Oswaldella garciacarrascosai Peña Cantero et al., 1997: 358–361 View in CoL , figures 5, 14A; Peña Cantero and Vervoort, 1998: 36; Peña Cantero and García Carrascosa, 1998: 178; 1999: 214; Peña Cantero and Marques, 1999: 85.
Remarks. Oswaldella garciacarrascosai is well characterized by the absence of mesial inferior nematothecae in the hydrocladial internodes, the presence of two axillary nematophores and one ‘mamelon’ in the cauline apophyses, the shape of the hydrotheca, and the presence of only secondary hydrocladia (cf. table 1).
Ecology and distribution. Oswaldella garciacarrascosai was found from depths of 330 to 340 m on muddy bottoms off the south coast of the Weddell Sea. It was observed epibiotic on Bryozoa; fertile colonies were found in January and February (Peña Cantero et al., 1997).

Cantero and Marques, 1999: 85.
Remarks. Oswaldella gracilis is an uncommon species, characterized mainly by the shape of the hydrotheca, which is low and laterally depressed, the absence of mesial inferior nematothecae in the hydrocladial internodes, the presence of a single axillary nematophore in the cauline apophyses, and the presence of only first-order hydrocladia (cf. table 1).
Ecology and distribution. Oswaldella gracilis is known from off the south coast of the Weddell Sea, where it was collected at a depth of 440 m (Peña Cantero et al., 1997).
