Belisana tianlinensis View in CoL sp. nov.

( Fig. 10 View FIGURE 10 )

Type material. Holotype male, China: Guangxi Zhuang Autonomous Region, Tianlin County (24°19'N, 106°14'E), 28 May 2002, Chao Zhang leg.; paratypes: 2Ƥ, same data as holotype ( MHBU).

Etymology. The species name refers to the type locality.

Diagnosis. The new species is most similar to B. lamellaris Tong & Li, 2008 , but can be distinguished by the shapes of the procursus ( Fig. 10 View FIGURE 10 C) and the chelicerae ( Fig. 10 View FIGURE 10 B), also by the longer bulbal hooked apophysis ( Fig. 10 View FIGURE 10 D) and the female genitalia ( Figs 10 View FIGURE 10 F–G).

Description. Male (holotype). Total length 2.47 (2.55 with clypeus), carapace length 0.57, width 0.91. Leg I: 18.92 (4.64 + 0.27 + 4.82 + 7.55 + 1.64), tibia II: 3.28, tibia III: 2.00, tibia IV: 3.00; tibia I L/d: 46. Habitus as in Fig. 10 View FIGURE 10 A, carapace pale ochre-yellow, brown margins laterally; abdomen ochre-grey, without spots dorsally. Ocular area not elevated, thoracic furrow absent. Clypeus brown, modified with triangular apophysis frontally. Sternum nearly as long as wide (0.60). Chelicerae as in Fig. 10 View FIGURE 10 B, with pair of proximal rounded projections laterally, and distally a pair of small curved apophyses with tips unmodified. Retrolateral trichobothrium of tibia I at 15%; legs yellowish without spines and curved hairs, with vertical hairs proximally on all metatarsi; tarsus I with 18 pseudosegments, quite distinct distally. Palps as in Figs 10 View FIGURE 10 C–E, trochanter with short rounded retrolateral apophysis; femur with small hump proximo-dorsally; procursus complicated distally, with ventral membranous flap and hooked dorsal spine; bulb with hooked apophysis and simple embolus.

Female: In general similar to male. Tibia I in 2 females: 3.00, 3.12. Epigynum simple externally ( Fig. 10 View FIGURE 10 F), frontally with dark internal semicircular shade. Dorsal view as in Fig. 10 View FIGURE 10 G, with wavy sclerotized arch anteriorly, and a pair of triangular pore plates.
