Name
Heptathela kanenoi Ono, 1996 – Wikispecies link – Pensoft Profile
- Heptathela kanenoi Ono, 1996: 158 (holotype: male, from Mikyo, Amagi-cho, Tokunoshima, Kagoshima-ken, Japan, collected by M. Owada and S. Kaneno on 2 November 1992, deposited in NMNS, examined); Ono 2009[1]: 80.
Diagnosis
Males of H. kanenoi can be distinguished from those of all other Amami group Heptathela species by lacking a spiniform conductor apex (Fig. 10G, I). Females of H. kanenoi can be distinguished from those of all other Amami group Heptathela species by the inner receptacular clusters larger than the outers (Fig. 10B, C). H. kanenoi can also be diagnosed from all other Amami group Heptathela species by the following unique nucleotide substitutions in the standard DNA barcode alignment: A (35), G (38), C (71), C (125), C (224), G (278), T (281), C (288), T (332), G (359), C (396), C (410), G (443), T (449), A (512), C (533), G (557), C (560), C (623), T (641).
Description
Males (N = 6). Carapace yellow brown; opisthosoma brown, with dark-spotted tergites close to each other; cheliceral groove with 10–13 vestigial denticles; 7 spinnerets.

Palp. Prolateral side of paracymbium unpigmented and unsclerotised, numerous setae and spines at the tip of paracymbium (Fig. 10D–F). Contrategulum with serrated margin (Fig. 10G–I). Tegulum with dentate dorsal extension of terminal apophysis (Fig. 10J) and blunt tegulum terminal apophysis (Fig. 10I, J). Conductor base wide and rugose, with several folds and each fold with an apical tooth (Fig. 10G–J). Embolus with a wide and flat opening, the distal part slightly sclerotised, and saddle-shaped in the prolateral view (Fig. 10H–I).
Females (N = 11). Carapace and opisthosoma colour as in male; cheliceral groove with 12–14 pronounced denticles; tergites similar to male; seven or eight spinnerets. Measurements: BL 8.30–12.90, CL 4.30–6.28, CW 3.60–5.40, OL 4.38–6.50, OW 3.70–6.20; ALE > PLE > PME > AME; palp 7.00 (2.50 + 1.35 + 1.55 + 1.60), leg I 7.75 (2.30 + 1.25 + 1.60 + 1.50 + 1.10), leg II 7.60 (2.60 + 1.10 + 1.50 + 1.50 + 0.90), leg III 8.35 (2.45 + 1.50 + 1.10 + 2.00 + 1.30), leg IV 12.15 (3.40 + 1.50 + 2.25 + 3.20 + 1.80).
Female genitalia. A pair of indistinct depressions on the ventro-lateral part of genital atrium. Paired receptacular clusters along the anterior margin of bursa copulatrix, divided into two parts, the inners larger than the outers, without genital stalks (Fig. 10A–C).
