Thyanta perditor

Thyanta perditor (Fabricius, 1794) Distribution: United States: AZ, FL, TX (Stål 1872, Rider & Chapin 1992). (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.Published as part of Rider, David A. & Swanson, Daniel R., 2021, A distributional synopsis of the Pentatomidae (Heteroptera) north of Mexico, including new state and provincial records, pp. 1-69 in Zootaxa 5015 (1) on page 39, DOI: 10.11646/zootaxa.5015.1.1, http://zenodo.org/record/515908
