From editor or global species database
Type locality Boring on the upper shell valve of Anomia glabra (synonym to Anomia simplex d'Orbigny, 1853). Webster (1879) gives no precise locality, but the samples were from Northampton County, Virginia, deduced from his introductory comments to be collected in the muddy shallows between the mainland peninsula enclosing Chesapeake Bay, and the outer barrier islands, probably east of approx 37.3 N, 75.93 W [details]
Type material It is likely no type material exists according to Radashevsky & Williams (1998: 213). Other material described from the same article is present at the USNM, but a number of species are missing, including Polydora caeca [details]

Homonymy Polydora caeca Webster, 1879 is a junior secondary homonym to Leucodorum coecum Örsted,1843 when both are in combinations in Polydora (but L coecum is now in Dipolydora). Hartman (1943 in Loosanoff & Engle) described Polydora websteri, which L & E stated was a 'new name' for P. caeca Webster. Hartman herself does not indicate, except indirectly, that it is a replacement name for secondary homonymy of P. caeca Webster with P coeca (Örsted, 1843). Note that the two spellings 'coeca' and 'caeca' are regarded as the same for the purposes of homonymy. Hartman includes P. caeca Webster in the synonymy of P. websteri. Much later when P. websteri became a widely used name as a shellfish pest Radashevsky & Williams (1998) applied to the ICZN for P. websteri to be not treated as a replacement name for P. caeca Webster, as it was a different species, and not P. caeca. This application was granted in Opinion 1974 (ICZN 2001). Thus the status of P. caeca Webster is that it no longer has a replacement name. Under Article 59.3 "A junior secondary homonym replaced before 1961 is permanently invalid unless the substitute name is not in use and the relevant taxa are no longer considered congeneric …" Both these conditions now apply, thus P. caeca Webster is an available name that is possibly now valid again. The substitute name is not in use as it was agreed to be a different species (the issue stemming from a misidentification of P. websteri as the same species as P. caeca by Hartman), and removed from substitute status by action of the ICZN in 2001. Thus P. caeca Webster no longer has a replacement name and does not require one as a junior secondary homonymy no longer exists. [details]
