The Tenerife speckled lizard (Gallotia intermedia) is a recently discovered lacertid (wall lizard) endemic to Tenerife in the Canary Islands.[4] It is the smallest member of the clade containing the western islands' giant species.[6]

It was discovered in 1996 by biologist Efraín Hernández in the Macizo de Teno in the extreme northwest of Tenerife.[5] Although it is believed that the species was once widespread throughout much of the island, nowadays it is only known from a small area of coastline in the extreme west of the island, and also from Montana de Guaza in the extreme south.[2]

The total number of animals in the northwestern distribution area is 500 (estimated in 2008), in 40 isolated populations along altogether 9 km of coastline. In the south, there are about 100 animals. The main threat to this lizard is predation by feral cats and, to a lesser degree, by rats. The lizards are increasing in number since the turn of the century as a result of control of introduced mammals.[2]

Notes

  1. ↑ This species was first informally described in 1999 in a field guide, before being more formally described[4] in 2000 by Hernández and colleagues.[5] Whether the first description is valid remains in the grey zone of biological nomenclature.[4]
