Ptomaphagus
Ptomaphagus is a genus of small carrion beetles in the family Leiodidae, containing at least 50 described species. Many species are obligately cavernicolous (troglobitic), restricted to cave systems in North America and Eurasia. The genus has been extensively studied as a model system for understanding cave adaptation, speciation, and evolutionary biology. Some species show advanced reproductive isolation, with hybridization experiments demonstrating reduced fecundity and viability between distinct populations.
