Procambarus digueti is a species of fresh water crayfish in the genus Procambarus and in the family Cambaridae. It is endemic to tropical regions in the Pacific Coast of Mexico. It lives in shallow lakes where oxygen is plentiful and are the only decapod species in Mexico to live in waters 1,800 meters above sea level. P. digueti is believed to be one of the oldest species of Mexican crayfish due to its unusually low genetic variability between organisms and geographical evidence. It has experienced a greater amount of habitat loss than other crayfish species have in Mexico, leading to a decline in its populations and the IUCN Red List to deem it as an endangered species.

Procambarus lucifugus lucifugus, known as the Withlocoochee light-fleeing cave crayfish, is one of two subspecies of the vampire crayfish, along with Procambarus lucifugus alachua. It is distinct from P. l. alachua due its lack of eyespots. Intergrades of the two P. lucifugus subspecies, P. l. alachua as well as P. erythrops and P. leitheuseri have been found to have little genetic differentiation, especially when compared to P. l. lucifugus which is distinct from all of those. It has been suggested that P. l. lucifugus may prove to be a different species, found only in two freshwater caves, the location of one of which is unknown.
