This copepod is now considered to be Extinct. There have been numerous directed surveys (2007–2018) of the zooplankton of the small El Junco Lake following the impacts of introduced tilapia, and the species has not been recorded despite being formerly abundant.

This diaptomid copepod was only recorded from El Junco, a permanent freshwater crater lake in San Cristóbal island, Galápagos archipelago, Ecuador (Elías-Gutiérrez et al. 2023). El Junco crater lake is located at 675 m elevation; the lake is 270 m in diameter, with a surface area of 6 ha (Elías-Gutiérrez et al. 2023).

This copepod was abundant within its limited range until at least 2004; it was not encountered during subsequent directed surveys between 2007–2018 (Elías-Gutiérrez et al. 2023). The species was declared as extinct in 2020 (Elías-Gutiérrez et al. 2023).

This species was limited to a small permanent freshwater crater lake (El Junco), on San Cristóbal island, Galápagos archipelago (Elías-Gutiérrez et al. 2023) where it formed part of the zooplankton community.

This species has been declared extinct following illegally introduced fish (tilapia) predation (2005 introduction, since eradicated); rotenone treatment (principally to eradicate the tilapia); and other major disturbances (Elías-Gutiérrez et al. 2023).

There is no use or trade in this species.

El Junco Lake is managed by the Galapagos National Park Service. There have been many directed surveys for this species within its limited range, and despite its previous abundance, it was not recorded in plankton surveys between 2007 and 2018 (Elías-Gutiérrez et al. 2023). Although additional surveys are recommended, it seems highly likely that this species is now extinct.
