Figs 4–5 , 9C–D Type material. Holotype : Male (SYNU-Ar00310), near Bubeng Village ( 21°36.827’N , 101°34.847’E , elevation 690 m ), Mengla County, Xishuangbanna , Yunnan , China , 12 August 2012 , Guo Zheng, Xue Li, and Wenyue Zhu leg. Etymology. The specific name is a patronym in honor of the late Chinese arachnologist Daxiang Song; noun (name) in the genitive case. Diagnosis. The new species resembles B. fengzheni sp. nov. ( Figs 6– 7 , 9E–F , 10C–D ) having similar bulbal apophyses ( Fig. 5A ) and male chelicerae ( Fig. 5B ), but it can be distinguished by prolatero-distal membranous lamella of procursus with weakly sclerotized lamella (arrow 1 in Figs 4C , 9C ; vs. absent in B. fengzheni sp. nov. ), by procursus with two spine-shaped dorso-distal apophyses (arrows 2, 3 in Figs 4C , 9C ; vs. only one apophysis in B. fengzheni sp. nov. ), and by procursus with ventral membranous lamella (arrow 4 in Figs 4C , 9C ; vs. absent in B. fengzheni sp. nov. ). Description. Male ( holotype , SYNU-Ar00310): Total length 1.58 (1.66 with clypeus), prosoma 0.57 long, 0.55 wide, opisthosoma 1.01 long, 0.53 wide. Legs I and II missing, leg III: 5.05 (1.37 + 0.19 + 1.23 + 1.74 + 0.52), leg IV: – (2.30 + 0.20 + 2.06 + – + –). Eye interdistances and diameters: PME-PME 0.14, PME 0.06, PME-ALE 0.03, AME absent. Sternum width/length: 0.45/0.45. Habitus as in Figs 5C–E . Dorsal shield of prosoma and sternum whitish, without marks. Legs whitish, without darker rings. Opisthosoma whitish, without spots. Thoracic furrow absent. Clypeus unmodified. Chelicerae ( Fig. 5B ) with pair of proximo-lateral apophyses and pair of curved distal apophyses (distance between tips: 0.29). Pedipalp as in Figs 4A–B ; trochanter as long as wide; femur with retrolatero-proximal apophysis (arrow in Fig. 4B ); procursus ( Figs 4A–D , 9C–D ) simple proximally but complex distally, with prolatero-distal membranous lamella with weakly sclerotized lamella (arrow 1 in Figs 4C , 9C ), two spine-shaped dorso-distal apophyses (arrows 2, 3 in Figs 4C , 9C ), ventral membranous lamella (arrow 4 in Figs 4C , 9C ), retrolatero-distal membranous lamella (arrow in Figs 4D , 9D ), and retrolatero-subdistal membranous flap (f in Figs 4D , 9D ); bulb ( Fig. 5A ) with hooked apophysis and simple embolus. Legs with short vertical setae on metatarsi. Female: Unknown. Natural history. The species was collected in a seasonal rainforest by canopy fogging. Distribution. China ( Yunnan , type locality; Fig. 1 ).
