Amended diagnosis by Taverne and Capasso 2012, p. 30 (translated from French by oilshale): “Pycnodontine which can reach several tens of centimeters. Moderately high body. Dorsal apex located in front of the origin of the dorsal fin. Ventral apex located at the level of the origin of the anal fin. Triangular cephalic profile and pointed snout. Cranial dermal bones decorated with microgranulations and wrinkles. Endocranium exposed behind the dermocranium. Frontal with a narrow posteroventral branch descending to the dermosphenotic and dermopterotic and having only limited contact with these two bones. Parietal narrow, elevated, surmounting dermosphenotic and lined with a posterior brush-like process.…”
