First record of Panochthus Burmeister (Xenarthra; Cingulata; Glyptodontidae) in Peru

Abstract

Panochthus Burmeister is one of the most geographically widespread glypto- dontid genera in the Pleistocene of southern South America. Recent systematic revisions re- vealed the presence of seven species: P. intermedius Lydekker, P. subintermedius Castellanos, P. tuberculatus (Owen), P. frenzelianus Ameghino, P. greslebini Castellanos, P. jaguaribensis Moreira and P. hipsilis Zurita, Zamorano, Scillato-Yané, Fidel, Iriondo and Gillette. An osteo- derm from Pleistocene deposits cropping out on the banks of the Desaguadero River, Peru, at about 3800 meters above sea level, is described herein. The presence of a clear reticular pattern on the outer surface of the osteoderm is indicative of Panochthus . This is the first record of Panochthus from Peru and, thus, the geographic range of the genus is extended.
