Sinopoda wuyiensis Liu, in Zhang et al. 2021: 20, fig. 9A-D (holotype female from Wuyishan National Nature Reserve, Fujian Province, deposited in College of Life Science, Hubei University LJ-202002-ZY, examined)

Material examined.

3♂, 4♀ (HUST 0004), China: Fujian: Wuyishan National Reserve, Guadun Village ; 27.58°N, 117.48°E; 16.XI.2021; Y. Zhong leg.

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 ).

Measurements of palp and legs: Palp 6.4 (1.9, 1.2, 1.4, -, 1.9), I 18.8 (5.1, 2.2, 5.5, 4.7, 1.3), II 21.9 (6.0, 2.2, 6.2, 5.9, 1.6), III 16.8 (5.1, 2.0, 4.6, 3.6, 1.5), IV 18.3 (4.6, 2.1, 5.1, 4.9, 1.6). Leg formula: II-I-IV-III. Cheliceral furrow with three anterior and four posterior teeth, and with~ 38 denticles (Fig. 4C ). Carapace deep yellowish brown dorsally, laterally and posteriorly with dark brown U-shaped pattern, with shallow fovea and radial furrows. Chelicerae deep reddish brown. Sternum yellow with brown margin. Endites and labium deep yellowish brown, with margin deep brown. Legs deep yellowish brown, covered by short spines. Opisthosoma brown dorsally, median part with four brown dots, posteriorly dark brown. Opisthosoma uniformly greyish brown with some brown patches ventrally (Fig. 4I, J ).

Palp as in Fig. 3A-C . Cymbium ~ 2 × longer than tibia in ventral view. Embolus slightly curved, arising from tegulum at nearly the 6- o’ clock-position in ventral view. Conductor curving distally, arising at 12- to 1- o’clock-position from tegulum. Spermophore almost straight. RTA arising mesially to distally from tibia, with distinct brush of stiff setae. vRTA wider than dRTA, dRTA long, in ventral view proximal part wide and tip tapering.

Leg formula: II-I-IV-III. Colouration in ethanol as in males, but opisthosoma distinctly darker dorsally and ventrally (Fig. 4K, L ; see Zhang et al. (2021) for others described).

Distribution.

Known only from the type locality (Fig. 6 ).
