Leopardus
Leopardus is a genus comprising eight species of small cats native to the Americas. This genus is considered the oldest branch of a genetic lineage of small cats in the Americas whose common ancestor crossed the Bering land bridge from Asia to North America in the late Miocene.
Leopardus species have spotted fur, with ground colors ranging from pale buff, ochre, fulvous and tawny to light gray. Their small ears are rounded and white-spotted; their rhinarium is prominent and naked above, and their nostrils are widely separated. They have 36 chromosomes, whereas other felids have 38.
The generic name Leopardus was proposed by John Edward Gray in 1842, when he described two spotted cat skins from Central America and two from India in the collection of the Natural History Museum, London. Several genera were proposed in the 19th and early 20th centuries for small spotted cats in the Americas, including:
Analysis of skull morphology of these taxa revealed close similarities in their base of skulls and nasal bones, their masticatory muscles, and dentition. Phylogenetic analysis of tissue samples of these taxa and their ability to hybridise support the notion that they are members of the same genus. The following eight extant Leopardus species have commonly been recognized as valid taxa since 2017:
Additionally, more recent genetic analyses in 2017 and 2021 proposed the recognition of a third tigrina-like species, Leopardus emiliae.
A 2021 analysis of 142 pampas cat museum specimen collected across South America showed significant morphological differences between them. Therefore, it was proposed to split the historically-contentious pampas cat species complex into five species: Leopardus colocolo, Leopardus braccatus, Leopardus garleppi, Leopardus munoai, and Leopardus pajeros. Later that same year, it was noted that the oldest available name for pampas cats of the Uruguayan savannah region was Leopardus fasciatus, not L. munoai.
Another study in 2023 described another new species, Leopardus narinensis, based on a single dried skin collected in 1989 on the Galeras Volcano in the Nariño Department of Colombia. They found it to be very different from all other Leopardus species both morphologically and genetically.
A different study in 2024 did a detailed analysis of both the morphology and genetics of specimens assigned to Leopardus tigrinus, Leopardus guttulus, and Leopardus emiliae. It suggested L. t. pardinoides should be elevated to species status as Leopardus pardinoides due to significant differences in morphology, genetics, and ecology. The study also assigned the subspecies L. t. oncilla to be a subspecies of L. pardinoides as L. p. oncilla. Additionally, genetic analysis suggested that Leopardus emiliae was not genetically distinct from L. tigrinus, and thus may be invalid. The study recommended the common names savannah tiger-cat for L. tigrinus, Atlantic Forest tiger-cat for L. guttulus, and clouded tiger-cat for L. pardinoides.
