最初命名為 Etheostoma segrex:
- Norris, Steven & R.R. Miller. 1997. "Two new species of Etheostoma (Osteichthyes: Percidae) from Central Coahuila, northern México". Ichthyological Explorations of Freshwaters. 8(2):159-176 (ffm00339)
保育: Etheostoma segrex 尚未被國際自然保育聯盟列入IUCN受威脅物種紅皮書名單中. This species has not been found after an extensive search at the type locality and other associated areas during 2013. It is at least in a very precarious condition, and probably extinct.
