Original description as Notropis grandis:
- Domínguez Domínguez, Omar & Rodolfo Pérez-Rodríguez, Luis Escalera-Vázquez, Ignacio Doadrio. 2009. "Two new species of the genus Notropis Rafinesque, 1817 (Actinopterygii, Cyprinidae) from the Lerma River Basin in Central Mexico". Hydrobiologia. v. 19(n. 2), pp. 159-172 (ffm00933) (abstract)
Conservation: Notropis grandis is evaluated by the international union for the conservation of nature in the iucn red list of threatened species as (EN) endangered (2019). The introduction of the exotic carp species Cyprinus carpio and Ctenopharyngodon idella and their parasite Bothriocephalus acheilognathi seems to have had a negative impact on Notropis grandis. Indeed, the repercussions of introducing carp species and their parasites on native fish species and their habitats in Mexico have been well documented (from Domínguez Domínguez et al., 2009:167).
