A look at the Family Agamidae


Phuwua Rock Agama


M. phuwuanensis was originally assigned to Ptyctolaemus but was assigned its own genus due to (1) the presence of femoral pores, which distinguished it from all other genera of draconine agamids, and (2) the combination of femoral pores and haired skin sense organs distinguished it from all other agamid lizards.
