Diagnosis.

Males and females of H. crypta sp. nov. cannot be distinguished morphologically from H. unten sp. nov. ( Figs 22 A–K View Figure 22 , 23 A–L View Figure 23 ), but can be diagnosed from H. unten sp. nov. by the following unique nucleotide substitutions in the standard DNA barcode alignment: C (26), A (32), C (50), T (60), T (110), G (153), T (194), C (197), T (269), C (281), T (284), C (338), A (341), T (357), C (416), T (428), C (458), A (482), T (488), G (551), T (581), T (635), G (638), G (641), C (644), C (656), as well as from all other Okinawa group Heptathela species by the following unique nucleotide substitutions in the standard DNA barcode alignment: C (26), T (110), G (551), C (656).

Description.

Male (Holotype). Carapace and opisthosoma description see H. unten sp. nov.; cheliceral groove with nine denticles of variable size; seven spinnerets.

Palp. Prolateral side of paracymbium unpigmented and unsclerotised, numerous setae and spines at the tip of paracymbium ( Fig. 22 I–K View Figure 22 ). Contrategulum margin incurved nearly in the middle, and the contrategulum divided into proximally serrated and distally smooth ( Fig. 22E, F, I, J View Figure 22 ). Tegulum with wide dorsal extension of terminal apophysis ( Fig. 22G, H, J View Figure 22 ), blunt terminal and small marginal apophysis ( Fig. 22H, I View Figure 22 ). Conductor sclerotised and ovate, prolateral conductor with one or two shallow folds, and with a serrated margin ( Fig. 22F, G, K View Figure 22 ). Embolus sclerotised, with a wide opening, the distal margin slightly sclerotised, and with a saddle-shaped margin in the retrolateral view ( Fig. 22F, G, K View Figure 22 ).

Females (N = 10). Carapace and opisthosoma description see H. unten sp. nov.; chelicerae with promargin of cheliceral groove with 13-14 pronounced denticles of variable size; seven spinnerets. Measurements: BL 8.35-16.50, CL 4.07-5.10, CW 3.30-4.80, OL 4.70-6.80, OW 3.00-5.20; ALE> PLE> PME> AME; palp 7.70 (2.87 + 1.13 + 1.68 + 2.02), leg I 9.57 (3.07 + 1.70 + 1.70 + 1.98 + 1.12), leg II 9.64 (2.95 + 1.68 + 1.61 + 2.08 + 1.32), leg III 9.60 (2.68 + 1.69 + 1.50 + 2.30 + 1.43), leg IV 14.21 (4.00 + 1.92 + 2.55 + 3.83 + 1.91).

Female genitalia. A pair of depressions on the ventro-lateral part of genital atrium indistinct ( Fig. 23F, J–L View Figure 23 ). Paired receptacular clusters along the anterior margin of bursa copulatrix, divided into two parts, the inners similar or smaller than the laterals, paired receptacular clusters tuberculate, without genital stalks ( Fig. 23C, G–L View Figure 23 ).

Etymology.
