Coordinator notes: I concur with your suggested ID...I viewed the photos enlarged and it looked like there was a costal-fold on the edge of the forewing in the top photo...indeterminable on the one more head on. The hyaline spots are also not as well developed but not unlike some T. mexicana nevada (=dobra) in my collection but matches more pylades than them. Usually smaller is mexicana...and I cannot gauge size from the photos. The best way to separate the two is by the costal-fold...mexicana males do not have this structure on the forewings but often they can be also told apart by have more hyaline spots on the forewings...but not always!
