**1. Introduction**

*Liolaemus* species of the *L. montanus* group comprise about 60 species and several candidate species [1–3]. The geographic distribution of this group ranges from central Per ú and Bolivia to northern Argentina and Chile, and from sea level to more than five thousand m.a.s.l. Thirteen species in the northern range of this group are known in Per ú: *L. annectens*, *L. aymararum*, *L. etheridgei*, *L. evaristoi*, *L. insolitus*, *L. melanogaster*, *L. ortizi, L. poconchilensis*, *L. polystictus*, *L. robustus*, *L. signifer*, *L. thomasi,* and *L. williamsi* ([2,4] this paper). Recently, two candidate species ("Nazca" and "Abra Toccto") have been proposed based on an integrative approach in the northern range of the *L. montanus* group, but species description are still lacking [2].

Moreover, a more comprehensive phylogeny of the *Liolaemus montanus* group identified another well supported candidate species (*Liolaemus* "Moquegua") based on two mitochondrial and five nuclear markers. This candidate species forms a clade with *Liolaemus* "Nazca", *L. insolitus* and *L. poconchilensis* [3]. *Liolaemus poconchilensis* is one of these rare "toad-like" or "phrynosauroid" head lizards (eye diameter longer than snout-eye distance, poorly di fferentiated scale heads, short snout, short and triangular lower jaw), with eyes surrounded by enlarged ciliary scales or "combs" [5] *Liolaemus* "Moquegua" is similar in head shape to *L. poconchilensis*, but it lacks the "combs" surrounding the eyes and other traits we describe here. In this paper, we also describe two new species previously identified as *Liolaemus* "Abra Toccto" and *Liolaemus* "Nazca", and comment on conservation issues threating the new species and other Peruvian species of the *L. montanus* group.
