A new highland species of Arthrosaura Boulenger, 1885 (Squamata: Gymnophthalmidae) from Maringma tepui on the border of Guyana and Brazil

A new species of Arthrosaura (Squamata: Gymnophthalmidae) is described based on a female specimen obtained at 2112 m above sea level on Mount Maringma, a poorly known sandstone flat-topped table mountain (tepui) located in the eastern Pakaraima Mountains, at the Guyana-Brazil border. Arthrosaura hoogmoedi sp. nov. is mainly distinguished from its known congeners by the following combination of characters: four supraoculars, prefrontals in contact with loreals, lower eyelid opaque, 32-33 smooth temporal scales, middorsal scales distinctly narrower than adjacent dorsal scales, and a dark brown dorsum with a black middorsal stripe from nape to tail, and a tan ill-defined dorsolateral line from nape to midbody.
