Caccoplectus
Caccoplectus is a genus of myrmecophilous (ant-loving) rove beetles in the family Staphylinidae, subfamily Pselaphinae. The genus was established by Sharp in 1887 and contains approximately nine described species. These beetles are associated with ant colonies, a common ecological strategy among pselaphine beetles. Most species have been described from the Neotropical region, particularly Central America.

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.

Pentodontini
rhinoceros beetles
Pentodontini is the most diverse tribe within the subfamily Dynastinae (rhinoceros beetles), containing over 100 genera distributed across multiple biogeographic regions. Most genera are restricted to a single biogeographic region. The tribe is characterized by substantial morphological diversity, with generic-level identification often relying on mouthpart morphology in females and secondary sexual characters (horns, claw modifications, antennal club length) in males.
