Resumo: | The Geoffroy's cat Leopardus geoffroyi (d'Orbigny & Gervais, 1844) is a small cat found in the Southern Cone of South America and, depending on the author, four or five subspecies have been usually recognized (L. g. geoffroyi, L. g. paraguae, L. g. euxanthus, L. g. salinarum and L. g. leucobaptus), mainly based on external morphological characters, such as color pattern of the pelage. In order to clarify the taxonomy of L. geoffroyi, I analyzed approximately 200 specimens housed in museums. I have examined the external and craniodental morphology in quantitative and qualitative terms in the search for patterns of congruent characters that would indicate the existence of taxonomic units. Twenty craniodental measurements were taken and tested by univariate and multivariate (MANOVA, PCA and DFA) procedures. In this study I detected a great variation in the morphological characters, and thus it was not possible to determine whether any of these were geographically consistent and could be used to determine any taxonomic unit. Based on this, I do not recognize any subspecific division for L. geoffroyi. Along its geographic range, a gradual and subtle change from one color pattern to the next along the latitude was detected, but the morphological characters that were used to define the putative subspecies were also detected in a same population. Furthermore, the present study is congruent with the results obtained by previous molecular data, suggesting that L. geoffroyi has a high level of genetic diversity with no geographic structure. This indicates the existence of a large panmictic population with no significant barriers to gene flow and, as a consequence, no subspecies should be recognized. |

On the morphological variation and taxonomy of the Geoffroy's cat Leopardus geoffroyi (d'Orbigny & Gervais, 1844) (Carnivora, Felidae) The Geoffroy's cat Leopardus geoffroyi (d'Orbigny & Gervais, 1844) is a small cat found in the Southern Cone of South America and, depending on the author, four or five subspecies have been usually recognized (L. g. geoffroyi, L. g. paraguae, L. g. euxanthus, L. g. salinarum and L. g. leucobaptus), mainly based on external morphological characters, such as color pattern of the pelage. In order to clarify the taxonomy of L. geoffroyi, I analyzed approximately 200 specimens housed in museums. I have examined the external and craniodental morphology in quantitative and qualitative terms in the search for patterns of congruent characters that would indicate the existence of taxonomic units. Twenty craniodental measurements were taken and tested by univariate and multivariate (MANOVA, PCA and DFA) procedures. In this study I detected a great variation in the morphological characters, and thus it was not possible to determine whether any of these were geographically consistent and could be used to determine any taxonomic unit.

Along its geographic range, a gradual and subtle change from one color pattern to the next along the latitude was detected, but the morphological characters that were used to define the putative subspecies were also detected in a same population. Furthermore, the present study is congruent with the results obtained by previous molecular data, suggesting that L. geoffroyi has a high level of genetic diversity with no geographic structure. This indicates the existence of a large panmictic population with no significant barriers to gene flow and, as a consequence, no subspecies should be recognized. O gato-do-mato-grande Leopardus geoffroyi (d'Orbigny & Gervais, 1844) é um felídeo de pequeno porte encontrado no cone sul da América do Sul e, dependendo do autor, quatro ou cinco subespécies são habitualmente reconhecidas (L. g. geoffroyi, L. g. paraguae, L. g. euxanthus, L. g. salinarum e L. g. leucobaptus), principalmente baseadas em caracteres morfológicos externos, como o padrão de coloração da pelagem. Com a finalidade de esclarecer a taxonomia de L. geoffroyi, analisei aproximadamente 200 espécimes depositados em museus. Examinei a morfologia externa e craniodentária quantitativa e qualitativamente, procurando por padrões de caracteres congruentes que poderiam indicar a existência de unidades taxonômicas. Vinte medidas craniodentárias foram aferidas e posteriormente testadas através de procedimentos univariados e multivariados (MANOVA, PCA e DFA). Neste estudo detectei uma variação grande nos caracteres morfológicos, e com isso não foi possível determinar se alguns deles foram geograficamente consistentes e se poderiam ser utilizados para determinar alguma unidade taxonômica. Baseando-me nisso, não reconheço quaisquer divisões subespecíficas para L. geoffroyi. Ao longo de sua distribuição geográfica, uma mudança gradual e sutil de um padrão de coloração para outro foi detectada ao longo da latitude, porém os caracteres morfológicos que foram utilizados para definir as supostas subespécies foram detectados em uma mesma população. Além disso, o presente estudo é congruente com os resultados obtidos anteriormente através de dados moleculares, que sugeriram que L. geoffroyi tem um nível elevado de diversidade genética sem estruturação geográfica. Isto indica a existência de uma grande população panmítica sem barreiras significativas para o fluxo gênico e, como conseqüência, nenhuma subespécie poderia ser reconhecida.
