| A. Pérez-García 2018 | Member of Bothremydini characterized by the following combination of characters: relatively large shell, exceeding 45 cm; elongated and elliptical carapace, its length being almost 1.4 times that of its width; slightly wider than long nuchal plate; seven neurals, the first five being notably longer than wide, especially the first, which is more than twice as long as wide; antero-lateral margins of the first vertebral scute reaching the second pair of peripherals; first vertebral as wide as the second; first to third vertebrals wider than long; overlap of the first pair of marginals on more than half of the nuchal anterolateral margins; outer surface of the carapace and plastral plates lacking a well-developed ornamental pattern; long plastral bridge, longer than the plastral lobes; broad plastral lobes (the anterior being more than twice as wide as it is long), with sub-straight lateral margins; trapezoidal anterior lobe; short and wide anal notch; posterior end of the entoplastron anterior to the plastral bridge level; longer than wide mesoplastra; medial contact of the humeral scutes; overlap of the anterior region of the pectorals on the epiplastra; long overlap of the pectorals on the entoplastron; pectorals not reaching the anterior margins of the mesoplastra. |
