Anacaena is a genus of water scavenger beetles in the subfamily Hydrophilinae. It is an extant genus but there is at least one fossil species.
These species belong to the genus Anacaena. More than 100 species are included in this genus worldwide. [2]

Zopheridae is a family of beetles belonging to Tenebrionoidea. It has grown considerably in recent years as the members of two other families have been included within its circumscription; these former families are the Monommatidae and the Colydiidae, which are now both included in the Zopheridae as subfamilies or even as tribe of subfamily Zopherinae. Some authors accept up to six subfamilies here, while others merge all except the Colydiinae into the Zopherinae.
Corylophidae is a family of minute hooded beetles, sometimes called minute fungus beetles, in the superfamily Coccinelloidea. There are about 18 genera and at least 120 described species in Corylophidae. They feed on microfungi such as molds, and are often found associated with bark, as well as in leaf litter and other decaying vegetation. In older literature, the family name was often given as Orthoperidae.
Erotylidae, or the pleasing fungus beetles, is a family of beetles belonging to Cucujoidea containing over 100 genera. In the present circumscription, it contains 6 tribes and 10 subfamilies. In other words, the narrowly circumscribed Erotylidae correspond to the subfamily Erotylinae in the definition sensu lato. There are doubts on the monophyly of lower ranked taxa within Erotylidae, with further phylogenetic studies requiring better sampling and studies of unexplored character sets, for example the metendosternite and penile flagellum, which are generally lacking detailed morphological studies within the Coleoptera literature. The Eroytlina taxonomy is based on traits such as their different colors and not off morphological differences like mouthparts, thorax, and abdominal terminalia (Pecci-Maddalena).
Lasioderma is a genus of beetles in the family Ptinidae. As of 1990, there were over 50 species in the genus.
Stagetus is a genus of death-watch and spider beetles in the family Ptinidae. There are at least 20 described species in Stagetus. They eat fungi.
Hydrochus is the only living genus of beetle in the family Hydrochidae, which belongs to the superfamily Hydrophiloidea, and was formerly treated as a subfamily of Hydrophilidae. Hydrochus includes about 180 species, which are found worldwide. The name "Hydrochus" has also been used for a fly genus in the family Dolichopodidae, but this is a junior subjective synonym of the genus Rhaphium.
Beetles of the genus Helichus are found worldwide apart from in Australia and Antarctica. Adults reach 1–8 millimetres (0.04–0.31 in) long and live in aquatic or riparian environments. The larvae are land-dwelling which may be unique in water living insects.
Enochrus, a genus of water scavenger beetles, is the third-largest genus of hydrophilids with 229 species in six subgenera worldwide.
Medon is a genus of rove beetles in the family Staphylinidae. There are at least 60 described species in Medon.
Macrorhyncolus is a genus of true weevils in the family of beetles known as Curculionidae. There are about five described species in Macrorhyncolus.
Mycetoporus is a genus of crab-like rove beetles in the family Staphylinidae. There are at least 70 described species in Mycetoporus.
Omalium is a genus of ocellate rove beetles in the family Staphylinidae. There are at least 70 described species in Omalium.
Tenebroides is a genus of bark-gnawing beetles in the family Trogossitidae. There are at least 20 described species in Tenebroides.
Mesites is a genus of true weevils in the family of beetles known as Curculionidae. There are at least 30 described species in Mesites.
Aciliini is a tribe of predaceous diving beetles in the family Dytiscidae. There are 7 genera and at least 69 described extant species in Aciliini, along with 5 fossil species.
Trigonurus is a genus of rove beetles in the family Staphylinidae, the only family of the subfamily Trigonurinae. There are about nine described species in Trigonurus, found in the Holarctic.
Synchitini is a tribe of cylindrical bark beetles in the family Zopheridae. There are about 19 genera and at least 40 described species in Synchitini.
Mitostylus is a genus of broad-nosed weevils in the beetle family Curculionidae. There are about seven described species in Mitostylus.
Trachyphloeosoma is a genus of broad-nosed weevils in the beetle family Curculionidae. There are about five described species in Trachyphloeosoma.
Nanus is a genus of true weevils in the family of beetles known as Curculionidae. There are about six described species in Nanus.
