Etymology.

The specific name of this new species is dedicated to the Chinese arachnologist Prof. Zhangfu Chen in honor of the first description of a Cicurina species in China.

Diagnosis.

The male of this new species is similar to that of C. avicularia Li & Wang, 2017 ( Li and Wang 2017: figs 62 A, B, 63 A, B, 65 A – D, 66 E) in having the similar shaped retrolateral tibial apophysis, and the slender and filiform embolus, but differs by the weakly bifurcated conductor end (Figs 6 A, B , 7 B – D ) (vs. with strongly bifurcated in C. avicularia ).

Description.

Male holotype (Fig. 7 A ) total length 2.65. Prosoma 1.24 long, 0.92 wide; opisthosoma 1.37 long, 0.95 wide. Carapace pyriform and pale yellow, with sparse setae. Eye sizes and interdistances: AME 0.05, ALE 0.06, PME 0.06, PLE, 0.06; AME – AME 0.03, AME – ALE 0.02, PME – PME 0.07, PME – PLE 0.05, ALE – PLE 0.02. MOA 0.15 long, anterior width 0.12, posterior width 0.17. Clypeus height 0.09. Chelicerae with three promarginal and six retromarginal teeth. Leg measurements: I 3.26 (0.94, 1.11, 0.67, 0.54); II 2.93 (0.86, 0.98, 0.60, 0.49); III 2.69 (0.80, 0.79, 0.62, 0.48); IV 3.33 (0.95, 1.08, 0.81, 0.49). Leg formula: 4123. Opisthosoma oval, pale yellow and sparsely hairy, with distinct patterns.

Palp (Figs 6 A, B , 7 B – D ). Retrolateral tibial apophysis wide, with a single fold and rounded end. Embolus slender and filiform, originating at approximately 6 - o’clock position, with the anterior part extending along the long groove of the conductor. Conductor short and strong, with a weakly bifurcated end.

Female. Unknown.

Variation.

Males (N = 3) total length 2.65–2.77.
