Segestria nipponica Kishida, 1913

Figs 6 A–C, 12B.

Segestria nipponica Kishida, 1913: 42 , figs 1–4 (♂).

Segestria komatsuana Komatsu, 1939: 101 , pl. 5 (♀; name attributed to Kishida but never described by that author); Yaginuma, 1971: 27, pl. 5, f. 21 (♀).

Segestria nipponica Yaginuma, 1986: 25 , f. 16.6 (♂ ♀; synonymized with S. komatsuana ); Chikuni, 1989: 25, f. 3 (♂); Ono, 2009: 99, f. 6–8 (♂).

Material examined: 1♂ [photo of the palp], JAPAN, Ibaraki Pref., Hokyo-zan, Oda, Mt. Tsukuba-shi , 23.09.2018 (Yuya Suzuki) .

Diagnosis. This species is most similar to S. fengi sp. n. Both species have very similar bulbs: elongate, with bulbous basal part and bent tip of embolus. Male of S. nipponica differs from those of S. fengi sp. n. by thinner bulb (length/width ratio 2.63 vs. 2.17) and relatively larger palp segments (cf. Figs 6 A–C and 6D–F).

Description. See Ono (2009).

Comments. The species is not properly known. We had an opportunity to study only figures of male palp. A single record of S. senoculata (Linnaeus, 1758) from Japan (Boesenberg & Strand 1906) seems to refer to S. nipponica .
