Contents:

Endemism: 0%  100%
Remarks:
Validity of Thalesius is disputed.
The single species of this genus is sometimes placed in the genus
Xenodon under the name Xenodon werneri.
Although nested within (and thus synonymous with)
Xenodon (Zaher, Grazziotin, Cadle, Murphy, Moura-Leite & Bonatto 2009;
Pyron, Burbrink & Wiens 2013; Wallach, Williams & Boundy 2014),
it is retained herein as a separate genus, following Avila-Pires, Hoogmoed & Rocha (2010).

Xenodon werneri Eiselt [substitute name for Procteria viridis Werner 1924] (Ferreira-Yuki 1993) |
Remarks:
Peters & Orejas-Miranda (1970) did not treat this taxon as a valid species, although citing Eiselt's (1963) paper, in which the author recognized the taxon under
the name Xenodon werneri.
It was regarded as a separate species by Gasc & Rodrigues (1980) and Chippaux (1986), and later separated from the genus
Xenodon in the new genus Thalesius (under the revalidated species
name viridis).
Distribution:
Brazil
