Original description as Xenotaenia resolanae:
- Turner, Clarence L. 1946. "A contribution to the taxonomy and zoogeography of the goodeid fishes". Occasional Papers of the Museum of Zoology, University of Michigan. (495):495 (ffm04518)
Conservation: Xenotaenia resolanae is evaluated by the international union for the conservation of nature in the iucn red list of threatened species as (VU) vulnerable (2018). Water pollution from sugar mill discharges, human sewage, and animal wastes had eliminated or reduced several populations by the 1980s, but since then the remaining populations seem to have stabilized (Lyons et al., 2019:144). An additional threat comes from nonnative fish species causing competition for food (Köck, 2019).
