Cyprinella lutrensis ssp. blairi (Hubbs)

Maravillas Red Shiner (Cyprinella lutrensis ssp. blairi)

The Maravillas Red Shiner was restricted to the Garden Springs and the Pena Colorado Creek, which are a part of the Maravillas Creek drainage, a tributary of the Rio Grande in the Big Bend region of Texas, USA.

This subspecies reached a length of about 4,4 cm

The Maravillas Red Shiner disappeared in the late 1950s due to competition with introduced, invasive Plains Killifish (Fundulus zebrinus Jordan & Gilbert).

***

Some biologists consider the Maravillas Red Shiner synonymous with the nominate form.
