Author's Remarks: I have only observed this species alive three times in Louisiana. The first was a very large individual in 2011 sunning on a slope in Chicot State Park (Evangeline Parish). I found another dead on the road in 2012 in Kisatchie National Forest (Natchitoches Parish). In 2017 a group of us found two in one morning in West Feliciana Parish. And, in early 2018, a group of us found a large individual in New Orleans East.
