Type material. Holotype: ♂ (MHBU-ARA-00023548), CHINA: Guizhou Province, Xishui County, Linjiang Village, 6 June 2000, leg. H. Chen. Paratype: 1♀ (MHBU-ARA-00023549), same data as holotype.
Other material examined. 1♂ (MHBU-ARA-00023547), CHINA: Sichuan Province, Baoxing County, area between Wulong Village and Tuanjie Village, 30.409°N, 106.7651°E, 1042 m elev., 18 August 2019, leg. C. Zhang, W. Tan & H. Xu, SC190818-01.
Etymology. The specific epithet is in honor of Ms. Feitong Cai (Shanghai), a spider lover who has given tremendous help to the first author in collecting spider specimens.
Diagnosis. It resembles Orcevia zu sp. nov. in the body form and shape of genitalia, but the males can be distinguished by the presence of an obviously triangular process near the tip of embolus (Figs 91, 96; vs. the process is arced in O. zu sp. nov.), and the presence of sharp apophysis of embolic disc (Fig. 96; vs. AE is absent in O. zu sp. nov.); the females can be distinguished by the inverted triangular starting part of copulatory ducts (Fig. 95; vs. drop-shaped starting part of copulatory ducts in O. zu sp. nov.).
Description. Male. Habitus as shown in Fig. 89. Measurements of holotype: carapace length 2.31; abdomen length 2.96; measurements of eyes: AME 0.46, ALE 0.27, PME 0.07, PLE 0.23; measurements of legs: I 4.30 (1.35, 0.84, 0.98, 0.63, 0.50), II 3.54 (1.16, 0.65, 0.68, 0.59, 0.46), III 3.74 (1.17, 0.64, 0.71, 0.70, 0.52), IV 4.16 (1.25, 0.65, 0.95, 0.80, 0.51); leg formula 1432. Carapace dark, cephalon covered by relatively dense yellow setae, with yellow setal band at each lateral side; setae around lens of AME white; front edge of clypeus with one row of sparse white setae; dorsal abdomen with four longitudinal narrow yellow setal bands. Melanic areas on legs I–II more obvious than III–IV.
Palp (Figs 91–93): palpal bulb rather swollen, lobe-like protrusion of tegulum (LPT) short and stout; embolus straight in ventral view, with triangular extension on prolateral side close to distal part, surface of embolus rough; apophysisofembolicdisc sharp (Fig. 96); RTA wide at basal and median part, tapered towards distal part; pro-ventral hump of tibia pointing ventrally, subtriangular in prolateral view (Fig. 93).
Female. Habitus as shown in Fig. 90. Measurements of paratype: carapace length 2.16; abdomen length 3.01; measurements of eyes: AME 0.39, ALE 0.24, PME 0.07, PLE 0.20; measurements of legs: I 3.11 (0.94, 0.63, 0.68, 0.44, 0.42), II 2.94 (1.01, 0.59, 0.59, 0.40, 0.35), III 3.26 (1.03, 0.47, 0.67, 0.60, 0.49), IV 3.27 (1.02, 0.48, 0.67, 0.62, 0.48); leg formula 4312. Coloration like male but yellow setae relatively sparse.
Epigynum (Fig. 94): atria oval, close to each other and far away from genital furrow. Vulva (Fig. 95): starting part of copulatory ducts enlarged and inverted triangular; spermathecae dark, strongly sclerotized, tip of fertilization ducts almost pointing upwards.
Distribution. China (Guizhou, Sichuan).
