Description
Original diagnosis after Frey, Coates, Ginter, Hairapetian, Rücklin, Jerjen & Klug, 2019 [28139]: Mandibular teeth with main cusps recurved lingually, of nearly identical length, each with two distinct striae forming sharp edges; lateral cusps with broader diameter than the median; two intermediate cusplets reach almost half central cusp length and thickness; tooth base squarish with rounded angles in aboral view: 5.2 mm wide and 4.5 mm long; base outline concave in labial, aboral, and lateral aspects; the basolabial projection wider than the median cusp and labiolingually narrow. Dorsal fin spines with gentle posterior curvature; basal opening extends to at least 50% of total height; insertion deep; ornament of fine ctenoid ridges.
