Bornean Horned Agama Harpesaurus borneensis (MERTENS, 1924)

You’ve probably never heard of the Bornean Horned Agama, Harpesaurus borneensis (MERTENS, 1924), it is quite possibly one of the rarest lizards in the world and only known from few specimens. The genus name comes from the greek harpe (=sickle) and saurus (=lizard), the males of this species possessing this distinctive “sickle” on their snout. Based on what we know it seems this species is the only live bearing agamid in whole south east asia.
