shi, Kamo-cho, Uno, alt. ca. 100 m, 12.VI.2009, K. Nojima leg. Paratypes: 1♀ (NSMT-Ar 8516) from JAPAN: Honshu, Okayama Prefecture, Okayama-shi, Kita-ku, Awai, alt. 100-200 m, 6.VI.2009, K. Nojima leg.; 2♀ (NSMT-Ar 8568) from JAPAN: Honshu, Aichi Prefecture, Toyota-shi, Sakaue-cho, Mt. Rokusho-san, alt. ca. 400 m, 18.X.2009, K. Ogata leg. Not examined.

Diagnosis.

Trogloneta nojimai can be distinguished from other congeners but except of T. yuensis by the globular abdomen in both sexes (Figure 1A, B), the palp with a long embolus and a distinctly extended cymbial conductor (Figure 1E), and a long and narrow scape in the epigyne (Figure 1G, H). It seems more similar to T. yuensis in share with the structure of palp and the configuration of epigyne, but differs from the latter by the abdomen without a dorsal-posteriorly pointed tubercle in both sexes (Figure 1A, B vs. Figure 6A, B, E, F), a straight embolic end and lack of cymbial process (Figure 1E, F vs. Figure 7 A–D), and by the oval spermathecae (Figure 1G vs. Figure 8C, D).

Taxonomic justification.

Although the type material of this species has not been examined for this study, the shape of palpal bulb, the configuration of epigyne, the patterns of eyes arrangement, and the distinctly elevated, conical carapace in male leave little doubt that it should be a member of the genus Trogloneta , but not Mysmena . The original illustrations of palp and epigyne of T. nojimai by ( Ono 2010: figs 1-8) are rather simple and show many important similarities in comparison with those of T. yuensis (Figs 7 A–D, 8 A–D), as one of Trogloneta species. Therefore, we propose it as a new combination, Trogloneta nojimai (Ono, 2010), comb. n., transferring it from Mysmena .
