Group
reichei
The species herein included in the group
reichei
have commonly been recognized as members of the controversial genus
Phrynosaura
(
Werner 1907
;
Donoso-Barros 1966a
, b,
1972
;
Núñez & Jaksic 1992
;
Núñez
et al.
2003
). Over the last century, many authors have suggested that clear patterns of differentiation in osteological and cytogenetical traits observed exclusively in
L. audituvelatus
,
L. erroneous
,
L. manueli
,
L. poconchilensis
,
L. reichei
and
L. torresi
would support the hypothesis that these species represent a discrete evolutionary line (
e.g.
Núñez
et al.
1998
,
2003
). Yet, on the other hand, some studies conclude that these traits may not be sufficient evidence to separate this still hypothetical group of species from the
Liolaemus
genus (
Frost & Etheridge 1989
;
Etheridge 1995
;
Etheridge & Espinoza 2000
;
Valladares 2004
). Recent molecular phylogenies have contributed to clarify in part this problem. This research reveals that at least the two “
Phrynosaura
” species analysed phylogenetically so far, are nested within
Liolaemus
(
Valladares
et al.
2002
;
Schulte
et al.
2004
). Therefore, these findings appear to support
Frost & Etheridge’s (1989)
and
Etheridge’s (1995)
proposal that
Phrynosaura
is a synonym of the genus
Liolaemus
. Nevertheless, it still remains unknown whether the currently six species assigned to
Phrynosaura
(or alternatively to the group
reichei
; see
Núñez
et al.
2003
;
Valladares 2004
) actually form a monophyletic clade within this genus (phylogenetic evidence suggest that these species are members of the series
signifer
; see above). Since the anatomical and cytogenetical evidence reported in previous papers suggests that these six species would be closely related taxa (
Núñez
et al.
2003
), we include them into the group
reichei
(
e.g.
Valladares 2004
). However, further phylogenetic studies are needed to test the validity of this classification criterion.
