Etymology. The species is named after the type locality.
Types. Holotype: ♂ (NHMSU), PHILIPPINES: Luzon Island, Mountain Province, Sagada Town, underground river cave, large humid cave with a river, 17°05.095'N, 120°54.292'E, 1432 m, 28.V.2015, F. Ballarin & Y.C. Li leg. Paratypes: 1♂ and 14 juv. (NHMSU), same data as holotype; 1 ♂ (NHMSU), PHILIPPINES: Luzon Island, Mountain Province, Sagada Town, Eco-valley Cave, 17°05.090’N, 120°54.292’E, 1428 m, 28.V.2015, F. Ballarin & Y.C. Li leg.
Diagnosis. This species can be easily distinguished from C. lyugadinus by having a blunt embolic tip, the mesial position of patellar apophysis and the palpal tibia without trichobothrium (Fig. 2C vs. Ono, 2009: fig. 27). It differs from C. grossus and C. simboggulensis by the indistinct cervical furrow and a “C”-shaped apophysis on tegulum (Figs 1C, 2C vs. Forster, 1959: figs 98, 104, 105; Paik, 1971: fig 21, 26, 27). In C. grossus, a furcate patellar apophysis on male palp (Fig. 2C vs. Forster, 1959: fig. 104); distinguished from C. yaoi n. sp. by the shorter palpal patella with only one apophysis and the lack of trichobothrium on palpal tibia (Fig. 2C vs. 4C).
Description. Male (holotype): Somatic characters as in Figs 1 A–F, 2D. Coloration: Prosoma dark reddish brown. Opisthosoma pale green, with irregular greyish-green patches, dorsal and ventral scuta orange. Legs yellowish brown, leg I darkest. Somatic characters as in Fig. 1 A–C. Measurements: Total length 2.03. Carapace 1.38 long, 0.70 wide, 1.00 high. Clypeus 0.44 high. Sternum 0.75 long, 0.55 wide. Abdomen 1.08 long, 0.90 wide. Length of legs: I 5.48 (1.72, 0.44, 1.48, 0.84, 1.00); II 3.58 (1.08, 0.34, 0.88, 0.54, 0.74); III 2.44 (0.72, 0.24, 0.56, 0.38, 0.54); IV 3.20 (1.00, 0.30, 0.78, 0.50, 0.62). Prosoma (Fig. 1 A–F): Carapace diamond, surface finely tiny granular. Cephalic pars moderately raised. Ocular area protruded, eight eyes in four diads, lateral eyes contiguous, ALE=PLE=PME>AME. Cervical groove indistinct, thoracic fovea shallow. Chelicerae robust, with a prolateral basal tubercle, four promarginal teeth and few long, plumose retromarginal hairs (Fig. 1F). Endites constricted at median, distal serrated. Labral spur large and blunt (Fig. 1E). Labium triangular, fused to sternum. Sternum scutellate, surface rough, rugose, margins fused to carapace (Fig. 1B, E). Legs (Fig. 2D): Leg I longest, almost 4x longer than carapace. Femur I enlarged and distally sinuous, armed with one ventral row of small tubercles. Tibiae I with a spine and a cusp-like setae. 3 cusps on tarsus I. Opisthosoma (Fig. 1 A–C): Oval in dorsal view, surface covered with dense short setae. Dorsal scutum smooth, with two grey stripes and a few orange spots in lateral view. Ventral scutum encircling pedicel. Book lung covers elongated ovoid. Spinnerets situated ventrally. Palp (Fig. 2 A–C): Trochanter very long, subequal to 1/2 of femur length. Femur sinuous and long, near to 4 times patella length. Patella with a tiny apophysis. Cymbium translucent, covered with sparse long setae. Bulb simple, egg-shaped. Tegulum surface smooth, with an apical apophysis which likes an inverse “C” shape in the ventral view. Embolus bananashaped, strongly sclerotized, distally pointed.
Female. Unknown.
Natural history. The species is found in humid cave with a river.
Distribution. Known only from the type locality.
