Pseudiberus Explained

Pseudiberus is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Bradybaenidae,^[1] inhabiting in Shandong, Henan, Hebei and Shanxi Provinces.^[2] Platypetasus Pilsbry, 1894^[3] was previously considered as synonyms of Pseudiberus, however Zhang et al. (2024) corrected it via phylogenetics based on morphology and molecules.

Taxonomy

Two subgenera Pseudiberus and Platypetasus were synonymized in the study published in 2006 by Min Wu and Gang Qi, because their genital characters and their distribution range largely overlap.^[4]

Distribution

These terrestrial snails inhabit Eastern Asia.
