Baroniinae
Baronia
Species of butterfly
Baronia brevicornis, commonly known as the short-horned baronia, is a species of butterfly in the monotypic genus Baronia and is placed in a subfamily of its own, the Baroniinae, a sister group of the remainder of the swallowtail butterflies.[2] It is endemic to a very small area of Mexico, where the distribution is patchy and restricted.[3][4]
The genus is named after Oscar Theodor Baron who collected the first specimen in the Sierra Madre region of Mexico.[5] The species was then described by Salvin.[6]
Morphological characteristics include an abdominal scent organ in females.[7][8]
Baronia is unique among swallowtail butterflies or their relatives in having an Acacia species, Vachellia campeachiana (synonym Acacia cochliacantha, family Leguminosae) as its larval food plant.[9][10]
