Diagnosis. This new species is separated from the congeners by the following points. The male palpal embolus arises from the prolateral part of the bulb and the sclerotized swell- ings are situated anteriorly on the epigyne, while in the other congeners, an embolus arises from the ventromedian part of the bulb and an epigyne anteriorly has recurved ridges or no remarkable structure.

Description. Measurements based on male holotype and female paratype. Body length ♂ 4.74, ♀ 6.32. Carapace length ♂ 2.14, ♀ 2.36; width ♂ 1.68, ♀ 1.80. Abdomen length ♂ 2.60, ♀ 3.96; width ♂ 1.40, ♀ 2.12. Eye sizes: AME ♂ 0.08, ♀ 0.08; ALE ♂ 0.11, ♀ 0.13; PME ♂ 0.07, ♀ 0.08; PLE ♂ 0.09, ♀ 0.11. Distances between eyes: AME-AME ♂ 0.04, ♀ 0.05; AME-ALE ♂ 0.01, ♀ 0.01; PME-PME ♂ 0.05, ♀ 0.06; PME- PLE ♂ 0.04, ♀ 0.04; ALE-PLE ♂ 0.04, ♀ 0.05. MOA anterior width ♂ 0.19, ♀ 0.21; posterior width ♂ 0.19, ♀ 0.22; length ♂ 0.22, ♀ 0.24. Clypeus height ♂ 0.11, ♀ 0.11. Lengths of legs as in Table 2.

Variation. 1♀ other than paratype. Body length 5.40; car- apace length 2.32, width 1.84; abdomen length 3.08, width 1.88.

Ventral spines on legs I and II. ♂ and ♀: tibiae: I and II 0-0-0; metatarsi: I and II 2-2-0.

Color. Male and female: cephalothorax and appendages dark reddish brown, but mouth parts, sternum and coxae of legs paler; abdomen with dorsal and lateral surfaces dark grayish brown, ventral surface yellowish brown.

Male palp ( Fig. 5 View Fig A–C): terminal apophysis pointed apically; embolus arising from prolateral part of bulb; median apophysis relatively large with small flat projection protrud- ing retrolaterally; cymbium with short ridge situated proximally; retrolateral tibial apophysis somewhat short, with apical part bluntly pointed in ventral view. Epigyne ( Fig. 5 D View Fig ) with a pair of sclerotized swellings situated anteriorly, medi- an plate relatively narrow. Female internal genitalia ( Fig. 5 E View Fig ) with copulatory ducts long, complexly winding and occupying posterior half of vulva.

Distribution. Amami-Ōshima Is., Kagoshima Pref., Southwest Japan.

Etymology. Specific name is dedicated to the collector of the type specimens.
