Alopoglossus brevifrontalis ( Boulenger, 1912 )


Alopoglossus brevifrontalis ( Boulenger, 1912)

Distribution: Widespread in the Amazonia of Brazil, Peru, Ecuador and Colombia ( Ribeiro-Júnior &Amaral 2017). In Colombia it is distributed throughout most of the Orinoquia and Amazonia regions ( Fig. 4A View FIGURE 4 ).

Similar species: This species is differentiated from all the other sympatric and similar species of Alopoglossus in the cis-Andean region due to the presence of occipital scales (absent in A. atriventris , A. avilapiresae , and A. buckleyi ); and for the presence of prefrontal scales (absent in A. bicolor ). In addition, Alopoglossus brevifrontalis may be confused with Arthrosaura reticulata given their external morphological resemblance. However, Al. brevifrontalis can be easily distinguished in having four supraocular scales (three in Ar. reticulata ); three pairs of chinshields (four in Ar. reticulata ); and mostly squared ventral scales in the medial rows (rectangular in Ar. reticulata ). For a more detailed description see Ávila-Pires (1995).

Remarks: Ptychoglossus nicefori was considered as a junior synonym of “ Ptychoglossus brevifrontalis ” (= A. brevifrontalis ) by Peloso & Ávila-Pires (2010), since they considered that the morphological differences between them were not enough to be different species.
