Type material.

Holotype: ♀, China, Hainan Province: Limushan National Forest Park (19°10'N, 109°39'E), 20 July 2020, J. Liu leg.

Diagnosis.

This new species is similar to C. volubilis sp. nov. in having the spherical spermathecae, the long and looped copulatory ducts which start from the lateral and anterior part of the atrium, extend anteriorly, then curve several times and enter the spermathecae laterally and ventrally, but can be distinguished from the latter by the following characteristics: 1. The copulatory pores are slightly separated from each other in this new species (Fig. 10D, F ), but close to each other in C. volubilis sp. nov. (Fig. 11D, F ); 2. The spermathecae are widely separated in this new species (Fig. 10D-G ), but slightly separated in C. volubilis sp. nov. (Fig. 11D-G ).

Etymology.

The specific name is derived from the Latin adjective Campanicola tauricornis , meaning ox horn-shaped, referring to the shape of the copulatory ducts in dorsal view; adjective.

Description.

Male unknown. Female (holotype): Total length 4.02. Prosoma 1.59 long, 1.52 wide, brownish black. Sternum 0.86 long, 0.95 wide, yellow, with sparse setae. Opisthosoma 2.18 long, 2.16 wide, oval, mottled, armed with sparse black setae, both dorsum and venter with irregular black plaque and white spots. Anal tubercle yellowish. Spinnerets brownish, without colulus (Fig. 10A-C ). Diameters of eyes: AME 0.09, ALE 0.07, PME 0.10, PLE 0.08. Interdistances of eyes: AME-AME 0.08, AME-ALE 0.03, PME-PME 0.07, PME-PLE 0.05. Clypeus 0.19 high, brown. Chelicerae yellow, promargin with 2 teeth. Endites brown. Labium 0.24 long, 0.08 wide, yellowish-brown, rectangular, fused with sternum. Measurements of legs: I 4.78 (1.54, 0.34, 1.00, 1.20, 0.70), II 3.32 (1.10, 0.32, 0.64, 0.76, 0.50), III 2.48 (0.84, 0.21, 0.48, 0.55, 0.40), IV 3.711 (1.27, 0.34, 0.75, 0.83, 0.53). Leg formula: I-IV-II-III. Legs yellow to brown, with brownish black ring pattern. Epigynum: atrium depression and oblate; copulatory pores distinguishable, located on anterior margin of atrium; copulatory ducts long, winding complexly, the part of copulatory ducts near copulatory pores is evidently more sclerotized than the part near spermathecae, connected with spermathecae from posterior part; spermathecae spherical, spacing obvious; fertilization ducts short, curved and tapering (Fig. 10D, E ).

Distribution.
