( Mexico , Central America, West Indies, South America). Comments: This species is characterized by having spinose humeral angles. There is also a form of Thyanta custator accerra (named spinosa by Ruckes 1957a ) that has the humeral angles more or less spinose. Prior to the work of Ruckes (1957a) , many workers referred to specimens with spinose humeral angles from the desert Southwest as this species. In truth, Rider & Chapin (1992) only listed two records of this species from the western United States : one from the very southern tip of Texas , and another in the southeastern corner of Arizona . All other records should be referred to Thyanta custator accerra .
