最初描述为 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 未被国际自然保护联盟(IUCN)在濒危物种红色名录中为自然保育进行评估. 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.
