Sars 1896: table IV, fig. 12). 2 Drawings included in original description illustrate setae with smooth borders; description does not state whether they are smooth or setulose/plumose. 3 The mandibular palp second article of S. kunyensis bears two setae located at the same level; remaining species bear one distal and one proximal seta.
