Comments.

The genus Chanea was previously described in 2009 as monotypic ( Miller et al. 2009). The type species, Chanea suukyii , was known only from the type locality in the Gaoligongshan Mountains, Yunnan Province, China. This spider species mainly live in leaf litter of the subtropical evergreen broadleaf forest. According to Miller et al. (2009), the diagnostic features of this genus differs from other mysmenids by the long embolus coiled into at least 5 loops encircles the conductor and subtegulum (figs 49A, 51B; Figs 2 A–B, 3 A–B), the entire distal part of the cymbium (fig. 49A; Fig. 3 C–D), the widely spaced anterior median eyes (fig. 52B; Fig. 1A) and pair of macrosetae on the clypeus in male (fig. 52B), and the long copulatory ducts coiled around the fertilization ducts or coiled around fertilization ducts no less than 10 loops in female (fig. 49C; Fig. 4 C–D). Miller et al. (2009) mentioned that the presence of a pair of clypeal marcosetae in male is also treated as one of the generic characters. But these are lacking from Chanea voluta sp. n. (Figs 1A, 1C). Therefore, we think that the extremely long, coiled embolus and the long, coiled copulatory ducts and/or fertilization ducts may be the main diagnoses for this genus. The paired macrosetae on the clypeus in male may just be an identifying character to this type species.
