Etymology. The specific name is a patronym in honor of the late Prof. Fengchen Wang (1906–1978) from Norman Bethune University of Medical Sciences (now Jilin University); noun in apposition. Prof. Wang is the first Chinese zoologist to carry out a systematic national-scale survey of spiders and harvestmen.

Diagnosis. Females of this new species closely resemble those of B. baiseensis Li , sp. nov. ( Figs 4 View Figure 4 , 6A–D View Figure 6 ), but can be distinguished by the twin-looped copulatory ducts (four loops can be seen in B. baiseensis Li , sp. nov.).

Description. Female (holotype). Total length 2.95 ( Figs 51C–D View Figure 51 ). Prosoma length 1.35, width 1.00. Cephalic region width 0.58.

Chelicerae length 0.54, width 0.28. Chelicerae with distinct lateral condyles, 3 promarginal and 5 retromarginal teeth. Chelicerae, labium and gnathocoxae light brown; sternum yellow.

Epigynum ( Figs 50 View Figure 50 , 51A–B View Figure 51 ). Width 0.36. Atrium situated posteriorly of epigynal plate, touching the epigastric furrow. Copulatory ducts coiled as two loops in ventral view. Bursae enlarged, fused at base. Copulatory ducts thick, tightly twisted. The spermathecae small, transversely swollen.
