Hoplocercus spinosus (Fitzinger, 1843)

The Weapontail or Brazilian spiny-tailed lizard (Hoplocercus spinosus) is a lizard belonging to the monotypic genus Hoplocercus. It is found in the Cerrado and adjacent Cerrado–Amazon mosaics in Brazil and Bolivia. It is a quite distantly related of the other members of Hoplocercinae, as it is believed to have diverged from these about 35 million years ago.

As suggested by its name, it has a short, highly spiny tail (it is superficially similar to Uromastyx and the smaller species in Ctenosaura); when disturbed, it retreats to its burrow with the tail orientated towards the entrance. It is nocturnal, and feeds on arthropods.
