Figs 46–47, 61

Diagnosis

The male of Synagelides fanjingensis sp. nov. resembles that of S. hamatus Zhu, Zhang, Zhang & Chen, 2005 in having two tibial apophyses, but it can be easily distinguished by the RTA, which is about one-third the cymbial length in retrolateral view (Fig. 46B), whereas more than two-third the cymbial length in S. hamatus (Zhu et al. 2005: fig. 12e). The female also resembles that of S. hamatus in the general shape of the epigyne, but differs in: (1) the epigynal hood being about three times as long as wide (Fig. 47A–C), whereas about as long as wide in S. hamatus (Zhu et al. 2005: fig. 12b); (2) the copulatory openings being anteriorly located (Fig. 47A–C), whereas posteriorly located in S. hamatus (Zhu et al. 2005: fig. 12b).

Etymology

The species name is derived from the name of the type locality, Fanjing Mountain National Nature Reserve; adjective.
