|Distribution||N Ecuador (elevation 8500-9000 feet = 2390–3300 m)|
Type locality: Ecuador
|Types||Holotype: BMNH 19220.127.116.11|
|Diagnosis||Diagnosis of the genus Riama: Riama differs from members of Alopoglos-sinae 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.|

Type Species: Riama unicolor GRAY 1858 is the type species of the genus Riama GRAY 1858.
Definition of the genus Riama: Tongue with imbricate, scalelike papillae. Head scales smooth without striations or rugosities: single frontonasal, frontal, and interparietal; paired frontoparietals and parietals; prefrontals absent; nostril pierced in a single nasal; nasals not in contact. Eyelids developed, lower with a translucent disc divided into several scales. Posterior gulars squarish. Limbs pentadactyl; digits clawed. Dorsal scales quadrangular or hexagonal, elongate, smooth, striate, rugose, or keeled, juxtaposed, forming transverse series only. Ventrals large, smooth, quadrangular, juxtaposed, forming regular longitudinal and transverse series. Femoral pores usually present in males and females; preanal pores present or absent in males or females. Tail cylindrical. After DOAN & CASTOE 2005.
|Etymology||The specific epithet, unicolor, is an adjective from the Latin that probably refers to the nearly unicolored dorsal and ventral color patterns of the holotype.|
