Taxonomy according Fossilworks.org. Diagnosis for Moythomasia nitida in Choo 2015, p. e952817-5: "A Moythomasia with a standard length of up to 15 cm, with about 55 vertical scale rows from head to caudal peduncle. Frontal margins form a straight contact against the posterior margin of the rostral. Numerous pores on the ventral surfaces of the lower jaw, opercular-gular series, and pectoral girdle. Rostral with squared-off anteroventral margin that is excluded from the biting margin by the premaxillae. Posterolaterally directed ridges on the dorsal lamina of the rostral. Postorbital maxillary blade with gently curved dorsal margin. Suboperculum more than half the size of the operculum, with small squared-off anterodorsal margin against the adjoining accessory operculum. Two postorbitals anterior to preoperculum, excluding that bone from contact with the jugal. Ornamentation on anterior face of preoperculum dorsoventrally oriented. Dentary teeth of similar size to maxillary teeth. Mandibular sensory canal dorsally deflected on the anterior half of the dentary. Dorsal and anal fins positioned opposite to one another. Pectoral lepidotrichia evenly segmented to fin base. One pair of round, preanal scutes. Flank scales ornamented with anastomosing ridges with intermixed punctae."
