Diagnosis.
Males of this new species are similar to those of C. yujufeng Tong & Yang, 2023, but can be distinguished by lacking a cluster of black, strong setae on the labium (Fig. 6 D) vs. setae cluster present (Wang et al. 2023: fig. 5 D) and psemblous with trifurcate process (tfp, Fig. 7 D, K) vs. with semicircular, prolateral rim and trifurcate ventral process (Wang et al. 2023: fig. 6 E, J). Females of the new species are similar to those of C. zayu sp. nov., but can be distinguished by the fusiform median plate (Fig. 8 H) vs. pear-shaped (Fig. 11 H) and the long copulatory duct, which extends beyond the postgastric scutum (Fig. 8 I) vs. just reaching groove between posterior spiracles (Fig. 11 I).
Description.
Male (holotype). Body: uniformly colored, yellowish brown; habitus as in Fig. 6 A, C, E; length 1.75. Carapace (Fig. 6 B, F): 0.84 long, 0.68 wide; pars thoracica strongly elevated in lateral view, entire surface finely reticulated. Eyes (Fig. 6 B, G): ALE: 0.07; PME: 0.05; PLE: 0.04; ALE circular, PME oval, PLE oval; posterior eye row straight from above, procurved from front; ALE separated by less than one radius. Clypeus (Fig. 6 F, G): margin unmodified, straight in front view, sloping forward in lateral view. Mouthparts (Fig. 6 D, G): chelicerae unmodified; anterior-median part of the endites slightly sclerotized. Sternum (Fig. 6 D): as long as wide, with pointed anterolateral bumps. Abdomen (Fig. 6 A, C, E): 0.91 long, 0.53 wide; oval, scuta pale orange; dorsal scutum covering about 3 / 4 of abdomen length, about 2 / 3 of abdomen width, fused to epigastric scutum; postgastric scutum small, covering about 1 / 2 of abdominal venter. Palp (Fig. 7 A – L): reddish brown; patella extremely long club-shaped, length / width = 3.41, about 5.5 times longer than femur, and 2.5 times longer than bulb; cymbium (length / width = 1.92) narrow in dorsal view; psembolus with trifurcate process (tfp), ventral outgrowth (vo) and small retrolateral fold (rlf).
Female (SYNU -1100). As in male except for the following. Body: habitus as in Fig. 8 A, C, E; length 1.94. Carapace: 0.83 long, 0.74 wide. Eyes: ALE 0.07; PME 0.05; PLE 0.06. Abdomen: 1.11 long, 0.76 wide. Postgaster (Fig. 8 F, H): with rounded anterior sclerite (as) and fusiform median plate (mp). Endogyne (Fig. 8 I): copulatory duct (cd) long, narrow, sinuous with tip well beyond postepigastric scutum; apodemes (ap) slender.
Etymology.
The specific name, derived from Latin word trifoliatus, refers to the three-forked processes on the distal part of the bulb; adjective.
Distribution.
Known only from the type locality.
