Terebellides  sp. 2

Figures 11DView FIGURE 11, 35View FIGURE 35 C–D; Tables 1, 2

Material examined. One specimen (NHMD-231449, Table 1).

Description. Complete specimen, not well-preserved, 11 mm long and 1.0 mm wide ( Fig. 35View FIGURE 35 C–D), mature female, with numerous intra-coelomic oocytes. Anterior thoracic segments (TC1−5) ventrally white. General bran- chial structure not well defined because the state of preservation, not clearly corresponding to any species described in this work.

Distribution and bathymetry. South Africa (off Cape Point); 110 m depth ( Fig. 11DView FIGURE 11; Table 1).

Remarks. Terebellides stroemii  was widely reported by Day (1967) along the coasts of South Africa, including Cape Point, nearby where this specimen was collected. This author provided a brief description of his material but did not mention explicitly where it was collected. However, these specimens clearly differ from Terebellides  sp. 2 at least in two characters: larger body size (up to 70 mm) and a much larger shelf-like mouth lower lip ( Day, 1967: Fig. 36.1. f-g). Moreover, Day’s drawings show well-developed anterior and posterior branchial lobes, posterior ventral ones being shorter than dorsal ones and not fused to the latter (although reported as “partially fused” in the description); such drawings illustrate the TC6 geniculate chaetae and the thoracic and abdominal uncini but, unfortunately, these characters could not be examined in detail in our specimen without causing irreversible damage. This set of characters does not allow us to assign this specimen neither to any of the above described species nor to Day’s material.
