Colydiinae

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. Little is known about the biology of these beetles. Most feed on fungi, others are carnivores and eat small arthropods such as bark beetles.  Up to 9 tribes are accepted by various authors; others, however, synonymize some of these. Formerly, many additional tribes were recognized, but the Synchitini, for example, are today generally held to include a number of these tribes, and are even sometimes merged into the Colydiini.
