Differential diagnosis

Synagelides xingdouensis sp. nov. can be easily distinguished from all other congeners by: male palp has three tibial apophyses in S. xingdouensis sp. nov. whereas none, one or two tibial apophyses in other congeners; spermathecae are mainly anterior to copulatory ducts and about three-fourth as long as epigynum in S. xingdouensis sp. nov., whereas mainly posterior to copulatory ducts and shorter than half the epigynal length in all other congeners.

Etymology

The species name comes from the type locality; adjective.

Abdomen ( Fig. 16 D–E) oval; dorsum brown, with two pairs of muscle depressions and a transverse white band followed by an indistinct transverse yellow patch; venter gray-white. Palp ( Fig. 15 A–D): patella about 1.5 times longer than wide; retrolateral tibial apophysis tapering to a slightly pointed tip; intermediate tibial apophysis triangular, transparent apically; dorsal tibial apophysis tapering,digitiform in dorsal view; embolus short, broad and flattened antero-medially and abruptly narrowed posteriorly; median apophysis bifurcated terminally in retrolateral view.
