A cast of the skull is deposited at the MGPV.

TYPE HORIZON AND AGE. — Top of the red pelitic beds of the M1 Member, Grès Rouge Group of the Rodez Basin, “Saxo-Thuringian”, upper Sakmarian to lower Lopingian ( Lopez et al. 2005, 2008), middle Early-early Late Permian.

EMENDED DIAGNOSIS. — A small caseid with the following autapomorphies: an unusually broad skull, large temporal fenestra, and lack of expansion of the axial neural spine. In addition, it can be distinguished from other caseids by presence of an supernumerary blade-like intranarial bone located posteromedially to the septomaxilla, proportional differences in forelimb and manus, presence of an accessory proximal articulation between metacarpals 3 and 4, medial recurvature of metacarpal, and its manual phalangeal formula of 2-3-4-4-3.
