The coastal tapeti (Sylvilagus tapetillus), also known as the Rio de Janeiro dwarf cottontail or dwarf tapeti, is a species of cottontail rabbit native to Brazil. Known from only three specimens, captured in the late nineteenth century in the Paraíba Valley, it was for a long time considered to be a subspecies of the common tapeti (Sylvilagus brasiliensis). Slightly smaller than its close relative, analysis in 2017 confirmed that it is sufficiently distinct in both appearance and genetics to be considered a species in its own right.[1] Due to destruction of its putative habitat in the densely populated Paraíba Valley, it is unclear whether or not the species still survives in the present day.
