The genus Spilogale includes all skunks commonly known as spotted skunks and is composed of four different species: S. gracilis, S. putorius, S. pygmaea, S. angustifrons. Mammalogists consider S. gracilis and S. putorius different species because of differences in reproductive patterns, reproductive morphology, and chromosomal variation. However, interbreeding has never been falsified. The name Spilogale comes from the Greek word spilo, which means "spotted", and gale, which means "weasel". Putorius is the Latin word for "fetid odor". Gracilis is the Latin word for "slender".
