Examined material. DZMB-HH-4795-07 (DZMB-Senckenberg Biozentrum Grindel und Zoologische Museum). Serial sections (nine slides) and sclerite preparations (one stub, five slides). Guinea Basin. DIVA2 Me 63/2 area 4, station 90 (000º 40.49’N, 005º 29.71’W), 5144 m depth GoogleMaps .
Description. Elongate body that is circular in cross-section (2.85 mm long, 0.2 mm wide in the middle and anterior region) with rounded anterior end and narrow posterior end (75 μm) with a slight digitiform projection (characteristic of Dondersia ). It is slightly yellowish in 70% ethanol ( Figure 8 B View FIGURE 8 ). It has leaf-shaped scales and solid acicular sclerites of three types: 1) Leaf-shaped scales ( Figure 8 View FIGURE 8 B-1) are the most abundant variety. With a rounded proximal end and smaller than the other scales (25.9 to 37.7 μm long, 10.2 to 15.5 μm wide in its middle part). 2) Solid straight acicular sclerites ( Figure 8 View FIGURE 8 B-3) with a rounded and wide proximal end. The base is between 2 and 3 μm wider than the middle region, which is in turn between 1 and 0.5 μm wider than the apex (66.5 to 167.6 μm long, 4.3 to 6.2 μm wide in the middle region). These sclerites are concentrated at the ventral posterior end of the animal. 3) Solid, curved acicular sclerites ( Figure 8 View FIGURE 8 B-2; 50 to 51 μm long, 5.7 to 6.5 μm wide).
