Declared a new species back in 2006

(Russel,Bergman Systematics and biogeography of the widespread Neotropical gekkonid genus Thecadactylus (Squamata), with the description of a new cryptic species Zoological Journal of the Linnean Society, 2007, 149, 339–370.)

The study shows a distinct genetic lineage of a once thought homogeneous species. The major distributional difference seems to be the new species are dominant in Amazonian headwaters of Peru, Ecuador and Colombia

Solimoes is what the Brazilians call the Amazon from Manaus upstream to Peruvian / Colombian headwaters)
