Belisana longinqua sp. nov.

( Fig. 5 )

Type material. Holotype male, China: Hainan Province, Ledong County (18°44'N, 109°10'E), Jianfeng Town, 29 May 2009, Chao Zhang leg.

Etymology. The spcific name is derived from the Latin word “ longinqua ”, meaning long, and refers to the shape of the ventral apophysis on the trochanter.

Diagnosis. The new species is most similar to B. desciscens Tong & Li, 2009 , but can be distinguished by the marks on the male carapace, the procursus and the bulbal apophyses, and also by the palpal trochanter with a long ventral apophysis ( Figs 5 C–E).

Description. Male (holotype). Total length 1.43 (1.51 with clypeus), carapace length 0.56, width 0.57. Leg I lost, tibia II: 1.37, tibia III: 0.91, tibia IV: 1.46. Habitus as in Fig. 5 A, carapace pale ochre-yellow, with brown stripes radiated from center; abdomen ochre-grey, without marks. Ocular area not elevated, thoracic furrow absent. Clypeus unmodified. Sternum nearly as long as wide (0.42). Chelicerae as in Fig. 5 B, with pair of proximal rounded projections laterally, and distally a pair of long and curved apophyses. Legs yellowish without spines and curved hairs, with vertical hairs proximally on all metatarsi. Palps as in Figs 5 C–E, trochanter with long ventral apophysis; femur without hump proximo-dorsally; procursus complicated distally, with ventral membranous flap and hooked dorsal spine; bulb without hooked apophysis and tip of embolus with four branches.

Distribution. Known only from the type locality.
