''Herichthys'' is a small genus of cichlid fishes. Most are endemic to Mexico, but ''H. cyanoguttatus'' is also found in southern Texas (United States), and has been introduced to central Texas and Florida. In 2015, the genus was split, and 7 species moved into ''Nosferatu''. ==Species== There are currently 7 recognized species in this genus.〔 Separate mitochondrial DNA analyses by Husley ''et al''., 〔Hulsey, C.D., García de León, F.J. & Sánchez-Jo, Y. (2004): Temporal diversification of Mesoamerican cichlid fishes across a major biogeographic boundary.

''Journal of Biogeography, 40 (3): 579–593.''〕 and Oldfield ''et al''., support ''H. minckleyi'' as monophyletic and sister to all other ''Herichthys ''species. Moreover, molecular analysis conducted separately by López-Fernández, ''et al''.,〔López-Fernández, H., Winemiller, K.O. & Honeycutt, R.L. (2010): Multilocus phylogeny and rapid radiations in Neotropical cichlid fishes (Perciformes: Cichlidae). ''Molecular Phylogenetics and Evolution, 55: 1070–1086.''〕 and De la Maza-Benignos, ''et al''.,〔 did not support ''H. tamasopoensis'', ''H. cyanoguttatus'', ''H. teporatus'', and ''H. carpintis'' as distinct from each other. However, morphological and zoogeographical analysis by De la Maza-Benignos, ''et al''.,〔 confirmed the validity of these four species, as well as differential evolutionary trends. Analysis also supported the separation of ''Herichthys'' into three distinct geomorphological groups + ''H. minckleyi''. These are, from South to North: There are currently 7 recognized species in this genus:〔 * ''Herichthys carpintis'' (D. S. Jordan & Snyder, 1899) (Lowland cichlid) * ''Herichthys cyanoguttatus'' (S. F. Baird & Girard, 1854) (Rio Grande cichlid) * ''Herichthys deppii'' (Heckel, 1840) (Nautla cichlid) 〔 * ''Herichthys minckleyi'' (Kornfield & J. N. Taylor, 1983) (Minkley's cichlid) * ''Herichthys tamasopoensis'' Artigas Azas, 1993 (Tamasopo cichlid) * ''Herichthys tepehua'' De la Maza-Benignos, Ornelas-García, Lozano-Vilano, García-Ramírez & Doadrio, 2015 * ''Herichthys teporatus'' (Fowler, 1903) (Soto la Marina cichlid) 〔 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「Herichthys」の詳細全文を読む スポンサード リンク
