Magnocoleus is an extinct genus of beetles from the Early Cretaceous of China, between 130.0 and 125.45 Mya. The genus contains a single species, Magnocoleus huangjiapuensis, and is the only member of the family Magnocoleidae in the suborder Archostemata. Magnocoleus was first described by Chinese palaeoentomologist Hong Youchong in 1998, based on fossils of isolated elytra from the Qingshila Formation in Huangjiapu, near the Nantianmen village of Zhangjiakou in Hebei. Recent phylogenetic analyses have suggested that Magnocoleus is closely related to or placed within either Cupedidae or Ommatidae.

Metaxina is the only genus in the beetle family Metaxinidae. Its only species is Metaxina ornata. It endemic to the South island of New Zealand, where it is associated with sooty mold growing on Nothofagus trees. Both the larvae and adults are likely predaceous, feeding on insects and other arthropods. It is considered to be a member of the superfamily Cleroidea. Genetic studies have suggested that Metaxina should be considered a member of Chaetosomatidae, rather than constituting its own family.
Promecheilidae is a family of beetles in the superfamily Tenebrionoidea. Perimylopidae is considered a synonym. They are found in southern South America and associated archipelagos like South Georgia and the Falklands, New Zealand and Tasmania. Some species are associated tree ferns and moss-covered dead wood, and other forested habitats, while others are associated with peat bogs, grasslands and coastal habitats. They are probably phytophagus, feeding on lichen, moss, and other plant material.
