Diagnosis
ReferenceDiagnosis
J. L. Benedetto 2013 (Tunaria)Convexiplane to strongly dorsibiconvex profile. Ventral interarea moderately high, strongly apsacline to catacline. Large subflabellate to flabellate ventral muscle field. Pedicle callist present. Cardinal process differentiated into a long shaft and a bulbous, bi- or trilobed myophore. Brachiophore bases long, subparallel, converging towards low notothyrial platform continuous with broad median ridge. Fulcral plates absent.
E. Villas et al. 2015Shell convexiplanar, rarely resupinate or strongly dorsibiconvex, with ventral median carina and dorsal sulcus, ventral interarea strongly apsacline to catacline, variably costellate with lateral ribs incurved postero- laterally to intersect posterior margin of valves, related to cardinal canals penetrating ventral interarea wall; ventral muscle field large with flabelliform diductor scars; brachiophore plates strongly convergent onto valve floor, with parallel bases continuous anteriorly from parallel ridges, excavated laterally by adductor scars; cardinal process bladelike with a pair of short lateral plates, subparallel to slightly converging posteriorly, on floor of apical part of notothyrial cavity.
