new species. In these cases, the partial synonyms are identified either by 1) including the
taxonomic author’s name as part of the partial synonym; 2) including “of authors” as part
of the partial synonym when many authors have used the partial synonym; or 3) including
“in part” as part of the partial synonym. Inclusion of these markers is to warn the user
from using the partial synonym as a general synonym. These are also referred to as “proparte
synonyms”.
Convention: A different version of a species’ name. Alternates may include the
inclusion/omission of a subgenus or a difference in the gender of the name. Because
subspecies were not recorded in the PICES database, subspecies are also considered
alternatives to the base species.
Nomen nudum: An invalid scientific name because the species was not originally
described with sufficient detail, and thus the name is considered “naked” (see
International Commission on Zoological Nomenclature; http://www.nhm.ac.uk/hosted-
Zites/iczn/code/index.jsp?booksection=glossary&nfv=true).
Misspelling: An incorrect spelling of a taxon that was erroneously incorporated into the
scientific literature. Only common misspellings are listed.
Misidentified: An incorrect identification assigned to a species. Misidentifications
specific to a publication but not to the original description of a species include the author
names (e.g., “Tellina (Angulus) meropsis of Coan 1971”; “Ensis californicus of authors
not Dall 1899 in part”) or region (i.e., “Macoma irus of NEP authors”) or a combination
of both (i.e., “Penitella gabbii of NEP authors, not Tryon, 1863”). Inclusion of the
author’s name keeps the misidentified species name from being incorrectly considered as
a general synonym.
Two nonstandard taxonomic definitions were used for a few species to better reflect their current
taxonomic standing.
Species Complexes: With increasing scrutiny, including genetic analysis, it’s becoming
apparent that several previously recognized “species” are composed of a number of
different, and often undescribed, species that have been referred to under the same name.
Because of their uncertain taxonomic position, species complexes are generally not
classified as nonindigenous. However, in a few cases, species complexes can be
classified as nonindigenous over some portion of their range based on their recent arrival
in an area or by possessing other attributes of nonindigenous species. We identify species
complexes by adding the suffix “Cmplx” to the name of the purported species. Because
of the taxonomic uncertainty, synonyms of species complexes are considered “ambiguous
synonyms”.
Provisional Species: Provisional species are “organisms suspected of being new species
or whose identities cannot be determined from available literature” (SCAMIT, 2012).
Thus, these species are considered to be valid species in a particular region even though
they cannot be assigned to an officially recognized species name. Provisional species can
