Research overview: cryptic species among the margay and oncilla

The small spotted cats of South and Central America, including the margay and the oncilla or little spotted cat, harbor cryptic genetic diversity that has reshaped their taxonomy. This overview surveys molecular studies that split the oncilla into separate northern and southern species, revealed deep mitochondrial lineages, and documented past hybridization with the pampas cat. It discusses the conservation consequences of recognizing additional species, the difficulty of distinguishing these similar-looking cats by appearance alone, and how genetic analysis of the ocelot lineage has repeatedly uncovered hidden diversity, underscoring how much felid biodiversity remained unrecognized until molecular tools were applied.
