The specimens from the Sakhalin Island (Fig. 8

<normalizedToken originalValue="C–E">C-E</normalizedToken>

) show that the posterior median notch is always wide, but there are some changes with size. For example, from smaller to larger specimens, the anterior corners become less prominent whereas the diagonal rib and the fan ribs become more prominent. The relative posterior extension of the fan tends to become reduced and in even larger specimens, it may disappear completely.

von Marenzeller, 1879 has a rather peculiar nomenclatural history because it was the same author who proposed the species who later concluded (
|
||
<bibRefCitation author="von Marenzeller, E" journalOrPublisher="Annalen des Kaiserliche Naturhistorische Hofmusem, Wien" pageId="60" pageNumber="61" pagination="1 - 18" title="Annulaten des Beringmeeres." volume="5" year="1890">von Marenzeller 1890</bibRefCitation>

) it was a junior synonym of another species,

||
(Ranzani, 1817) originally described from the Mediterranean Sea. As stated below, these two species are different and the Japanese species must be clarified; consequently we propose and describe a neotype and provide illustrations for its diagnostic features (
|
||
<bibRefCitation pageId="29" pageNumber="30">ICZN 1999</bibRefCitation>
|
||
, Art. 75.3.1-75.3.3). Emil von Marenzeller worked in the Vienna Museum and was in charge of several invertebrate groups, including polychaetes; however, because he changed his mind about his own species, he might have sent away the apparently discarded type materials or destroyed them during dissection because Dr. Helmut Sattmann has informed us that there is no type material for this species (
|
||
<bibRefCitation pageId="29" pageNumber="30">ICZN 1999</bibRefCitation>
|
||
, Art. 75.3.4). Von Marenzeller made only two figures and a detailed description to emphasize that his new species differed by the relative rib development, and his illustration shows that the fan is truncate with a deep median notch and that the posterior shield corners are well-developed; these same features are shown by the neotype such that we regard it as consistent with the original description and illustrations (
|
||
<bibRefCitation pageId="29" pageNumber="30">ICZN 1999</bibRefCitation>
|
||
, Art. 75.3.5). The original type locality was Miya Bay, south of Nagoya, Honshu Islands, Eastern Japan and the neotype locality is the Boso Peninsula, Chiba, Eastern Japan, about 300 km away but along the same coast. Despite the fact that these two localities are not contiguous, they are very close to each other (
|
||
<bibRefCitation pageId="29" pageNumber="30">ICZN 1999</bibRefCitation>
|
||
, Art. 75.3.6), although there was no indication about depth or habitat for the original materials. The neotype has been deposited in the Coastal Branch of Natural History Museum and Insitute, Chiba, Japan (

is unique among the species in the genus because its shield fan is reduced along its median line, especially in larger specimens, such that the lateral fan portions are longer, reaching the posterior corners, but the median portion is very short, as if having a wide, deep median notch.
