Liodessus
Liodessus is a genus of small diving beetles in the family Dytiscidae, tribe Bidessini. Species occur across the Americas from North America through the Andes to southern South America, with notable diversity in high-altitude wetlands and páramo ecosystems. Many species inhabit shallow, exposed pools and temporary water bodies, showing phenotypic plasticity in body form correlated with habitat permanence. The genus contains numerous species, with several new species described from the high Andes of Peru and Colombia in recent years. Taxonomic resolution relies heavily on male genital morphology.
