About Baronia brevicornis Salvin, 1893
Baronia brevicornis, commonly called the short-horned baronia, is a butterfly species. It is the only member of the monotypic genus Baronia, and is placed in its own subfamily, Baroniinae, which forms a sister group to all other swallowtail butterflies. This species is endemic to a very small, patchily distributed restricted area of Mexico. The genus Baronia is named for Oscar Theodor Baron, who collected the first specimen in the Sierra Madre region of Mexico; the species was later described by Salvin in 1893. A morphological feature of this species is that females possess an abdominal scent organ. Baronia is unique among swallowtail butterflies and their relatives because its larvae feed on Vachellia campeachiana (synonym: Acacia cochliacantha, family Leguminosae), a species related to acacias.
