Figs 13–16

Differential diagnosis

The new species resembles Indophantes halonatus ( Li & Zhu, 1995) in having the similar radix and pit hook in male palp and epigyne with quadrangular pseudoscape ( Figs 13A–C , 14–15A ; Tu, Saaristo & Li 2006: fig. 29), but can be distinguished by: the lateral margin of distal arm of paracymbium with two small lobes in new species ( Fig. 13B ), whereas with one lobe in I. halonatus (Tu, Saaristo & Li 2006: fig. 28). Thumb tomb-shaped in new species ( Fig. 14A ), whereas serrated margin with pointed tip in I. halonatus (Tu, Saaristo & Li 2006, fig. 31). Spermathecae round in new species ( Fig. 15D ), whereas lobed in I. halonatus (Tu, Saaristo & Li 2006: figs 34–35).

Etymology

The epithet is derived from the type locality.
