The genus Ptychoglossus is included in the family Gymnophthalmidae and
currently comprises 15 species distributed principally in western Amazonia.
Ptychoglossus brevifrontalis, initially thought to have a peripheral distribution in
Amazonia, was recorded in recent years in several localities in the interior of the
Amazon, indicating a wide distribution within the region. However, little information
on the morphological variation along the species range is available. In this report intraand
interpopulational variation in the morphology of Ptychoglossus brevifrontalis was
studied, including data on sexual dimorphism and ontogenetic variation. Ptychoglossus
nicefori was included in the study, due to its resemblance to P. brevifrontalis and a
history of synonymy between the two species. Geographic variation in some characters
was found, without however justifying the recognition of additional taxa. The validity
of P. nicefori is questionable but additional studies are needed before changes to the
taxonomy of the group are proposed. |
