Liu leg., deposited in IZCAS . Etymology. The specific name is derived from the Latin word “ parallelus ”, meaning “parallel”, and refers to the ventral view of the female copulatory ducts; adjective. Diagnosis. Females of this species are most similar to C. dong Li , sp. nov. ( Figs 70 , 72A–B ), but can be distinguished by the posteriorly located atrium (anteriorly situated in C. dong Li , sp. nov. ), and the end of copulatory ducts not extending laterally (extending laterally in C. dong Li , sp. nov. ).
