Consolidation with Astyanax mexicanus? edit

Though there is much discussion, more recent work by Jeffery and colleagues [1][2] supports earlier work by Dowling[3] and Strecker[4] that suggests the definition of Astyanax mexicanus sp. encompases that of Astyanax jordani; i.e. Astyanax jordani is not a species in its own right, but a subpopulation of Astyanax mexicanus. I suggest Astyanax jordani page be merged with Astyanax mexicanus page.

I support this, but this would deviate from the usual taxonomic standard of FishBase and I'm open to other options. However, the current articles manage to confuse the matters completely: The full cave form (blind, colorless, etc) of Astyanax mexicanus = Astyanax jordani. Either you accept jordani as a valid species and no full cave forms of mexicanus exists, or you accept that mexicanus has full cave forms and jordani is a synonym. Instead we have several articles that all confuse them, as if they are different. I've now corrected some, but the taxonomic mess remains. RN1970 (talk) 18:56, 26 April 2017 (UTC)Reply
