Belisana parallelica sp. nov.

( Fig. 6 )

Type material. Holotype male, China: Guangxi Zhuang Autonomous Region, Tianlin County (24°19'N, 106°14'E), Langping Town, 9 June 2001, Chao Zhang leg.; paratypes: 13, same data as holotype.

Etymology. The specific name is derived from the Latin word “ parallelica ”, referring to the embolus paralleling the hooked apophysis.

Diagnosis. The new species strongly resembles B. zhangi Tong & Li, 2007 , but can be distinguished by the shapes of the procursus and the embolus ( Figs 6 C–E), and also by the shape of the hooked bulbal apophysis ( Fig. 6 D).

Description. Male (holotype). Total length 1.87 (2.00 with clypeus), carapace length 0.71, width 0.73. Leg I: 17.93 (4.28 + 0.27 + 4.46 + 7.28 + 1.46), tibia II 3.14, tibia III: 1.93, tibia IV: 2.69; tibia I L/d: 51. Habitus as in Fig. 6 A, carapace pale ochre-yellow with brown margins laterally; abdomen ochre-grey, without spots dorsally. Ocular area not elevated, thoracic furrow absent. Clypeus brown, with wide and short apophysis frontally. Sternum nearly as long as wide (0.52). Chelicerae as in Fig. 6 B, with pair of proximal rounded projections laterally and pair of long and curved apophyses. Retrolateral trichobothrium of tibia I at 18%; 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 6 C–E, trochanter with short rounded retrolateral apophysis; femur with hump proximo-dorsally; procursus complicated distally, with ventral membranous flap and dorsal spine; bulb with simple embolus and hooked apophysis.

Variation. Tibia I in the other male: 4.65. Body length in the other male: 1.92.

Distribution. Known only from the type locality.
