Resumo: | Phylogenetic relationships within the liolaemid lizard genus Phymaturus were studied using parsimony analysis of morphological data. The data set includes 133 characters: 28 described in the literature as apomorphies of the three genera of Liolaemidae (Ctenoblepharys, Liolaemus, and Phymaturus), 21 published characters of allozymes and karyology, 53 characters taken from external morphology across all terminals of Phymaturus, and 31 from the skeletal anatomy. This data set includes representatives of 10 of the 12 species currently recognized in the literature plus twelve other terminals considered in this study and representing independent lineages assigned to patagonicus or palluma. Four of these terminals are described in the present study as new species, one belonging to the palluma group and the other three to the patagonicus group. We performed four analyses using different methods of coding binary polymorphic characters, and a new method for treating continuous characters. The traditional division of the genus in two groups is not supported here, with the patagonicus group resulting paraphyletic in some of the analyses. The palluma group is monophyletic and supported by many characters. A majority rule consensus tree of all runs recovers a reasonably well-resolved topology of the group. All analyses recovered a northern subclade within the palluma group, formed by species distributed in Argentina from northern of San Juan province (north to 30 degrees of latitude). In this analysis palluma from El Planchón (Chile) was found to be more closely related to this northern subclade than any other "palluma" form. |

Estudaram-se as relações dentro do gênero Phymaturus da familia Liolaemidae, usando análise de parsimônia de uma matriz formada principalmente por dados morfológicos. A matriz inclui 133 caracteres: 28 descritos na literatura como apomorfias dos três gêneros de Liolaemidae (Ctenoblepharys, Liolaemus e Phymaturus), 21 caracteres de alozimas e cariologia, 53 caracteres de morfologia externa e 31 do esqueleto, de todos os terminais de Phymaturus. A matriz inclui representantes de dez das doze espécies reconhecidas na literatura, e outros 12 terminais que neste estudo se consideram linhagens independentes e identificadas como P. patagonicus ou P. palluma na literatura prévia e nas coleções. Quatro destes terminais são descritos neste trabalho como espécies novas, uma pertencente ao grupo de P. palluma e outras três ao grupo de P. patagonicus. Realizaram-se quatro análises usando quatro métodos diferentes para codificar binariamente caracteres polimórficos, e um novo método para codificar os caracteres contínuos. A divisão tradicional do gênero em dois grupos não é apoiada pelo presente estudo, o grupo de P. patagonicus é parafilético em parte da análise. O grupo de P. palluma é monofilético e se sustenta por vários caracteres, as árvores de consenso por maioria, de todas as análises, mostraram com exceção de um par de politomías, uma topologia do grupo bem resolvida. Dentro do grupo de P. palluma, encontra-se um subclado formado por espécies distribuídas no norte da Argentina desde o norte da província de San Juan (ao norte dos 30° de latitude). Nesta análise, o P. palluma de El Planchón (Chile), relaciona-se mais com este subclado do norte que com qualquer outra forma de "P. palluma".
