Belisana zhengi Yao et al. 2015: 11 , figs 32A–D, 33A–E, 34A–C. Yao et al. 2018: 260.

Type material examined. Holotype: Male (IZCAS-Ar29617), shrub-land (21°30.364’N, 105°33.489’E, elevation 440 m), Tam Dao National Park , Vinh Phuc, Vietnam, 27 July 2008, Guo Zheng, Dinh Sac Pham, and Shuqiang Li leg. Paratypes: 4 males (IZCAS-Ar29618–29621), same data as holotype .

Other material examined. 1 male (IZCAS-Ar33065), rubber plantation (21°54.498’N, 101°16.326’E, elevation 586 ± 9 m), Xishuangbanna Tropical Botanical Garden , Menglun Nature Reserve, Menglun Town, Mengla County, Xishuangbanna , Yunnan, China, 19–26 April 2007, Guo Zheng leg. 12 males (SYNU-Ar00318–00329) and 6 females (SYNU-Ar00330–00335), Mandianzhaizi (22°7.492’N, 100°40.638’E, elevation 724 m), Nabanhe Nature Reserve, Xishuangbanna, Yunnan, China, 17 August 2012, Guo Zheng, Xue Li, and Wenyue Zhu leg. 21 males (SYNU-Ar00336–00356), Xishuangbanna Tropical Botanical Garden (( 21°54.472’N, 101°16.345’E, elevation 636 m), Menglun Town, Mengla County, Xishuangbanna , Yunnan, China, 2 August 2012, Guo Zheng, Xue Li, and Wenyue Zhu leg.

Diagnosis and description of male. See Yao et al. (2015).

Female (SYNU-Ar00330): Similar to male, habitus as in Figs 8C–D . Total length 1.57 (1.68 with clypeus), prosoma 0.56 long, 0.50 wide, opisthosoma 1.01 long, 0.73 wide; tibia I: 2.63; tibia I L/d: 47. Eye interdistances and diameters: PME-PME 0.13, PME 0.07, PME-ALE 0.01, AME absent. Sternum width/length: 0.59/0.41. Epigyne ( Figs 8A , 10E ) simple and flat, with four spine-shaped apophyses (lateral two forked) and pair of postero-lateral pockets 0.25 apart (ep in Figs 8B , 10F ). Vulva ( Figs 8B , 10F ) with relatively straight anterior arch and pair of long, laterally strongly widened pore plates.

Variation: Tibia I in the other four female specimens (SYNU-Ar00331–00334) (leg I missing in the other female specimen SYNU-Ar00335): 2.13, 2.15, 2.31, 2.35.

Natural history. The species was collected in rubber plantation by canopy fogging.

Distribution. China (Yunnan, Fig. 1 ), Vietnam (Vinh Phuc, type locality; see Yao et al. 2015: 82, fig. 61).

Remarks. We have examined the type material and other material of B. zhengi from IZCAS. The specimens from the collection of SYNU are assigned to B. zhengi , because their male morphological characters are consistent with Yao et al. ’s (2015) diagnosis and description, e.g., procursus with long, flat, dark prolatero-subdistal apophysis and leaf-shaped retrolatero-subdistal membranous flap, male chelicerae without proximo-lateral apophysis.
