Type material.

Holotype ♀, paratypes 2♀ and 2 juv. ♂ (NHMSU) CHINA: Hainan Province, Sanya City, Baoting County, Maogan Town, Xian’an Stone Cave, 18°35.86'N, 109°25.61'E, ca. 620 m, 24 Nov. 2014, F. Li et al. leg. Two paratypes 1 juv. ♂ and 1♀ used for sequencing, same data as for preceding, GenBank: MN211313 and MN211312.

Etymology.

Named for the Lizu people, an ethnic minority that first settled in the Hainan Province. Noun in apposition.

Diagnosis.

This new species can be distinguished from the congeners by having 5 loops of unilateral copulatory duct ( Fig. 5D ; Note: the broken first and fourth loops on the right side of copulatory duct in vulva are due to careless dissection). Moreover, it has a posterior tubercle on the abdomen ( Fig. 5A, B ), which is absent in C. anaktakun , C. discobulbus , and C. huifengi sp. nov. ( Fig. 2 A–D ; Labarque and Griswold 2014: figs 5 A–C, 6 A–C, 7 A–C).

Description.

Female (holotype): Carapace pear-shaped, black. Sternum dim, posteriorly contracted. Femora and tibiae of legs dark, other segments yellow to brown. Abdomen dark black, dorsal color lighter than venter, with posterior tubercle, covers sparse long, stiff setae ( Fig. 5A, B ). Measurements: Total length 1.72. Carapace 0.64 long, 0.61 wide. Clypeus 0.13 high. Sternum 0.40 long, 0.38 wide. Abdomen 1.23 long, 1.05 wide. Length of legs: I 2.06 (0.66, 0.26, 0.43, 0.39, 0.32); II 1.84 (0.56, 0.23, 0.38, 0.35, 0.32); III 1.42 (0.43, 0.19, 0.26, 0.29, 0.25); IV 1.81 (0.56, 0.23, 0.41, 0.34, 0.27).

Epigyne ( Fig. 5 C–E ): weakly sclerotized, nearly rectangular, black pigmentation in the central region; central pit and lateral pockets indistinct. lateral wings well developed, reniform and translucent; spermathecae small and round, separated by approximately one radius; copulatory ducts form a posterolateral auricular loop on the both sides of the lateral wings, followed by 5 loops, and finally connecting ventrally on the spermathecae ( Fig. 5D ); fertilization ducts short, arise from the dorsal-inner base of spermathecae ( Fig. 5E ).

Male. unknown.

Distribution.

Known only from the type locality ( Fig. 6 ).
