Looks can deceive: a troglomorphic but not troglobitic Attaleachernes species (Pseudoscorpiones: Chernetidae) from the eastern Amazon

A new species of pseudoscorpion, Attaleachernes spelaeus sp. nov., is described, featuring detailed morphological characteristics, diagnostic traits, and illustrations that distinguish it from its congener. Additionally, a comparative discussion on the genus is provided, including a description of the species’ habitat. This new species represents the second recorded occurrence of the genus Attaleachernes.

Recommendations are proposed for future research on A. spelaeus sp. nov., highlighting the need for further exploration of its characteristics and ecology.
