The historical range of this species was the Valley of Mexico at Xochimilco, and probably Chalco, and maybe in the eastern state of Mexico, central Mexico.
Habitat and Ecology
It inhabited wetland areas in the surroundings of southern Mexico City.
This species is most likely extinct, and has not been seen since it was first described in 1985.
The rapid and intense growth of Mexico City with its high rate of urbanization has caused the disappearance of the only known suitable habitats for this species.
It seems that no individuals of this species survive in the wild, but an intensive survey is needed to check all the possible localities where this species could occur. The Mexican government has placed this species in the "Endangered" category.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because its Extent of Occurrence is less than 100 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat around Mexico City.
