Dipolydora sp. Fig. 7P

Larval morphology.

Overall body shape slender. Prostomium small and rounded anteriorly. Anterior margin of prostomium has weak yellow-brown pigment. Three pairs of black eyes present in transverse row, most lateral pairs double-eyes. Black pigmentation on lateral peristomium absent. A pair of dorsal black spots present on chaetiger III onwards. A small medial spot of black pigment on posterior margin of chaetiger III. Some black pigment occurs on pygidium. Ventral pigment absent. Gastrotrochs occur on chaetigers III and V.

Remarks.

No adult individuals of this species were collected in the present study. The 18S and 16S rRNA gene sequences obtained from larvae in the present study did not match any available Dipolydora sequences. As the larvae specimens formed a monophyletic clade with the other Dipolydora species (excluding D. armata, D. capensis 1GG, D. cf. commensalis, and D. quadrilobata) with robust statistical supports (Figs 2, 3), this species was referred to Dipolydora sp.
