Original diagnose after Koot et al. (2013) p. 316 [18013]: Triangular labial peg always present, sometimes flanked by two accessory nodes, and lingual peg less developed but always present. Acute longitudinal crest and horizontal rim present at crown shoulder, most pronounced lingually. Base slightly dejected lingually. Anaulacorhize vascularization consisting of few large foramina with labially a single row of small foramina near the crown–base junction.
