Four groups of long and strongly curved spines along the trunk (ta–td) (fig. 5B), with blade-like structure and ventral insertion ending in a pointed apex (figs. 5B, E, 6A, C, E), but only the posteriormost saltatorial group (td) is barbed (fig. 5E). Four pairs of spines are inserted dorso-laterally (ta1–3, tb1), and five pairs are ventrolateral (tb1, tb2, tc2 and td) (fig. 5B). Saltatorial spines (td) intersect with each other posteriorly to spines tb2 and tc2 (figs. 5A, B, E, 6A) (fig. 5B). The dorsal posterior portion of the trunk is covered by smooth scales with different sizes, and without overlapping.

Each “protonephridium” extends for a large portion of the body (U53 to U77), with meandering loops (fig. 5C, D), covering 12 µm maximum width (fortunately the animal’s body was not compressed by coverslip, as frequently occurs in soft-bodied invertebrates). It is important to note that we could not perform ultrastructure studies, such as transmission electron microscopy, because the organism was lost during the light microscopy study; so we inferred protonephridium and canal cells according to comparisons of other studies with light photomicrographs of these structures supported by TEM analyses (e.g.
