might belong to this same species but some differences were found by the authors. First, their illustrations and description were apparently based upon a specimen without anterior shield because the chaetal lobes are well-defined, and even the larger papillae, often forming sediment tubercles, were depicted without sediment at all. Second, in the Brazilian specimen falcate neurohooks start by chaetiger 6, whereas Ehlers indicated that they start by chaetiger 9, and although these chaetae are brittle, the difference is enough for distinguishing two similar species. Other body features are similar but more specimens are needed to clarify this potential wide distribution from
