Distribution

This species is endemic to Cuatro Ciénegas valley, in Chihuahuan Desert, Mexico.^[2]

Ecology

Mexipyrgus carranzae is generally found only in soft sediment.^[4]

Water lily Nymphaea ampla is the most common aquatic macrophyte in abundance in its habitats.^[4] According to the isotope analysis by Chaves-Campos et al. (2012)^[4] it is probable that Mexipyrgus churinceanus feed on water lily Nymphaea ampla organic matter metabolized by sediment bacteria.^[4]

Predators of Mexithauma quadripaludium include the specialized snail-eating (molluscivorous) cichlid fish Herichthys minckleyi.^[2]
