Diagnosis
ReferenceDiagnosis
A. Pérez-García 2017It differs from the other members of Bothremydini by the following character combination: very shallow nuchal notch; wider than long nuchal plate; five (exclusive to this taxon), six or seven neurals; first vertebral on the first pair of peripherals or reaching the second; each scute of the first pair of marginals much wider than long; overlap of the first pair of marginals on no more than half of the nuchal anterolateral margin; medial contact of the humerals; absence of overlap of the pectorals on the epiplastra; overlap of the pectorals on the entoplastron; pectoro-abdominal sulci crossing the mesoplastra; laterally positioned orbits; well-developed posterior projection of each squamosal; supraoccipital-quadrate contact; maxilla-quadrate contact; presence of a pit on each triturating surface; very wide posterior triturating surfaces; rounded lateral edges of the maxillae; no accessory ridges on the triturating surfaces; large exposure of the jugals on the triturating surfaces; triangular basisphenoid in ventral view; prootics not exposed in ventral view; relatively shallow fossa pterygoidea.
