The Campeche spiny-tailed iguana (Cachryx alfredschmidti)[1] is a species of lizards in the family Iguanidae. The species is found in southeastern Mexico and adjacent Guatemala.[3]


The specific name, alfredschmidti, is in honor of German herpetoculturist Alfred Schmidt.[3][4]


Adult males of C. alfredschmidti reach at least 170 mm (6.7 in) and females 152 mm (6.0 in) in snout–vent length.[2] Tail length varies from 74 %[5] to 85% of the snout–vent length.[2]

Geographic range[edit]

C. alfredschmidti was thought to be endemic to southern Campeche in Mexico.[1][2] However, in 2003, this species was also recorded by a scientific expedition to the Mirador-Río Azul National Park in the Petén Department in Northern Guatemala. This was the first record in Guatemala's herpetofauna for this species.[5]


The natural habitat of C. alfredschmidti is tropical moist lowland forest[1] and seasonally flooded scrub forest.[5]


C. alfredschmidti is arboreal.[1] It can find safety in hollow branches and tree trunks, blocking the entrance with its spiny tail.[2][5]


Fecal samples suggests that the diet of C. alfredschmidti consists of leaves, though it probably will eat arthropods too.[2]

Conservation status[edit]

C. alfredschmidti is potentially threatened by habitat loss and degradation.[1] The Guatemalan population was found in the Mirador-Río Azul National Park.[5]
