Etymology.

The specific name is a matronym in honour of Prof. Changmin Yin, the first to find and recognise this species, in honour of her great contribution to Chinese arachnology; noun (name) in genitive case.

Diagnosis.

The new species belongs to the Haplodrassus montanus group. The male of the new species is similar to H. guiyangensis Yan & Yu, 2021, H. hatsushibai Kamura, 2007, H. huarong Yin & Bao, 2012, and H. montanus Paik & Sohn, 1984 in having an oval tegulum, a bifurcate embolic apophysis (EA), and a hook-shaped median apophysis (MA), but it can be differentiated from H. hatsushibai and H. montanus by the absence of the basal tooth on the embolus (cf. Figs 1D View Figure 1 , 2A, B View Figure 2 vs Omelko and Marusik 2012: figs 7, 10). In addition, H. yinae sp. nov. possess 5 or 6 ridges on the embolic base (vs 6-8 ridges in H. guiyangensis ; 7 or 8 ridges in H. hatsushibai ; 6 or 7 ridges in H. huarong ; 3 or 4 ridges in H. montanus ) (cf. Fig. 1C, D View Figure 1 vs Yan et al. 2021: figs 1A, C, 2A, B and Omelko and Marusik 2012: figs 7, 8, 10, 11) and has a small tooth-like basal process (BP) directed at 9 o’clock in ventral view (vs 11 o’clock in H. guiyangensis ; a large laminar, tooth-like basal process, directed at 11 o’clock position in H. hatsushibai , H. huarong and H. montanus ) (cf. Figs 1D View Figure 1 , 2A, B View Figure 2 vs Yan et al. 2021: figs 1C, 2B and Omelko and Marusik 2012: figs 7, 10 and Yin et al. 2012: fig. 625f, g). The female of the new species resembles those of H. montanus in having pair of posterior pockets (PP) located in posterolateral part of the atrium, but it can be distinguished by the septum (Se) narrowing posteriorly (vs septum narrowing anteriorly) (cf. Fig. 3C View Figure 3 vs Omelko and Marusik 2012: fig. 20). Also, it can be separated from H. hatsushibai by posterior pockets located in posterolateral part of the atrium (vs posterior pockets located in posteromedial part of the atrium) (cf. Fig. 3C View Figure 3 vs Omelko and Marusik 2012: fig. 23) and from H. huarong by the copulatory ducts (CD) as wide as spermathecae (Sp) (vs 1/3 of spermathecal width) (cf. Fig. 3D View Figure 3 and Yin et al. 2012: fig. 625e).
