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.

Chelicerae yellow, with two promarginal teeth and one retromarginal tooth ( Fig. 47G ). Legs pale yellow to orange, leg I with five and two pairs of ventral macrosetae on patellae and metatarsi, respectively ( Fig. 47H ). Abdomen elongated, dorsum yellow-brown to dark brown, with two pairs of muscle depressions and transverse white stripe formed by setae medially followed by arc-shaped transverse stripes; venter pale to yellow ( Fig. 47D–E ).

PALP. Femur with triangular medio-prolateral apophysis; patellae swollen; tibia stubby, with strongly sclerotized, curved retrolateral apophysis about one-third cymbial length and pointed apically, paliform dorsal apophysis, and broad ventral apophysis; bulb swollen; MA large, strongly sclerotized, divided into three processes in ventral view; embolus forming basal disc, and spiraled to blunt tip reaches to cymbial tip ( Fig. 46 ).
