New Neotropical Pseudochthonius
(Pseudoscorpiones: Chthoniidae) from Northeastern Brazil: Insights into
Brazilian troglobiont Pseudoscorpions
We describe two new neotropical troglobitic pseudoscorpions from Brazil: Pseudochthonius aware sp. nov. and Pseudochthonius itakuatiara sp. nov. These species show typical subterranean adaptations, including depigmentation, elongated appendages, and, in P. aware sp. nov., the absence of eyes. This study also addresses the distribution of troglobitic Pseudochthonius species in Brazil, such as Pseudochthonius biseriatus Mahnert 2001, and Pseudochthonius strinatii
Beier, 1969, the latter being the first troglobiont pseudoscorpion
recorded in Brazil. Their wide distribution suggests they may be highly
cryptic affinis species,
necessitating a revision of the taxonomic characters used in their
original descriptions, for posterior settling. Further revisions and
molecular studies of the genus is needed as troglobiont species
distribution understanding are critical for cave conservation and
protection. This underscores the importance of accurate identification
and description not only for the species conservation and threat
analysis but also for habitat preservation.
