Additional: After the discovery of the fish, it was described by Hubbs & Innes in 1936. Although they realised that it was a variety of the Astyanax mexicanus(Now named fasciatus???), it was considered to be far enough developed for it to be named as a separate Genus. It was described as Anopthichthys, and the species was described as jordani.(After C.B.Jordan). This name was valid until 1969. Later insights probably redefined this Genus, and it was placed "Back" in the Astyanax Genus. The reason for the species name change to it's current name(literally:striped mexican astyanax) is that it's now considered a subspecies of Astyanax fasciatus fasciatus.
