( Fig. 5 View FIGURE 5 A–C)

Eusyllis nuchalata Hartmann-Schröder, 1965: 115 View in CoL –118 Figs. 76–79.

Material examined. ZMUH P- 14586, three fragmented, incomplete paratypes.

Re-description. Body fragile, all specimens fragmented. Prostomium ovate, wider than long. Palps large and relatively short, triangular, separated at basis, ventrally folded. Nuchal organs semicircular, extending laterally over prostomium. Tentacular segment semicircular, shorter than subsequent segments, dorsally covering posterior part of prostomium. Antennae, tentacular cirri and dorsal cirri filiform, very slightly and indistinctly articulated on anterior part of body, smooth and short from midbody ( Fig. 5 View FIGURE 5 A). Cirrophores well developed ( Fig. 5 View FIGURE 5 A). Parapodia ovate, with two distal lobes ( Fig. 5 View FIGURE 5 A, 5B). Ventral cirri ovate ( Fig. 5 View FIGURE 5 A). Compound heterogomph chaetae, about six to seven per parapodium. Blades of dorsal chaetae slender, distinctly bidentated, both teeth similar, with short spines on margin, becoming wider ventrally, with proximal tooth more prominent and somewhat longer than distal ones. Remaining chaetae slight dorso-ventral gradation in length, 20 µm above, 30 µm below. Two or three aciculae per parapodium, slender, distally pointed ( Fig. 5 View FIGURE 5 C). Pharynx with an incomplete denticled arc, with about 15 relatively large, conical teeth, and a conical anterior mid-dorsal pharyngeal tooth (fide Hartmann-Schröder, 1965).
