Yao leg., deposited in IZCAS . Paratypes . 6 males , 7 females , same data as holotype, deposited in IZCAS . Etymology. The specific name is derived from the Latin word “ funarius ”, meaning “of a rope”, and refers to the shape of the copulatory ducts; adjective. Diagnosis. Males of this new species are similar to B. yizhouensis Li , sp. nov. ( Figs 57–61 ), but can be distinguished by the 8-o’clock position of the base of the embolus (originating approximately at the 10-o’clock position in B. yizhouensis Li , sp. nov. ). Females of this new species are similar to B. tongyanfengi Li , sp. nov. ( Figs 45–49 ), but can be distinguished by the copulatory ducts twisted as two short ropes in ventral view (copulatory ducts twisted loosely and irregularly in B. tongyanfengi Li , sp. nov. ).
