Eye (Fig. 2 C) sizes and interdistances: AME 0.12, ALE 0.18, PME 0.18, PLE 0.18; AME – AME 0.06, AME – ALE 0.08, PME – PME 0.12, PME – PLE 0.17, ALE – PLE 0.04. MOA: 0.33 long; 0.25 front width, 0.43 back width. Clypeus height 0.24. Chelicerae with five promarginal and six retromarginal teeth. Leg measurements: I 11.35 (3.41, 1.33, 2.47, 2.53, 1.61); II 9.71 (2.73, 1.72, 2.01, 2.27, 1.42); III 9.02 (2.47, 1.21, 1.87, 2.27, 1.21), IV 12.84 (3.87, 1.33, 2.87, 3.41, 1.37). Leg formula: 4123.

Copulatory duct (CD) convoluted, present anteriorly; spermathecal head (SH) thick, drop-shaped, points to a 45 ° angle (Fig. 3 E); spermatheca (S) subcircular; fertilisation duct (FD) conspicuous, horn-like, extending laterally (Fig. 3 E).

Variation: Total length in females (n = 4) varies from 7.88 to 10.65.

Diagnosis

The new species resembles Coelotes mastrucatus Wang, Yin, Peng & Xie, 1990 (Zhu et al. (2017): figs. 83 A-E) in having the similar abdomen pattern in the both sexes. The male can be distinguished by: (1) lateral tibial apophysis (LTA) half the length of the tibia (Fig. 3 B), vs. 2 / 3 of the length of the tibia (Zhu et al. (2017): fig. 83 E); (2) conductor (C) bends to the back and hook-shaped (Fig. 3 C), vs. conductor first bends backward and then upwards and and blunt end (Zhu et al. (2017): fig. 83 E); (3) dorsal apophysis of conductor (CDA) bends upwards and fan-shaped (Fig. 3 B) vs. CDA inwardly curved and obtusely pointed end (Zhu et al. (2017): fig. 83 D). The female can be distinguished by: (1) epigynal tooth (ET) point to the inner edge of copulatory opening (Fig. 3 D) vs. pointing to copulatory opening (Zhu et al. (2017): fig. 83 A); (2) spermathecal head (SH) drop-shaped and the length not exceeding spermatheca (S) (Fig. 3 E) vs. SH small and located above the spermatheca (Zhu et al. (2017): fig. 83 B).

Etymology

The specific name is dedicated to Haofei Fan for his contribution to the collection of specimens; it is a noun in the genitive case.

Distribution

Known only from the type locality in Guangxi Zhuang Autonomous Region, China (Fig. 4).

Biology

This species mainly lives under rocks in evergreen broad-leaved forests and frequently searches for prey around cave openings.
