The Pimelodidae, commonly known as the long-whiskered catfishes, are a family of catfishes (order Siluriformes). ==Taxonomy== The family Pimelodidae has undergone much revision. Currently, it contains about 30 genera and about 90 recognized and known but unnamed species. Wikipedia lists 109 species in this family. The low-eye catfish (previously family Hypophthalmidae), and thus the genus ''Hypophthalmus'', which contains four species, was reclassified with the pimelodids.〔 This family previously included fish that are now classified under Pseudopimelodidae (previously subfamily Pseudopimelodinae) and Heptapteridae (previously subfamily Rhamdiinae).〔 This family also previously included ''Conorhynchos conirostris'', currently ''incertae sedis''. However, a molecular analysis has shown unequivocal support for monophyly of the individual families and the genus ''Conorhynchos'' into a clade called Pimelodoidea, including Pimelodidae + Pseudopimelodidae and Heptapteridae + ''Conorhynchos''. Some genera have relatively recently been synonymized. ''Merodontotus'' and ''Goslinia'' are now both included under ''Brachyplatystoma''. Also, ''Paulicea'' is now a synonym of ''Zungaro''.〔 The six main groups within Pimelodidae are ''Steindachneridion'', the ''Phractocephalus''-''Leiarius'' group, the ''Pimelodus'' group, the ''Calophysus'' group, ''Zungaro'', and the ''Sorubim'' group.〔 The ''Pimelodus'' group includes ''Pimelodus'', ''Exallodontus'', ''Duopalatinus'', ''Cheirocerus'', ''Iheringichthys'', ''Bergiaria'', ''Bagropsis'', ''Parapimelodus'', ''Platysilurus'', ''Platystomatichthys'', and ''Propimelodus''. The ''Calophysus'' group includes the five genera ''Aguarunichthys'', ''Pimelodina'', ''Calophysus'', ''Luciopimelodus'', and ''Pinirampus''. The relationships within each genus are still being studied. Most genera lack a hypothesis for monophyly. 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「Pimelodidae」の詳細全文を読む スポンサード リンク
