Type material.

Holotype ♂ China, Yunnan, Baoshan City, Longling County, Datianba Village, Xianren Cave; 24°358.09'N, 99°037.93'E; 3 Oct. 2020; Yejie Lin Leg. (SYNU-479). Paratype 1♀: same data as holotype (SYNU-480).

Diagnosis.

This new species is similar to C. sinensis , but can be distinguished by the flat carapace (Fig. 4F ), the presence of dorsal and ventral abdominal scuta (Fig. 4A, C, E ), the unmodified cymbium (Fig. 5E ), and the short processes of tip of the bulb (Fig. 5G, H ). Camptoscaphiella sinensis has the highest point of carapace at posterior 2/3, the abdomen lacking scuta, the tip of the cymbium with a pair of enlarged tubular setae, and the tip of bulb with elongated processes ( Deeleman-Reinhold 1995: figs 1-5).

Description.

Male (holotype): Body: uniformly yellow; habitus as in Fig. 4A, C, E ; length 1.53. Carapace (Fig. 4B, F ): 0.71 long, 0.56 wide; pars cephalica slightly elevated in lateral view, surface of elevated portion and sides of pars cephalica finely reticulated. Eyes (Fig. 4B, G ): reduced, with only remnants. Clypeus (Fig. 4F, G ): margin unmodified, straight in anterior view, sloping forward in lateral view. Mouthparts (Fig. 4D, G ): chelicerae slightly divergent, anterior-median part of the endites strongly sclerotized. Sternum (Fig. 4D ): pale orange, surface finely reticulated. Abdomen (Fig. 4A, C, E ): 0.77 long, 0.48 wide; dorsal scutum covering 2⁄3 of abdomen length, 1⁄2 of abdomen width. Legs: pale orange. Palp (Figs 4H, I , 5A-H ): reddish-brown; patella extremely long club-shaped, about 4.3 times of the femur length, and 2.2 times of the bulb length; cymbium narrow in dorsal view; distal part of bulb with a rectangular prolateral process (pp), a round retrolateral process (rp) and a small ventral process (vsp).

Female (SYNU-480): Body: habitus as in Fig. 6A-C ; length 1.75. Carapace: 0.76 long, 0.61 wide. Abdomen: 1.04 long, 0.63 wide. Epigastric area (Fig. 6H, I ): surface without external features. Endogyne (Fig. 6J ): with two transverse sclerites (trs) and a median stick-shaped sclerite (ssc); apodemes (a) thread-shaped.

Etymology.

The specific name is named after Mr Yejie Lin, the collector of the type specimens; noun (name) in genitive case.

Distribution.

Known only from the type locality.
