The Hypostominae are a subfamily of catfishes (order Siluriformes) of the family Loricariidae. Most members of the subfamily are restricted to tropical and subtropical South America, but there are also several species (in genera ''Ancistrus'', ''Chaetostoma'', ''Lasiancistrus'', ''Leptoancistrus'' and ''Hemiancistrus'') in southern Central America. ''Hypostomus plecostomus'', which is popular in the aquarium trade, has been introduced to several regions far from its native range. Studies conducted with representatives of some genera of Hypostominae showed, within this group, the diploid number ranges from 2n = 52 to 2n = 80. However, the supposed wide karyotypic diversity the family Loricariidae or the subfamily Hypostominae would present is almost exclusively restricted to the genus ''Hypostomus'', and the species from the other genera had a conserved diploid number. ==Taxonomy== *Ancistrini (sometimes considered a separate subfamily as Ancistrinae) * * ''Acanthicus'' * * ''Ancistrus'' * * ''Baryancistrus'' * * ''Chaetostoma'' * * ''Cordylancistrus'' * * ''Dekeyseria'' * * ''Dolichancistrus'' * * ''Exastilithoxus'' * * ''Hemiancistrus'' * * ''Hopliancistrus'' * * ''Hypancistrus'' * * ''Lasiancistrus'' * * ''Leporacanthicus'' * * ''Lithoxus'' * * ''Megalancistrus'' * * ''Neblinichthys'' * * ''Panaque'' * * ''Parancistrus'' * * ''Pseudacanthicus'' * * ''Pseudancistrus'' * * ''Pseudolithoxus'' * * ''Spectracanthicus'' * Corymbophanini * * ''Corymbophanes'' * Hypostomini * * ''Aphanotorulus'' * * ''Hypostomus'' * * ''Isorineloricaria'' * * ''Squaliforma'' * Pterygoplichthyini * * ''Pterygoplichthys'' * Rhinelepini * * ''Pogonopoma'' * * ''Pseudorinelepis'' * * ''Rhinelepis'' * ''Incertae sedis'' * * ''Leptoancistrus'' (likely Ancistrini) * * ''Peckoltia'' (likely Ancistrini) ==References== 〔 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「Hypostominae」の詳細全文を読む スポンサード リンク
