Anahita wuyiensis sp. nov.

( Figs 1–11 )

Type material. Holotype ♂, CHINA, Fujian Province: Wuyi Mountains, Moshikeng (27°53′N, 117°57′E), 4 June 2013, C. Jin leg. Paratypes: 3♀, same data as holotype.

Etymology. The specific name is derived from the type locality; adjective.

Diagnosis. The species A. wuyiensis sp. nov. is similar to A. jinsi ; both with a longitudinal band on the carapace and abdomen ( Figs 1–2 , 12–13 ), epigyne with curving glandular appendage and epigynal teeth ( Figs 3–4 , 14–15 ), and palp with long striped tegular apophysis ( Figs 6 , 17 ). Anahita wuyiensis sp. nov. can be distinguished from A. jinsi by the embolus arising at the five o'clock position, and the distally round tegular apophysis in the ventral view ( Fig. 6 ) (embolus arising at three o 'clock and distally little slant tegular apophysis from the ventral view in A. jinsi , Fig. 17 ); by distally spherical and having two bends of glandular appendages on vulva ( Fig. 4 ) (distally oval and having at least three bends of glandular appendages on vulva in A. jinsi , Fig. 15 ).

Carapace ( Fig. 2 ) longer than wide, yellowish-brown, with two broad longitudinal dark-brown bands, and its edges with irregularly shaped narrow bands. Median furrow longitudinal, brown.

Opisthosoma oval, dorsum with a pale brown longitudinal median band, sides dark brown, venter spotted. Palp ( Figs 5–9 ) without RTA; embolus long, filiform, arising at five o 'clock position, running around tegulum; tegular apophysis arising from central area of tegulum, gradually widened from base to tip in ventral view, distally with pointed dorsal rim in prolateral view; conductor partly hidden by tegular apophysis in ventral view; intersegmental membrane at tibia-tarsus joint with sclerite.

Female (paratypes). Total body length 7.00–7.58; one specimen measured, total length 7.38; prosoma 3.17 long, 2.47 wide; opisthosoma 4.23 long, 2.91 wide. Carapace pattern as in male ( Fig. 1 ), but with the darker color. Diameters of eyes: AME 0.15, ALE 0.10, PME 0.22, PLE 0.23.
