    Taxonomy from Smith 2009.

    Diagnosis from Smith 2005, p. 222: "Differs from G. longicaudus Kuhn, 1944 in lacking a strong ventral expansion of the coronoid and in having a clavicle whose ventromedial expansion is most extensive at the level of the clavicular fenestra rather than dorsolateral to it. Differs from G. grisolli Augé, 2005 in having a broader nasal spine of the premaxilla and a weaker and more rounded subdental shelf anteriorly on the dentary. Differs from G. lamandini (Filhol, 1877) in having a more restricted Meckelian groove, a more delicate anteromedial process of the coronoid, and distinct anterolateral and posterolateral processes of the coronoid."

    Identified by Dr. Krister Smith, Senckenberg Research Institute.

    Lost it playing cards...


    Sorry, I couldn't help myself. :D


    It seems to be very common that G. maarius. is found without a tail. Maybe he could drop it. According to Krister Smith, about half of the lizards found no longer have a complete tail.
