Type material.

Holotype: JAPAN · ♀; Okinawa-ken, Iheyajima Island, Mt. Aha-dake; 27.02N, 127.93E; alt. 10 m; 26 December 2012; D. Li, F.X. Liu and X. Xu leg.; XUX-2012-502.

Paratypes: JAPAN · 6 ♀♀; same data as for holotype; XUX-2012-504 to 519.

Diagnosis.

Females of H. aha sp. nov. cannot be distinguished morphologically from those of H. gayozan sp. nov. but can be distinguished from those of H. kubayama sp. nov. by the receptacular clusters without genital stalks; and from those of H. mae sp. nov. by the inner receptacular clusters similar to or larger than laterals ( Fig. 15 A–F View Figure 15 ). Heptathela aha sp. nov. can also be diagnosed from all other Okinawa group Heptathela species by the following unique nucleotide substitutions in the standard DNA barcode alignment: C (41), C (179), G (182), G (233), T (248), G (251), T (326), A (347), G (359), C (473), C (492), A (536), T (651).

Description.

Female (Holotype). Carapace brown; opisthosoma brown, brown tergites with black plaques; cheliceral groove with 12 pronounced denticles; seven spinnerets. Measurements: BL 12.60, CL 5.55, CW 5.00, OL 6.82, OW 5.50; ALE> PLE> PME> AME; palp 9.90 (3.40 + 1.71 + 2.18 + 2.61), leg I 11.34 (3.31 + 2.05 + 2.31 + 2.35 + 1.32), leg II 11.65 (3.51 + 1.98 + 2.03 + 2.53 + 1.60), leg III 11.92 (3.30 + 1.90 + 2.05 + 2.97 + 1.70), leg IV 16.96 (4.88 + 2.22 + 2.98 + 34.45 + 2.43).

Female genitalia. A pair of depressions on the ventro-lateral part of the genital atrium ( Fig. 15 D–F View Figure 15 ). A pair of receptacular clusters along the anterior margin of bursa copulatrix, divided into two parts, both without genital stalks ( Fig. 15 A–F View Figure 15 ).

Male. Unknown.
