Material examined.

Holotype: ♀, China, Jiangxi Province, Ji’an City, Jinggangshan County Level City , Jinggang Mountain National Nature Reserve , Ciping Town , Dajing Village , Jingzhu Mountain , 26°30'10.8"N, 114°5'16.8"E, 1085 m, 20.XII.2015, K. Liu et al. leg . Paratype: 1♀, same data as for holotype, 26°29'42"N, 114°4'44.4"E, 1158 m, 13.VIII.2016, K. Liu et al. leg .

Etymology.

The specific name is derived from that of a similar species, L. spirellus Tang, Yin, Peng, Ubick & Griswold, 2008; adjective.

Diagnosis.

The new species is similar to L. auriculatus Tang, Yin, Peng, Ubick & Griswold, 2008 and L. spirellus Tang, Yin, Peng, Ubick & Griswold, 2008 in having coiling spermathecae (SP), but differs from them by the carapace lacking pale median band (vs. present), abdomen with three pairs of large, touching, dark brown markings (Fig. 7A ) (vs. relatively narrowed and widely separated markings). The new species can be distinguished from L. auriculatus by copulatory ducts (CD) located at posteromedian part of epigyne (vs. located anteriorly) (cf. Fig. 7C and Tang et al. 2008: fig. 2b, d). Finally, L. subspirellus sp. nov. differs from L. spirellus by spermathecae forming a tight coil (vs. loose coil) (cf. Fig. 7D and Tang et al. 2008: fig. 16d, f).

Description.

Habitus as in Fig. 7A, B . Total length 3.64. Carapace: 1.60 long, 1.49 wide, with several long setae around eye area and sublateral part of carapace. Eye sizes and interdistances: AME 0.12, ALE 0.19, PME 0.08, PLE 0.15, AME-AME 0.17, AME-ALE 0.17, PME-PME 0.30, PME-PLE 0.3 AME-PME 0.22, AME-PLE 0.17, ALE-ALE 0.71, PLE-PLE 0.87, ALE-PLE 0.26. MOA 0.37 long, front width 0.37, back width 0.47. Chelicerae with two promarginal (proximal larger, distal very small, nearly 1/3 × size of proximal one) and one (very small) retromarginal tooth. Sternum (Fig. 7B ) longer than wide, anteromedial margin procurved, lateral margins serrulate, intercoxal triangles long, almost joining carapace, posterior end arch-shaped. Abdomen (Fig. 7A, B ): 2.10 long, 1.81 wide, with abundant slender setae dorsally. Leg measurements: I 5.34 (1.62, 0.60, 1.35, 1.14, 0.63); II 5.52 (1.67, 0.67, 1.52, 1.02, 0.64); III 3.71 (1.18, 0.44, 0.97, 0.64, 0.48); IV 3.63 (1.19, 0.38, 0.88, 0.76, 0.42). Leg spination: I Fe: d2, p4; Pa: d1; Ti: d2, p4, r3, v4; Mt: p3, r3, v6; II Fe: d3, p1; Pa: d2, p1, r1; Ti: d1, p3, r2, v3; Mt: p3, r3, v4; III Fe: d3; Pa: d1; Ti: d2, p2, r1, v1; Mt: p2, r2, v1; IV: Fe: d2; Pa: d2; Ti: d3, p2, r2, v1; Mt: d2, p1, r1, v1.

Colouration (Fig. 7A, B ). Carapace reddish brown. Chelicerae, endites, and sternum reddish brown. Labium dark reddish brown. Abdomen pale white, with three pairs of large dark brown stripes, anterior one irregular, others transverse, medially with paired white guanine spots, posteriorly with a semi-oval dark brown stripe; venter with two rows of yellow spots medially.

Epigyne (Fig. 7C, D ). Epigyne 1.8 × wider than long. Anteromedian part with septum (Se) dividing atrium (At) into two oval parts. Copulatory openings (CO) located at posterior part of the fovea. Copulatory ducts (CD) almost straight, same length as spermathecal width. Spermathecae (SP) anticlockwise coiled, forming one full turn. Fertilisation duct (FD) shorter than spermathecal wide, directed anteriorly.

Male. unknown.

Comments.

At present, L. digitatus Zhang, Zhu & Tso, 2006, L. distortus Tang, Yin, Peng, Ubick & Griswold, 2008, and L. torsivus Zhang, Zhu & Tso, 2006 are known only from the males in mainland China; therefore, the new species may be conspecific with one of these three species.

Distribution.

Known only from the type locality in Jiangxi Province of China (Fig. 17 ).
