Year: 2023

A cauda-like structure was found, firstly in Cunaxidae, and with it the new taxa Cunaxicaudinae Chen & Jin subfam. nov., and its two new genera, <i>Cunaxicaudus</i> Chen & Jin gen. nov. (type genus) and <i>Brevicaudus</i> Chen & Jin gen. nov., were erected. Cunaxicaudinae Chen & Jin subfam. nov. differs from the known members of the family Cunaxidae by the unique conspicuous cauda derived from the posterior end of the hysterosoma. The generic features of <i>Cunaxicaudus</i> Chen & Jin gen. nov.
