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

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

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

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]
Habitat

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

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

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

C. alfredschmidti is oviparous.[3]
Conservation status

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