Abronia bogerti

Abronia bogerti, known by the common name Bogert's arboreal alligator lizard, is a species of lizard in the family Anguidae. The species is endemic to Mexico.
Etymology.
The specific name, "bogerti", is in honor of American herpetologist Charles Mitchill Bogert.
Geographic range.
A single specimen was collected in 1954, and "A. bogerti" has not been spotted since. The location was "north of Niltepec, between Cerro Atravesado and Sierra Madre, Oaxaca", in Mexico.
Conservation status.
Because the species "A. bogerti" was collected in the canopy of the forest, it is believed that deforestation and ongoing crop and livestock farming pose the largest threats to its survival. Mexican law protects the lizard.
