Abstract
The cheilostomatous bryozaan Smittina oblita sp.nov. is described from samples collected in the Patagonian Shelf and the Burdwood Bank (southwest Atlantic Ocean). This new species seems to be related to Smittina lebruni (Waters, 1905), and Smittina antarctica (Waters, 1904), from which it differs in its characteristic suboral avicularia.
Highlights
Smittinids are one of the most diversified groups distinct sutures (Fig. I).Frontal wall finely granuof cheilostomatous bryozoans, with around 25 gen- lar, perforsted by relatively few, evenly distribera
