Description

Male (Holotype). Body: pale yellow, abdomen paler; habitus as in Fig. 5 A, C and E; length 1.37. Carapace (Fig. 5 B and F): 0.64 long, 0.56 wide; pars cephalica slightly elevated in lateral view, surface of elevated portion and sides of pars cephalica finely reticulate. Eyes (Fig. 5 B and H): ALE 0.057; PME 0.049; PLE 0.049; posterior eye row procurved from both above and front; ALE separated by less than one radius. Clypeus (Fig. 5 B, F and H): margin unmodified, straight in front view, sloping forward in lateral view. Mouthparts (Fig. 5 G and H): chelicerae unmodified; with a cluster of black, strong setae on the labium. Sternum (Fig. 5 G): as long as wide, surface finely reticulate, with pointed anterolateral bumps. Abdomen (Fig. 5 A, C and E): 0.73 long, 0.58 wide; dorsal scutum covering ca. 2⁄3 of abdomen length, 1/3 of abdomen width, anteriorly fused to epigastric scutum; postepigastric scutum small, just near epigastric furrow. Legs: yellowish-white. Palp (Fig. 6 A-K): reddish-brown; patella extremely long club-shaped, length/width = 2.76, ca. 3.7 times the femur length and 2.1 times the bulb length; cymbium narrow in dorsal view; bulb distal part with semicircular, prolateral rim (spr), three-forked ventral appendices (va) and distally with small retrolateral fold (rlf) and several outgrowths.

Female: unknown.

Diagnosis

This new species is similar to Camptoscaphiella yinglefeng sp. nov., but can be distinguished by the dorsal scutum ca. 1/3 of abdomen width (Fig. 5 A), vs. 2⁄3 of abdomen width (Fig. 2 A), the ventral appendices of bulb shorter than retrolateral fold (Fig. 6 E and F), vs. longer than retrolateral fold (Fig. 3 F and G) and lacking the ventral process (Fig. 6 J and K) of bulb, vs. present (Fig. 3 I and J).

Etymology

The specific epithet is derived from the type locality; noun in apposition.

Distribution

Known only from the type locality.

Comment

Camptoscaphiella hudie sp. nov. (male unknown) and Camptoscaphiella yujufeng sp. nov. (female unknown) were collected from the same locality, Cangshan Mountain. The dorsal abdominal scutum of C. hudie is very small and narrow, quite different from that of C. yujufeng (compare Fig. 1 A and Fig. 5 A). This suggests that they are most likely different species.
