Callicorini Taxonomy
The Callicorini Tribe (Eighty-eights and Relatives) in the Subfamily Biblidinae (Tropical Brushfoots) in the Family Nymphalidae (Brush-footed Butterflies) is endemic to North and South America. We treat this tribe as having 9 visually distinctive genera. iNaturalist generally follows Warren, A. D., K. J. Davis, E. M. Stangeland, J. P. Pelham & N. V. Grishin. 2013. Illustrated Lists of American Butterflies for New World Butterfly taxonomy. But there are a few areas where the Illustrated Lists of American Butterflies is out of step with most other sources and complicates identification, so we're making a few exceptions.
Originally many of the genera in Callicorini were lumped in the genus "Catagramma". Illustrated Lists of American Butterflies seems to have only partially split this genus up. What they leave in "Catagramma" the Tree of Life Web Project and Markku Savela's Lepidoptera and Some Other Life distribute among Callicore and a monotypic Paulogramma. While these two genera are similar Learn About Butterflies has a good tip for distinguishing these genera (which I echoed here).
Tree of Life Web Project and Markku Savela's Lepidoptera and Some Other Life also differ from Illustrated Lists of American Butterflies by spliting off the monotypic Catacore kolyma from the rest of Diaethria. To me, Catacore looks midway between Diaethria and Callicore as you can see here.
The two Mesotaenia species have spots, the many Perisama species usually don't. When Perisama have spots, there are 5 rather than 6 as in Mesotaenia as described here.
This group is famous for the 'eighty-eights' based on the finely marked patterns on the hind-underwings that spell out 88. But the remaining genera: Orophila,Haematera, and Antigonis, don't have any finely marked patterns on their underwings. Pictures of the monotypic Antigonis can be found here
We are sticking with Illustrated Lists of American Butterflies in elevating Diaethria asteria to species status distinct from Diaethria astala, mainly because thats how its been on iNat and alot of people have observed both of these species.
Perisama is a diverse genus with lots of newly described species coming out. We're going with Markku Savela's Lepidoptera and Some Other Life because it includes alot of species not in these other sources. We're also including Perisama arhoda which isn't in any of these sources because its recognized by the Humboldt Institution as described here.
