Type material.

Holotype: JAPAN · ♂; Kagoshima-ken, Amami, Uken-son, Oshima-gun, Road No. 85, Redsoil Park; 28.24N, 129.34E; alt. 260 m; 15 September 2013; D. Li and B. Wu leg.; XUX-2013-297.

Paratypes: JAPAN · 2 ♂♂, 2 ♀♀; same data as for holotype; XUX-2013-298, 301, 302, 304 · 3 ♂♂, 5 ♀♀; Kagoshima-ken, Amami, Yamato-son, Amami Forest Park; 28.31N, 129.33E; alt. 300 m; 17 September 2013; D. Li and B. Wu leg.; XUX-2013-305 to 314.

Diagnosis.

Males of H. uken sp. nov. can be distinguished from those of H. kanenoi by the spiniform conductor apex ( Fig. 13A, B, D, E View Figure 13 ), from those of H. amamiensis by the dorsal extension of tegular terminal apophysis without dentation ( Fig. 13F, G View Figure 13 ). Females of H. uken sp. nov. cannot be diagnosed from those of the other Amami group Heptathela species morphologically ( Fig. 13 H–M View Figure 13 ), only by the following unique nucleotide substitutions in the standard DNA barcode alignment: T (161), T (191), G (227), C (236), T (287), T (297), A (299), C (389), T (395), G (413), C (416), G (503), C (509), C (510), T (527), T (558), G (560), G (569), C (578), T (584), C (596), T (614), G (629), G (635), C (650), C (665).

Description.

Male (Holotype). Carapace brown; opisthosoma light brown, with dark brown tergites; cheliceral groove with eight denticles; seven spinnerets. Measurements: BL 11.60, CL 6.10, CW 5.60, OL 6.00, OW 4.30; ALE> PLE> PME> AME; leg I 17.47 (4.80 + 2.28 + 3.67+ 4.42 + 2.30), leg II 17.95 (4.65 + 2.30 + 3.60 + 4.90 + 2.50), leg III 18.80 (4.45 + 2.40 + 3.55 + 5.20 + 3.20), leg IV 23.60 (5.60 + 2.45 + 4.45 + 7.20 + 3.90).

Palp. Prolateral side of paracymbium unpigmented and unsclerotised, numerous setae and spines at the tip of paracymbium ( Fig. 13 A–C View Figure 13 ). Contrategulum with serrated margin ( Fig. 13A, B, D, F View Figure 13 ). Tegulum with smooth dorsal extension of terminal apophysis ( Fig. 13F, G View Figure 13 ). Conductor wide, sclerotised and rugose, with several folds and a spiniform apex ( Fig. 13A, B, D, F View Figure 13 ). Embolus sclerotised, wide with a flat opening, and wide saddle-shaped in the prolateral view ( Fig. 13A, B, D, E View Figure 13 ).

Females (N = 8). Carapace and opisthosoma colour as in male; cheliceral groove with 13-15 pronounced denticles; tergites similar to male; 7 or 8 spinnerets. Measurements: BL 11.80-16.00, CL 5.90-8.26, CW 5.20-7.20, OL 6.00-8.10, OW 4.60-6.00; ALE> PLE> PME> AME; palp 10.04 (3.05 + 1.89 + 2.30 + 2.80), leg I 12.05 (3.90 + 2.10 + 2.25 + 2.40 + 1.40), leg II 11.30 (3.55 + 2.05 + 1.80+ 2.45 + 1.45), leg III 12.42 (3.60 + 2.05 + 2.10 + 3.00 + 1.67), leg IV 18.33 (5.15 + 2.40 + 3.30 + 4.78 + 2.70).

Female genitalia. A pair of indistinct depressions on the ventro-lateral part of genital atrium ( Fig. 13K View Figure 13 ). Two pairs of receptacular clusters along the anterior margin of bursa copulatrix, the inners almost globose, with short genital stalks in distal view, the laterals tuberculate, without genital stalks ( Fig. 13 H–M View Figure 13 ).

Etymology.

The species epithet, a noun in apposition, refers to the type locality.

Distribution.
