Taibaishanus nankangensis sp. nov. (DZĖẊƠƜƦ) Figures 302–304

Types. Holotype ♂, CHINA, Yunnan, Lonhyang County, Nankang, 24.81667ºN, 98.78333ºE, 2100m, 4–7 November 1998, Charles Griswold, D. H. Kavanaugh and Chun-lin Long leg. (98–NK).

Etymology. This epithet derives from the type locality.

Diagnosis. The new species can be distinguished from the Taibaishanus elegans Tanasevitch, 2006 by the male cephalic region with tomb-shaped cephalic lobe in T. nankangensis sp. nov. (Fig. 303A), whereas male cephalic lobe absent in T. elegans (Tanasevitch, 2006, fig. 68). Dorsal tibial apophysis tongue-shaped and the retrolateral tibial apophysis tip without depression in T. nankangensis sp. nov. (Fig. 302B–D), whereas dorsal tibial apophysis somewhat triangular and the retrolateral tibial apophysis tip with depression in T. elegans (Tanasevitch, 2006, figs 69, 71). Embolus tip fine in T. nankangensis sp. nov. (Fig. 302A, D), whereas broad with a small round outgrowth in T. elegans (Tanasevitch, 2006, figs 70, 73). Radix slightly curved, longer than wide in T. nankangensis sp. nov. (Fig. 302A–D), whereas U-shaped in T. elegans (Tanasevitch, 2006, figs 70, 73).

Palp (Fig. 302A–D). Patella shorter than tibia, ventrally slightly curved; tibia with two apophyses; dorsal tibial apophysis tongue-shaped with blunt end and the retrolateral tibial apophysis with long spines, distally curved with notched tip. Paracymbium U-shaped, distal arm tip hook-shaped.Protegulum membranous, extending forward. Radix slightly curved, longer than wide. The embolic division apophysis sclerotized, long, S-shaped apically. Embolus sinuous, tip fine and thin, forming a circle apically.

Female. Unknown.
