Observations:
In a recent study of
Phymaturus
lizards,
Lobo & Quinteros (2005b)
described the new taxon
Phymaturus dorsimaculatus
from Copahue, Ñorquin (
37°49’S
,
71°06’W
), in the
Neuquen Province
,
Argentina
. The diagnostic traits and the phylogenetic evidence detailed by these authors provided powerful support to the hypothesis that this
Phymaturus
population differs from any of the remaining species included in their work (
i.e.
15 of the 17 species known until then; see above). However,
Lobo & Quinteros (2005b)
did not discuss the relationships between the new lizard,
P. dorsimaculatus
, and the recently described species
Phymaturus vociferator
from boreal Patagonia of
Chile
(
Pincheira-Donoso 2004a
). An analysis conducted on the original descriptions of both
Phymaturus
species
(
Pincheira-Donoso 2004a
;
Lobo & Quinteros 2005b
), as well as on living samples collected in Laguna del Laja (
type
locality of
P. vociferator
) and Copahue (
type
locality of
P. dorsimaculatus
), suggested that they might be conspecific. Indeed, the morphological and chromatical traits provided as diagnostic traits for both
P. dorsimaculatus
and
P.vociferator
exhibit strong overlap, even when comparing patterns of population variation (
e.g.
body size, scale countings, precloacal pores, coloration in males and females, and patterns of sexual dimorphism and dichromatism; see
e.g.
Figs. 1
and
2
in
Pincheira-Donoso 2004a
, and
Fig. 1a and 1b
in
Lobo and Quinteros 2005b
; see also description of diagnostic traits and variation).
Furthermore, the
type
localities of
P. dorsimaculatus
and
P. vociferator
are closely situated into the same area recently recognized as a zone of lizard endemism in the boreal Patagonia of Argentinean and Chilean borders, between
36°50’S
–
37°53’S
, and
70°35’W
–
71°30’W
(
Pincheira-Donoso
et al.
2007a
). Consequently, the available evidence cannot support the status of
P. dorsimaculatus
as a taxon different from
P. vociferator
, which we consider to be conspecific. Since
P. vociferator
was proposed before, on the basis of an official
type
series and locality (Museo Nacional de Historia Natural de
Chile
,
Pincheira-Donoso 2004a
),
P. dorsimaculatus
is herein considered a synonym of this species. It additionally means that
P. vociferator
would not be endemic to
Chile
, but would also occur in the northwestern Patagonia of
Argentina
.
In a previous work,
Scolaro (2006)
had already suggested that
P. dorsimaculatus
might be closely related to
P. vociferator
.
