Taxonomic revision and distribution of the freshwater crabs of the family Pseudothelphusidae (Decapoda, Brachyura) from Guatemala, with the descriptions of two new species and keys to the species of all genera

This dataset contains the digitized treatments in Plazi based on the original journal article Magalhães, Célio, Wehrtmann, Ingo S. (2025): Taxonomic revision and distribution of the freshwater crabs of the family Pseudothelphusidae (Decapoda, Brachyura) from Guatemala, with the descriptions of two new species and keys to the species of all genera. Zoosystema 47 (26): 581-615, DOI: 10.5252/zoosystema2025v47a26, URL: sciencepress.mnhn.fr/sites/default/files/articles/pdf/zoosystema2025v47a26.pdf ABSTRACT The taxonomic status of several of the freshwater crab species from Guatemala is somewhat confused due to old and poor descriptions of some taxa, description of several species based on female specimens, synonymization and revalidation of species and subspecies, and new combinations made by different authors.

Here, we revised the taxonomy and geographic distribution of the Pseudothelphusidae Ortmann, 1893 freshwater crabs from Guatemala, Central America. Historical material deposited in major collections of several institutions was examined, as well as previously unstudied material from the crustacean collection of the Universidad del Valle de Guatemala in Guatemala City. The pseudothelphusid crab fauna of Guatemala consists of 17 currently valid species assigned to six genera: Elsalvadoria Bott, 1967 (two species), Phrygiopilus Smalley, 1970 (five species), Potamocarcinus H. Milne Edwards, 1853 (two species), Raddaus Pretzmann, 1965 (three species), Typhlopseudothelphusa Rioja, 1953 (two species), and Zilchia Pretzmann, 1968 (three species).
