A new species of titi monkey, genus Callicebus Thomas, 1903, is described based on four individuals, one from a small tributary of the left bank of Rio Teles Pires, northern state of Mato Grosso, and three others from Largo do Souza, Rio Iriri, Pará, Brazil. The new species belongs to the Callicebus moloch species group, and the main diagnostic characteristics of the new species are the whitish forehead, sideburns and beard coloration, which are contiguous, forming a frame around the blackish face; overall body pelage coloration is pale grayish-brown agouti; hands, feet and tip of the tail whitish; belly and inner sides of fore and hind limbs uniformly orange. The pattern of pelage coloration and qualitative and quantitative skull morphology are described... |

Mustelids (Mustelidae) exhibit a wide morphological and ecological diversity, ranging from aquatic to semi arboreal and fossorial forms. It is the most diversity family in Carnivora, and this has promoted a great number of taxonomic arrangements for subfamilies, which can range from two to 15 depending on the author. The relatively recent use of molecular data has helped to elucidate the classification of mustelids, and eight subfamilies are currently recognized: Mustelinae, Galictinae, Helictidinae, Martinae, Melinae, Mellivorinae, Taxidiinae and Lutrinae. However, some of these subfamilies have nomenclatural problems, not receiving the oldest available name. The subfamily that includes martens (Martes, Charronia and Pekania), tayra (Eira) and wolverine... |

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... |
