Byrrhoidea is a superfamily of beetles belonging to Elateriformia that includes several families which are either aquatic or associated with a semi-aquatic habitat. Other than the superfamily Hydrophiloidea, most of the remaining Polyphagan beetles which are aquatic are in this superfamily.
Colydiinae is a subfamily of beetles, commonly known as cylindrical bark beetles. They have been treated historically as a family Colydiidae, but have been moved into the Zopheridae, where they constitute the bulk of the diversity of the newly expanded family, with about 140 genera worldwide. They are diverse for example in the Australian region, from where about 35 genera are known; in Europe, though, only 20 genera are found and many of these only with few species.
The family Archeocrypticidae is a small group of beetles with no vernacular common name, though recent authors have coined the name cryptic fungus beetles. Adults and larvae seems to be saprophagous and are often found in plant litter. Worldwide, about 10 genera and 50 species are found, most species are pantropical. Enneboeus caseyi has been recorded from the American South, Central America, and Mexico. About 20 species are found in Australia, in the genera Enneboeus,Australenneboeus and Gondwanenneboeus,Archeocrypticus,Falsoplatydema, Nothenneboeus, Sivacrypticus and Wattianus. They are largely absent from the Palearctic and Nearctic regions.
Prostomidae is a family of beetles with no vernacular common name, though recent authors have coined the name jugular-horned beetles. They are often found in dead wood. The family consist of two extant genera with about 20 species. Prostomis americanus is known from North America. Other species of Prostomis are found in Europe, Africa, the Pacific region and East Asia. Species of Dryocora are known from New Zealand, Australia and Tasmania.
Chaetosomatidae is a small family of beetles, in the superfamily Cleroidea. There are three extant genera, two of which are endemic to New Zealand with the other (Malgassochaetus) native to Madagascar. Members of this family are predaceous on wood-boring insects.
Kenocoelus is a genus of rove beetles containing a number of species, all endemic to New Zealand. It is part of the Trichonychini tribe, in the Pselaphinae subfamily of Staphylinidae.
Phloeonemus is a genus of cylindrical bark beetles in the family Zopheridae. There are at least three described species in Phloeonemus.
Microprius is a genus of cylindrical bark beetles in the family Zopheridae. There are at least two described species in Microprius.
Pseudocorticus is a genus of cylindrical bark beetles in the family Zopheridae. There is one described species in Pseudocorticus, P. blairi.
Eudesma is a genus of cylindrical bark beetles in the family Zopheridae. There is one described species in Eudesma, E. undulata.
Lyreus is a genus of cylindrical bark beetles in the family Zopheridae. There are at least three described species in Lyreus.
Megataphrus is a genus of cylindrical bark beetles in the family Zopheridae. There are at least three described species in Megataphrus.
Rhagodera is a genus of cylindrical bark beetles in the family Zopheridae. There are at least four described species in Rhagodera.
Colobicus is a genus of cylindrical bark beetles in the family Zopheridae. There are at least four described species in Colobicus.
Acolobicus is a genus of cylindrical bark beetles in the family Zopheridae. There is one described species in Acolobicus, A. erichsoni.
Monoedus is a genus of cylindrical bark beetles in the family Zopheridae. There are about eight described species in Monoedus.
Coxelus is a genus of cylindrical bark beetles in the family Zopheridae. There are about 10 described species of Coxelus.
Nematidium is a genus of cylindrical bark beetles in the family Zopheridae. There are at least three described species in Nematidium.
Eucicones is a genus of cylindrical bark beetles in the family Zopheridae. There are at least two described species in the genus Eucicones.
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.
