Diagnosis.

This new species can be distinguished from other Campanicola species, in the female, by the position of the copulatory pores: located on the lateral and posterior part of atrium in this new species while located anteriorly in other Campanicola species; and the relative position of the copulatory ducts to the spermathecae: partial copulatory ducts overlap the posterior-ventral half of the spermathacea in this new species (Fig. 8E, G ), but nearly all copulatory ducts are below the spermathecae in other Campanicola species.

Etymology.

The specific name is derived from the Latin adjective Campanicola falciformis , meaning doubly falcate, referring to the falcate copulatory ducts in ventral view; adjective.

Description.

Male unknown. Female (holotype): Total length 2.29. Prosoma 0.92 long, 0.79 wide, brown, with dark brown margin. Sternum 0.49 long, 0.47 wide, yellow, peltate, with sparse setae. Opisthosoma 1.45 long, 1.38 wide, yellowish-brown, dorsum center with an angle bracket-shaped pale-yellow stripe either side of the midline, dorsum posterior with lateral pale-yellow stripe, and many bright white spots are distributed in the stripes (Fig. 8A ). Anal tubercle yellow. Spinnerets surrounded with blackish brown ring, without colulus. Diameters of eyes: AME 0.06, ALE 0.09, PME 0.10, PLE 0.10. Interdistances of eyes: AME-AME 0.08, AME-ALE 0.03, PME-PME 0.08, PME-PLE 0.04. Clypeus 0.16 high, yellow. Chelicerae yellow, promargin with 2 teeth. Endites orange yellow. Labium 0.20 long, 0.06 wide, yellow and rectangular, fused with sternum. Measurements of legs: I 3.67 (1.17, 0.29, 0.79, 0.93, 0.49), II 2.52 (0.80, 0.25, 0.49, 0.58, 0.40), III 2.03 (0.62, 0.29, 0.35, 0.38, 0.39), IV 3.01 (1.01, 0.27, 0.65, 0.66, 0.42). Leg formula: I-IV-II-III. Femur, patella, tibia and metatarsus light yellow, tarsus yellow. Femur, tibia and metatarsus with dark brown ring. Epigynum: atrium depression and oval; copulatory pores apparent, widely separated with each other, located on the lateral and posterior part of atrium; copulatory ducts long and winding, the part of copulatory ducts near copulatory pores is more sclerotized than the part near spermathecae, the part near spermathecae overlaps half of the spermathecae, and connected with spermathecae from posterior and lateral part; spermathecae nearly spherical to oval; fertilization ducts short, tapering gradually (Fig. 8E, F ).
