Diagnosis.
Males of
S. wuyiensis
can be distinguished from other
Sinopoda
species by the combination of the following characters: bases of the tegulum with a distinct sub-triangular protrusion, embolic apophysis reduced, distinctly narrower and shorter than the embolus, and the dRTA about twice as long as the vRTA in ventral view. Females of
S. wuyiensis
may be recognised by the following combination of characters: epigynal field almost fusiform, lateral lobes fused without visible seam, with their anterior and posterior margins almost parallel, and glandular appendages laterad, as wide as posterior part of spermathecae (Fig.
3
).
