CommentArthrosaura synaptolepis differs from all other Arthrosaura in lacking prefrontal scales and in having two (vs. three) pairs of genials.

Distribution: although the species has been found near the border to Brazil, there are technically no reports from Brazil itself, hence COSTA & BERNILS 2015 do not list this species for Brazil. 
Etymologyfrom the Greek synaptos = joined together, and lepis = scale, referring to the apparent fusions that gave rise to the reduced number of head plates in this species.
