Taira concava Zhang, Zhu & Song, 2008

Figures 4 , 24

Taira concava Zhang et al., 2008: 506 , figs 17–21 (♂ ♀); Zhu et al. 2017: 577, figs 376A–E (♂ ♀).

Type material: Holotype ♂ (SWUC-T-AM-04-01), 1 ♀ paratype (SWUC-T-AM-04-02), CHINA, Sichuan, Mt. Emei , 29°33.506′N 103°20.830′E, 1811 m, 16.IX.2004, Z.S. Zhang, examined.

Material examined. 4 ♂ and 5 ♀ ( SWUC), Mt. Emei , Jiulinggang, 13.IV.2018, Z.S. Zhang, L.Y. Wang and Z.S. Wu .

Diagnosis. Males of this species resemble T. sulciformis males by having a groove present on the interior branch of the dorsal tibial apophysis and a similar sclerotized tegular apophysis in the palp ( Figs 4C–E ), and females resemble T. sulciformis females by having oval spermathecae in the epigyne ( Figs 4F, G ). T. concava , however, can be distinguished from T. sulciformis by the following characters: interior branch of the dorsal tibial apophysis narrower in T. concava ( Figs 4C, E ) than in T. sulciformis ; retrolateral tibial apophysis with a blunt end in T. concava , whereas degenerated in T. sulciformis ; median lobe of epigyne wider than long in T. concava ( Fig. 4F ), whereas longer than wide in T. sulciformis .

Description. See Zhang et al. (2008). Habitus, male palp and epigyne ( Fig. 4 ).

Distribution. China (Sichuan) ( Fig. 24 ).
