Diagnosis
Females of H. otoha sp. nov. can be distinguished from those of H. yanbaruensis, H. unten sp. nov., and H. crypta sp. nov. by the inner receptacular clusters with several granules, albeit these inner clusters are difficult to be separated from the laterals (Fig. 19A–D). H. otoha 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 (83), G (206), G (488).
Description
Female (Holotype). Carapace yellow brown; opisthosoma light brown, with brown and black-spotted tergites; cheliceral groove with 13 pronounced denticles; seven spinnerets. Measurements: BL 10.92, CL 4.75, CW 4.35, OL 6.60, OW 4.90; ALE > PLE > PME > AME; palp 8.30 (2.78 + 1.39 + 1.90 + 2.23), leg I 9.80 (3.05 + 1.65 + 1.95 + 1.95 + 1.20), leg II 9.21 (2.90 + 1.50 + 1.81 + 1.90 + 1.10), leg III 9.84 (2.70 + 1.70 + 1.62 + 2.35 + 1.47), leg IV 14.74 (4.00 + 1.90 + 2.70 + 4.03 + 2.11).
Female genitalia. A pair of depressions on the ventro-lateral part of genital atrium (Fig. 19C, D). Paired receptacular clusters along the anterior margin of bursa copulatrix, divided into indistinct two parts, but difficulty to separate, both with several granules, with very short genital stalks (Fig. 19A–D).
Male. Unknow.
Etymology
The species epithet, a noun in apposition, refers to the type locality.
Distribution
