Type material.

Holotype: ♀, China, Fujian Province: Wuyishan City, Wuyi Mountain Natural Reserves (26°39'42"N, 117°56'24"E, 399 m), 28 August 2019, Y. Zhong and F.J. Liu leg. Paratypes: 1 ♀, same data as holotype.

Diagnosis.

This new species is similar to C. ferrumequina , C. tauricornis sp. nov. and C. volubilis sp. nov. in having spherical spermathecae, and long and looped copulatory ducts, but can be distinguished from them by the direction of the copulatory duct: it starts from the middle and anterior part of the atrium, extends posteriorly, then curves several times and enters the spermathecae laterally and ventrally in C. anguilliformis sp. nov. (Fig. 7E-H ); it starts from the lateral and anterior part of the atrium, extends anteriorly, then curves several times and enters the spermathecae laterally and dorsally in C. ferrumequina (Fig. 4E-H ); it starts from the lateral and anterior part of the atrium, extends anteriorly, then curves several times and enters the spermathecae laterally and ventrally in C. tauricornis sp. nov. and C. volubilis sp. nov. (Figs 10D-G , 11D-G ).

Etymology.

The specific name is derived from the Latin adjective Campanicola anguilliformis , meaning eel-like, referring to the eel-like copulatory ducts; adjective.

Anal tubercle yellow. Spinnerets surrounded with black ring, without colulus (Fig. 7A-C ). Diameters of eyes: AME 0.07, ALE 0.08, PME 0.09, PLE 0.07. Interdistances of eyes: AME-AME 0.06, AME-ALE 0.03, PME-PME 0.07, PME-PLE 0.05. Clypeus 0.16 high, yellow. Chelicerae yellow, promargin with 2 teeth. Endites yellow. Labium 0.19 long, 0.05 wide, yellow and rectangular, fused with sternum.

Leg formula: I-IV-II-III. Femur and patella light yellow, tibia, metatarsus and tarsus orange yellow. Femur, tibia and metatarsus with dark brown ring. Epigynum: atrium depression, small and oval; copulatory pores distinguishable, close to each other, located on the middle and anterior part of atrium; copulatory ducts long, winding, lightly sclerotized, connected with spermathecae from anterior-ventral part; spermathecae spherical; fertilization ducts short, curved and tapering (Fig. 7E, F ).
