Authors: Arnaud Badiane, Pau Carazo & Enrique Font

Abstract: The blue-throated keeled lizard, Algyroides nigropunctatus, is distributed along the Adriatic coast from Italy to Greece
and is sexually dichromatic. Males display a striking blue on their throat, an orange ventrum, and a dark brown dorsal colouration, but their colouration has never been objectively assessed. Here, we describe the colouration of 13 male blue-throated keeled lizards from Cres Island (Croatia) using spectrophotometry and ultraviolet (UV) photography, and show that the blue throat and the blue spots located on the flanks reflect in the UV part of the spectrum. We discuss the potential role of UV-blue colouration in social signalling.
