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.
Key words: Cave-dwelling,
Pseudoscorpion, Subterranean biology, Taxonomy, Troglomorphism
