Liphistius kimurai Kishida, 1920: 362 (holotype: female, from Shiroyama, Kagoshima, Kyushu, Japan, collected by A. Kimura in October 1920, lost in the Science College Museum of the Tokyo Imperial University (Haupt, 1983); neotype: male, from the same locality as for the original type specimen, collected by J. Haupt on 21 March 1982, matured in August 1982, deposited in ZMH, but the neotype may be lost according to Dunlop et al. 2014).

Diagnosis.

Females of H. kimurai resemble H. higoensis females but differ by a slightly curved dorso-posterior margin of the genital area ( Fig. 7A, B ). Moreover, H. kimurai differs from all other Kyushu group Heptathela species by the following unique nucleotide substitutions in the standard DNA barcode alignment: C (26), T (98), G (191), G (194), G (206), C (215), T (251), T (278), G (293), C (362), T (366), G (443), T (449), C (452), G (506), G (521), C (527), G (548), T (572), C (599), A (615), C (638).

Description.

Females (N = 9). Carapace yellow brown; opisthosoma brown, with brown tergites close to each other; cheliceral groove with 12-14 vestigial denticles; seven spinnerets. Measurements: BL 9.30-13.80, CL 4.88-6.30, CW 4.10-5.50, OL 4.80-7.30, OW 3.45-5.40; ALE> PLE> PME> AME; palp 7.77 (2.57 + 1.50+ 1.60 + 2.10), leg I 9.15 (2.85 + 1.70 + 1.75 + 1.65 + 1.20), leg II 8.88 (2.65 + 1.65 + 1.55 + 1.88 + 1.15), leg III 9.63 (2.70 + 1.70 + 1.60 + 2.30 + 1.33), leg IV 14.08 (3.88 + 1.90 + 2.50 + 3.60 + 2.20).

Female genitalia. A pair of depressions on the ventro-lateral part of genital atrium. Paired of receptacular clusters along the anterior margin of bursa copulatrix, divided into two parts, the inner main part forming a large granulate tubercle, the outer part with several small granules ( Fig. 7 A–D ).

Male: unknown.

Remarks.

We could not examine the presumably lost neotype male ( Dunlop et al. 2014). The male is therefore unknown. The non-topotypical male described as H. kimurai by Ono (1998, 2009) is excluded here as we are not sure that the specimen was collected from the type locality although it was obtained in Kagoshima-shi.

Material examined.
