Type material.

Holotype: JAPAN · ♀; Okinawa-ken, Naha, Shuri, Sueyoshi Park; 26.23N, 127.72E; alt. 45 m; 17 December 2012; D. Li, F.X. Liu and X. Xu leg.; XUX-2012-309.

Paratype: JAPAN · 1 ♀; same data as for holotype; XUX-2012-308.

Diagnosis.

Females of H. shuri sp. nov. can be distinguished from those of H. tokashiki sp. nov. by paired receptacular clusters with larger granules ( Fig. 20 A–D ). Heptathela shuri 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: G (89), G (131), C (134), C (396), C (510), C (512), A (524), T (641).

Description.

Female (Holotype). Carapace yellow brown; opisthosoma brown, tergites with brown plaques; cheliceral groove with 12 pronounced denticles; seven spinnerets. Measurements: BL 10.78, CL 5.30, CW 4.12, OL 6.25, OW 4.40; ALE> PLE> PME> AME; palp 8.93 (3.15 + 1.43 + 2.03 + 2.32), leg I 10.91 (3.48 + 1.87 + 2.05 + 2.21 + 1.30), leg II 10.64 (3.18 + 1.85 + 1.86 + 2.28 + 1.47), leg III 11.26 (3.03 + 1.81 + 1.77 + 2.90 + 1.75), leg IV 17.02 (4.62 + 2.28 + 3.07 + 4.50 + 2.55).

Male. Unknown.
