NOV. ( FIG. 8 ) Types: Male holotype , JAPAN : Hachioji , Tokyo ( 35.70°N , 139.30°E ), coll. Andoh Akihisa , 20.xii.2003 ( NSMT ). One male and two female paratypes , same data as holotype ( NSMT ) . Additional material examined: JAPAN : Tara , Mitoshi , Ibaraki ( 36.40°N , 140.40°E ), coll. A. Ando , 27.xi.2000 , three males and three females ( CNU ) . Etymology: Named after Andoh Akihisa who collected the type specimen. Diagnosis: Males of S. akihisai can be distinguished by the bifid third branch of the lamella characteristica, with a flag-shaped anterior sclerite ( Fig. 8D ). Females are diagnosed by the inversed equilateral triangular epigynal collar ( Fig. 8I ). Description: Male. Total length 1.40. Carapace 0.80 long, 0.43 wide. Abdomen 0.70 long, 0.43 wide. Chelicerae with four promarginal and two retromarginal teeth. Length of legs: I 2.44 (0.70 + 0.80 + 0.57 + 0.37); II 2.33 (0.67 + 0.73 + 0.50 + 0.43); III 1.74 (0.50 + 0.47 + 0.37 + 0.40); IV 2.16 (0.63 + 0.63 + 0.50 + 0.40). Tm I 0.20. Other somatic characters as reported in the genus description. Female. Total length 1.30. Carapace 0.75 long, 0.45 wide. Abdomen 0.65 long, 0.45 wide. Chelicerae with four promarginal and two retromarginal teeth. Length of legs: I 2.75 (0.75 + 0.90 + 0.60 + 0.50); II 2.55 (0.75 + 0.80 + 0.55 + 0.45); III 1.95 (0.60 + 0.60 + 0.40 + 0.35); IV 2.40 (0.75 + 0.70 + 0.50 + 0.45). Tm I 0.26, Tm IV absent. Other somatic characters as reported in the genus description. Other genitalic characters as reported for S. melloteei group above. Figure 9. Solenysa protrudens .

Scale bars = 0.05 mm. · Variation: Male carapace length is 0.65–0.80, total length 1.15–1.45 ( N = 3). Female carapace length is 0.72–0.75, total length 1.25–1.50 ( N = 3). Natural history: Unknown.

Type: Male holotype , JAPAN : (Ar. 2776), with label: Mt. Ibuki ( 35.20°N , 136.20°E ), Shiga Prefecture , Honshu , Japan , coll. Ryoji Oi , 11.xi.1957 ( NSMT ) . Additional material examined: JAPAN : Mitake , Omeshi , Tokyo ( 35.80°N , E 139.18°E ), coll. A. Andoh , 17.x.2004 , three males and three females ( CNU ) . Diagnosis: The male of S. partibilis is similar to that of S. abikisai sp. nov. , but differs in the bifid third branch of lamella characteristica with two long and pointed free ends ( Fig. 12B ). Epigynum is very similar to that of S. melloteei and S. akihisai but it can be distinguished by the shape of epigynal collar (see diagnosis for S. melloteei above). Description: See Tu et al . (2007) . Distribution: Japan ( Fig. 22 ).
