Description
editLike all glyptodonts, this animal had a robust carapace, formed by osteoderms fused together, covering a large part of its body. Phlyctaenopyga was a medium-sized glyptodont, not exceeding two meters in length. Its carapace was made of osteoderms whose central figure was surrounded by two or three rows of peripheral figures ; the second row was complete only in a few osteoderms in Phlyctaenopyga ameghini, while the third row was always incomplete. The central figure of the osteoderms was convex and protruding, almost hemispherical. The skull was very short and broad, especially in the snout area. The osteoderms covering the head were practically devoid of ornamentation.
Classification
editThe genus Phlyctaenopyga was first described in 1944 by Cabrera, for a species of Late Miocene glyptodont first ascribed to the genus Plohophorus, P. ameghini. Cabrera also attributed the species Nopachthus trouessarti to this genus, as Phlyctaenopyga trouessarti. Those two species were mainly distinguished by details of their osteoderms.
Phlyctaenopyga was a glyptodont, a clade of cingulates related to the modern armadillos, with a rigid carapace. Phlyctaenopyga seems to have been close to the genera Nopachthus and Plohophorus, within the tribe Sclerocalyptini.
