Figs 1–4 , 39

Coelotes bicultratus Chen, Zhao & Wang 1991: 9 , figs 1–2 (female holotype and paratype from Mt. Wudangshan, Hubei, China, deposited in HUW, examined). — Song et al. 1999: 374, figs 216R–S.

Additional material examined: China, Hubei, Mt. Wudangshan, 2 females (HUW).

Diagnosis: Females of this species similar to those of L. funiushanensis and L. nitidus in having anteriorly extending spermathecal heads but the epigynal teeth of L. bicultratus separated by 1–1.5 times their width ( Figs 1, 3 ), while in the other two species they are separated by at least twice their width. The atrium of L. bicultratus is separated from the epigastric furrow by approximately 1.5 times its length ( Figs 1, 3 ) but they are separated by about the atrium length in L. funiushanensis and less than the atrium length in L. nitidus .

Description: See Chen et al. (1991) for detailed somatic description.

Female. Eye measurements (one non– type female): AME 0.13; ALE 0.20; PME 0.15; PLE 0.20; AME- AME 0.08; PME-PME 0.13; PME-PLE 0.13. Chelicerae with 3 promarginal and 2 retromarginal teeth. Epigynum with two long, strong, closely situated teeth originating from anterior margin of atrium, separated by 1.5 times their basal width in examined types ( Fig. 1 ) (in two other specimens collected from the same mountain, the epigynal teeth situated close together and separated by only about their basal width, Fig. 3 ); atrium narrow, extending transversely, widely separated from epigastric furrow by approximately 1.5 times its length; epigynal teeth reaching posterior margin of atrium; atrium extending into epigynum, forming broad copulatory duct that connects to spermathecae; spermathecal heads originating anterior of spermathecae, zigzag anteriorly, forming 3–4 loops, then extending laterally, curving back medially; spermathecae simple, oval-shaped, slightly separated ( Figs 1–4 ).

Male. Unknown.

Distribution: China (Hubei) ( Fig. 39 ).
