| Distribution | N Ecuador (elevation 8500-9000 feet = 2390–3300 m)
Type locality: Ecuador
|
| Reproduction | oviparous |
| Types | Holotype: BMNH 1946.8.31.32 |
| Diagnosis | Diagnosis (genus Riama): Riama differs from members of Alopoglossinae by having its tongue covered in imbricate, scale-like papillae instead of oblique plicae (Harris, 1994), from Gymnophthalminae by having moveable eyelids, from Rhachisaurinae by having external ear openings, and from Ecpelopinae by lacking prefrontal scales. Within Cercosaurinae (sensu Castoe et al., 2004), Riama differs from all genera except Pholidobolus, Proctoporus, and Petracola by lacking prefrontal scales. It differs from Proctoporus by having a divided palpebral disc, from Pholidobolus by lacking two medial rows of widened gulars, and from Petracola by lacking the combination of smooth dorsal scales and femoral pores per hind limb in both sexes less than six (exclusive of preanal pores). After DOAN & CASTOE 2005.
