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.〔 (2002): ().

Most feed on fungi, others are carnivores and eat small arthropods such as bark beetles. 〔 (1987): ''Beetles of Australia''. Angus and Robertson, North Ryde, New South Wales. ISBN 0-207-15352-3〕 ==Systematics and taxonomy== 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.〔 The tribes are: * Acropini * Adimerini * Colydiini Erichson, 1845 * Gempylodini * Nematidiini * Orthocerini Blanchard, 1845 (= Sarrotriini Billberg, 1820 (nom. rej.)) * Rhagoderini * Rhopalocerini * Synchitini Erichson, 1845 (sometimes in Colydiini) Delimitation of the Colydiinae against the other lineages of Zopheridae is usually unproblematic. The only significant case of dispute may be the Pycnomerini, which is a small lineage of Zopheridae ''incertae sedis'' and was formerly considered an independent family like the "Colydiidae". That treatment is almost certainly wrong, but whether these beetles should be placed in Zopheridae as an additional subfamily Pycnomerinae, or treated as tribe Pycnomerini – and if the latter, whether they are better included in the Colydiinae or the Zopherinae – is still disputed. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Colydiinae」の詳細全文を読む スポンサード リンク
