Two new pseudoscorpion species, Pseudochthonius aware sp. nov. and Pseudochthonius itakuatiara sp. nov., are herein described. These species exhibit distinct characteristics that differentiate them from other congeneric species, including variations in chelal and cheliceral dentition, coxal chaetotaxy, and measurements. In addition to taxonomic details, we provide ecological observations for each species, identify potential threats, propose avenues for future research, and offer a key for distinguishing the Pseudochthonius species found in Brazil.
