Belisana lata sp. nov.

(Fig. 8)

Type material. Holotype male, China: Yunnan Province, Jinghong City (22°01'N, 100°47'E), 23 July 2000, Feng Zhang leg.; paratypes: 1Ƥ, same data as holotype.

Etymology. The specific name is derived from the Latin word “ lata ”, meaning wide, and refers to the shape of the distal apophysis on the procursus.

Diagnosis. The new species strongly resembles B. doloduo Huber, 2005, but can be distinguished by the shapes of the procursus and the bulbal hooked apophysis, and also by the palpal femur with ventral humps (Figs 8 C–E).

Description. Male (holotype). Total length 1.65 (1.95 with clypeus), carapace length 0.69, width 0.81. Leg I: 23.72 (4.61 + 0.18 + 4.46 + 12.74 + 1.73), tibia II: 3.19, tibia III: 2.09, tibia IV: 2.82; tibia I L/d: 57. Habitus as in Fig. 8 A, carapace very pale, nearly white; abdomen pale grey, without spots. Ocular area not elevated, thoracic furrow absent. Clypeus yellowish, unmodified. Sternum nearly as long as wide (0.39). Chelicerae as in Fig. 8 B, with pair of proximal small rounded projections laterally, and distally a pair of curved apophyses with tips unmodified. Retrolateral trichobothrium of tibia I at 13%; legs pale without spines and curved hairs, with vertical hairs proximally on all metatarsi; tarsus I with 15 pseudosegments, quite distinct distally. Palps as in Figs 8 C–E, trochanter with short rounded retrolateral apophysis; femur with small hump ventrally; procursus simple distally, with ventral membranous flap and wide, flat and dark apophysis; bulb with straight apophysis and simple embolus (Fig. 8 D).

Female: In general similar to male. Tibia I 2.73. Epigynum very simple externally (Fig. 8 F). Dorsal view as in Fig. 8 G, with wavy sclerotized arch anteriorly, and a pair of wide pore plates.

Distribution. Known only from the type locality.
