SOLENYSA LONGQIENSIS GROUP

Composition: S. longqiensis Li & Song, 1992 and S. yangmingshana Tu sp. nov.

Diagnosis: Species of the S. longqiensis group are distinguished by having the carapace without conspicuous lateral lobes ( Fig. 14A ). Males are diagnosed by the horizontally U-shaped paracymbium ( Fig. 15B ), and by the well-developed anterior radical process ( Figs 11D, 15D ). The epigynal solenoid, twisting under an integument cover, is diagnostic ( Fig. 14G ).

Description: Carapace connecting laterally with sternum, but without forming conspicuous lobes around leg coxae ( Fig. 14A, B ). Other somatic characters as in the genus description.

Male palp ( Fig. 15A–F ): tibia slightly longer than patella. U-shaped paracymbium almost horizontal. Solenysa tegular triangle long. Radix strongly sclerotized with a well-developed anterior radical process, combined with anterior branch of lamella characteristica (LC 1) and anterior terminal apophysis. Other two lamella branches ribbon-like, parallel ranged. Terminal apophysis relatively compacted. Embolus less chitinized, with threaded membrane arising from distal part of embolus. Epigynum ( Figs 11E–G, 14G– H ): solenoid connecting epigynum from its ventral side and twisting anteriorly under epigynal cover. A pair of longitudinal seams located on dorsal surface. Copulatory ducts extremely short, spermathecae elongated, fertilization ducts mesially directed.

Distribution: China (Fujian, Taiwan) ( Fig. 22 ). ·

Solenysa longqiensis Li & Song, 1992: 6 , fig. 1A–G; Song, Zhu & Li, 1993: 861, fig. 17A–G; Li, Song & Zhu, 1994: 80, figs 18, 19; Song, Zhu & Chen, 1999: 204, fig. 116J–K, Q–R; Tu & Li, 2006b: 91, figs 12–20.

Types: Male holotype, CHINA: Yujiaping Town , Mt. Longqi , Jiangle County (26.7°N, 117.4°E), Fujian Province, 10.viii.1991 ( IZCAS). One male and six female paratypes, same data as holotype ( IZCAS) .

Additional material examined: CHINA: CHINA: Mt. Longqi , Jiangle County (26.70°N, 117.40°E), Fujian Province, coll. Huifu Wang, 9.ix.1990, one female ( IZCAS) .

Diagnosis: The male of S. longqiensis can be distinguished from S. yangmingshana by the truncate apex of the second branch of the lamella characteristica, with a serrated margin, by the large claw-shaped apex of the posterior branch, and by the quadrangular radix with a fist-shaped anterior radical process ( Figs 7A, 15D ). The apple-shaped epigynum is diagnostic ( Fig. 14G–H ).

Description: See Tu & Li (2006b).

Distribution: China (Fujian) ( Fig. 22 ).
