Description
Revised diagnosis after Bhat, Ray & Datta, 2017 [25804]: Lonchidiid hybodont characterized by elongated teeth with mesiodistal length greater than or equal to twice the apicobasal height, a high principal cusp, labial horizontal ridge situated near crown-root junction, lingual ridge high up on crown, linear depression or groove along the crown-root junction, small vertical cristae as crown ornamentation. Anterior teeth are broad, triangular and robust, have subdued and blunt principal cusp, a pair of incipient lateral cusplets, and low, hanging labial peg. Anterolateral teeth have high, pyramidal principal cusp with two or three small but pointed lateral cusplets, and triangular labial and lingual protuberances. Posterolateral teeth have four incipient lateral cusplets, prominent bilobed/rounded, hanging labial and small/incipient lingual protuberances
