Multi-gene phylogeny of the primary freshwater crab genus Ptychophallus Smalley, 1964 (Pseudothelphusidae: Ptychophallinae) from the Neotropical region

Abstract

Paper summary generated by OpenAI: This study presents a comprehensive multi-gene phylogenetic analysis of the primary freshwater crab genus Pt, utilizing both mitochondrial and nuclear DNA sequences to elucidate evolutionary relationships within the group. By employing advanced phylogenetic methods, the research identifies distinct lineages and provides insights into the biogeographical distribution of these crabs. The findings reveal significant diversification patterns and highlight the importance of ecological factors in shaping the evolutionary trajectory of the genus. This work contributes to a deeper understanding of freshwater crab evolution and offers a framework for future taxonomic and conservation efforts.
