Stenocercus tricristatus

(no common name)

-

-

1851 Ophryessoides tricristatus Dumeril
Stenocercus tricristatus Frost 1992

Remarks: Previously included dumerilii. After dumerilii was resurrected from the synonymy of tricristatus (Avila-Pires 1995), the latter species is known only from a single specimen from Brazil (without precise locality data). The specimen most likely originates from Minas Gerais (Avila-Pires 1995; Torres-Carvajal 2007; Costa & Bérnils 2018). However, for unknown reasons, Schlüter, Icochea & Perez (2004) listed the species from Amazonian Peru. Records from Para, Brazil, (e.g., Cunha 1961, 1981) refer to dumerilii (Avila-Pires 1995).
