Comment | Subspecies: Marcuzzi (1950) examined specimens from Bobare, Lara, and El Pilar, Sucre and questioned the status of the subspecies T. b. kugleri, arguing that colour variation in a species, which appears to be highly variable in this case, is not recommended in the recognition of subspecies. RIVAS et al. 2012 agree with and follow Marcuzzi in not recognizing T. bifasciatus kugleri as a valid taxon. Type species: Tretioscincus castanicerus COPE 1862 is the type species of the genus Tretioscincus COPE 1862. Distribution: Cole et al. 2013 do not believe that this species occurs in Guyana despite the existence of one published report (Beebe 1945:23) and one AMNH specimen (R-137364), both of which are probably in error. |
Etymology | Named after Latin bifasciatus with two bands, strips; ribbons. [“...de chaque côté du dos, depuis l'extrémité du museau jusq'à l'origine de la queue, une ligne jaune..."]. (from Esteban Lavilla, pers. comm., May 2024) The genus was named after Greek tretos (τρητός), perforated, with a hole in it + Latin Scincus, lizard genus due to Laurenti, 1768 (see). ["...The discovery of this little lizard is particularly interesting, as exhibiting femoral pores for the first time among the Scincidae..."]. |
