Figs 1 , 28–38 Type material.

Jäger leg. 28.VI.2004 . Paratypes : 2 males , 1 female ( SMF ) with same data as for holotype . Etymology. This species is named according to its similarity with Anahita fauna (Chinese [jinsi] meaning similar); term in apposition. Diagnosis. Small Ctenidae (total length male 6.5–6.6, female 7.0–8.3). Similar to Anahita fauna , A. samplexa and A. punctulata in having a long embolus and tegular apophysis in males ( Figs 31–33 ) as well as a weakly sclerotised epigyne without a clearly recognisable median septum in females ( Fig. 28 ). Females are best distinguished by the length and shape of the glandular appendages of the internal duct system: in A. jinsi spec. nov. it is long having at least three bends ( Fig. 29 ; shorter with only one bend in A. fauna [ Fig. 26 ], A. samplexa and A. punctulata ). Males of the four species are only hardly distinguishable. Length and shape of the tegular apophysis, arising point of the embolus and course of its proximal part might be diagnostic, but since an insufficient amount of material was available to judge intraspecific variation, these characters are listed in the description only. The retrolateral stout spine at the distal tibia (DS in Fig. 33 , “conical apophysis” sensu Peck 1981) might be diagnostic in comparison to A. fauna and A. samplexa . Description. Male ( paratype ).

FIGURES 35–38. Anahita jinsi spec. nov. from China, Sichuan, Baoxing (35 male, 36–38 females; 36–37 with egg sac, originally attached under a stone). Copulatory organ as in diagnosis ( Figs 28–30 ). Epigynal field with two slit sense organs, one on each side, both situated at a distance of three times their length (five times in A. fauna ). Median plate narrows anteriorly, with large lateral lobes. Copulatory openings situated anterio-medially. Copulatory ducts running a loop medially, then following lateral lobes and leading to posteriorly situated spermathecae from medio-ventral side; lateral external margin of ducts smooth, inner margin slightly undulating. Glandular appendages arising from anterior spermathecae, looping in anterior direction. Fertilisation ducts arising from spermathecae close to the point where copulatory ducts flow in spermathecae. Colour. As in male, but generally with more distinct and vivid pattern on legs. For colour of living females see Figs 36–38 . Variation. Spination patella I of other male paratype : 101. Distribution. Known only from the type locality ( Fig. 1 : 4). not belong to A. fauna . The male, however, exhibits a similarly long and slender tegular apophysis as shown for A. fauna (cf. Yoshida 2009 ).
