Type material.

Holotype ♂(IZCAS-Ar40399), China: Yunnan: Xishuangbanna, Mengla County, Menglun Township, XTBG, Leprosy Village, 21.8932N, 101.2883E, elevation ca 550 m, 09.V.2018, Weihang Wang leg. Paratypes 4♂4♀ (IZCAS-Ar40400-Ar40407), China: Yunnan: Xishuangbanna, Mengla County, Menglun Township, XTBG, Leprosy Village, 21.8986N, 101.2683E, elevation ca 523 m, 29.IV.2019, Zilong Bai leg.

Etymology.

The species is named after Mr. Weihang Wang, who has helped us greatly with this research; noun (name) in genitive case.

Diagnosis.

Foliabitus weihangi sp. nov. resembles F. scutigerus (Zabka, 1985) and F. longzhou Zhang & Maddison, 2012 by the long and coiled embolus, nearly forming a circle, but differs in the following: the RTA is curved towards the bulb medially in ventral view (vs. the RTA straight in ventral view in F. scutigerus and F. longzhou ); the RTA curved without a small cusp distally (vs. with a small cusp distally in F. longzhou ), the tegular lobe protrudes from the bulb (vs. indistinct in F. scutigerus and F. longzhou ); in the female, the copulatory ducts are S-shaped (vs. C-shaped in F. longzhou ).

Description.

Male (Figs 7A-C , 8C, G ). Total length 4.29. Carapace 1.94 long, 1.61 wide. Abdomen 2.35 long, 1.18 wide. Clypeus 0.05 high. Eye sizes and inter-distances: AME 0.43, ALE 0.27, PLE 0.25, AERW 1.34, PERW 1.26, EFL 1.02. Legs: I 7.25 (2.13 + 2.88 + 1.47 + 0.76), II 5.14 (1.66 + 1.78 + 1.10 + 0.60), III 5.50 (1.76 + 1.80 + 1.38 + 0.56), IV 5.61 (1.66 + 1.92 + 1.53 + 0.50). Carapace black, cephalic part with dense, green scale-like setae around eyes. Fovea longitudinal, posterior to PLEs. Clypeus yellow, covered with dense, white setae. Chelicerae black, with two retromarginal teeth and one promarginal tooth. Endites and labium dark brown. Sternum brown, covered with dark setae. Legs pale yellow, except leg I black, covered with long, dark setae. Abdomen elongated oval, dorsum black, with pale pattern; venter black with dark setae.

Palp (Fig. 7A-C ): Patella red-brown, almost as long as wide; tibia stocky, slightly wider than long, with sclerotized, hook-shaped RTA, curved towards the bulb; cymbium longer than wide, covered with long setae; bulb longer than wide, tegular lobe distinct, curved retrolaterally; embolus long and coiled, nearly forming a circle.

Female (Fig. 8A, B, D-F ). Total length 4.82. Carapace 2.04 long, 1.63 wide. Abdomen 2.78 long, 1.60 wide. Clypeus 0.06 high. Eye sizes and inter-distances: AME 0.47, ALE 0.28, PLE 0.27, AERW 1.29, PERW 1.26, EFL 1.12. Legs: I 6.16 (1.96 + 2.43 + 1.16 + 0.61), II 5.00 (1.53 + 1.96 + 1.01 + 0.50), III 5.10 (1.59 + 1.66 + 1.31 + 0.54), IV 5.71 (1.66 + 1.98 + 1.53 + 0.54). Habitus (Fig. 8D ) similar to that of male except paler. Abdomen dorsally whitish with black pattern similar to male, ventrally pale yellow, with small black triangular patch near spinnerets.

Epigyne (Fig. 8A, B ) wider than long, windows large, separated by median septum; copulatory openings at center of windows; copulatory ducts long, S-shaped; spermathecae oval; fertilization ducts well-developed, membranous, lamellar.

Distribution.

Known only from the type locality in Yunnan, China.
