Sphaerius is a genus of beetles in the family Sphaeriusidae, comprising 18 extant species. It is one of the two extant genera in the family, the other being Bezesporum. They are typically found along the edges of streams and rivers, where they feed on algae; they occur on all continents except Antarctica. Three species occur in the United States.

Triamyxa is an extinct genus of myxophagan beetle in the monotypic family Triamyxidae from the Carnian stage of Late Triassic, approximately 230 million years ago. It was found in the Keuper Claystone of Poland. The type species is Triamyxa coprolithica and it was identified from specimens found in the coprolite ZPAL AbIII/3520, likely belonging to the dinosauriform Silesaurus opolensis. Because Triamyxa specimens were found inside coprolites, this may offer a new method of finding insect fossils aside from amber. It is currently the oldest known member of Myxophaga. It was interpreted as

Lepicerus is a genus of myxophagan beetles containing three described species in the family Lepiceridae; it is the only extant genus in the family, with another genus, Lepiceratus only known from fossils. Extant species occur in the Neotropics, from Mexico south to Venezuela and Ecuador. Fossils referrable to the genus are known from the early Late Cretaceous of Southeast Asia.
