( Prata et al. 2017): Disc rounded to pentagonal, covered by medium size scales, imbricated, more numerous in the centre and in the inter-radial surface. Small rough-tipped spines scattered over the disc, more numerous at the edges. Radial shield large and triangular, occupying more than half the disc. They are united distally and separated by two scales proximally, the most internal more elongated. Ventral surface of the disc covered by small and imbricated scales. Bursal slits large. Oral shield sub-diamond-shaped. Adoral shield longer than wide, wider distally, separated proximally. Two oral papillae flattened and robust, similar in size. An apical papilla large and triangular. Six arms, about five times the diameter of the disc, tapering distally (Fig. 11 f).
