Cone-shaped head, slightly narrower than the trunk, with a pair of cephalic tentacles projected anterolaterally, 14 μm long, 2 μm thick basally, and 2.6 μm distally (fig. 7A). Terminal mouth ring, 5 μm long and 8 μm wide (fig. 7A). Pharynx is 28 μm long, with two bulbs separated by two weak constrictions, the posterior one much stronger than the other (fig. 7B).

reported rhomboid pedunculated scales that extend from dorsal head to posterior trunk on specimens from Corumbá. In contrast to this, the armature of specimens from Belém consists of partially pedunculated and spined scales, with the dorsal head covered by pedunculated rhomboid scales, followed posteriorly by simple spined scales with concave posterior end.
