Red-brown Butterfly (Mormon)

Good luck! Try looking for a good Central American butterfly guide that shows upper and lower sides of male and female of each species. Butterflies of Central America. Volume 1. Kim Garwood & Richard Lehman. 2011. Eye Scry Publishing, McAllen, Texas. 304 pp. [Covers Oaxaca, MX through Panama, includes Papilionidae, Pieridae & Nymphalidae, almost 2,300 photos (provided by almost 70 different photographers) across 284 color plates, includes many, many subspecies, with range maps and principal photographic locations, index and quick index.] I have not yet seen this guide so maybe take a look at it before purchasing to make sure it has what you want. Good luck!

There are a few genera of tail-less swallowtails in Central America, but I'm not overly familiar with many of the individual species. Many of these butterflies have a body and wing style incredibly similar to your specimen. Family: Papilionidae Genus Battus has about 15 species in Central America with an incredible similar body and wing shape to your butterfly. Their larval hosts are pipevines (Aristolochia) More info: http://en.wikipedia.org/wiki/Battus_%28butterfly%29 Genus Parides has some 50 species in Central America. Some are tailless and many are sexually dimorphic which makes for a tricky ID. Their larval hosts are pipevines (Aristolochia) More info: http://en.wikipedia.org/wiki/Parides Genus Mimoides has about a dozen species local to Central America. Their larval hosts are members of the Pawpaw family (Annona) More info: http://en.wikipedia.org/wiki/Mimoides
