Submitting Names & Associated Data to ITIS

ITIS partners have assemble scientific names and their classification to provide a taxonomy that is open and can be delivered and integrated into biological data management systems. The data is for anyone needing a referenced, expert validated species list with clearly established hierarchical relationships.

At ITIS we strive to communicate a comprehensive taxonomy of global species that enables biodiversity information to be discovered, indexed, and connected across all human endeavors. To that end, below are the ITIS data definitions. More information about ITIS data and their relationships is available in the ITIS Data Model.

Data Requirements

There are MANDATORY requirements for each scientific name submitted. The omission of any of these may result in processing delays for your data. These requirements are:

  1. Scientific Name

    Definition: The Latin name used to refer to a particular taxon of any rank (e.g., a subspecies, a genus, a family, etc.). The taxon author is frequently included when citing a scientific name, as it can help distinguish between different uses of the same name (such as homonyms).

        unit_name1=Acris, unit_name2=gryllus and unit_name3=dorsalis

    10. Further Comments:

      Note that unit_ind4 and unit_name4 should rarely be used. Under the International Code of Zoological Nomenclature (ICZN) quadrinomials (not considering the use of a subgenus name) are "unavailable", and normally would not be considered for addition to ITIS. According to the International Code of Botanic Nomenclature (ICBN), while quadrinomials (like hypothetical example Dichanthelium ovale var. addisonii subvar. americanum) are used with some frequency in the literature, they are not considered properly formed names. ITIS follows ICBN in re-forming such names within the Code's constraints; this does not constitute a nomenclatural act. The example given would be properly formed as Dichanthelium ovale subvar. americanum, though it may still have the variety as the parent. If necessary, ITIS will generally add quadrinomials in synonymy.

      Subgenera also pose a special case. ITIS stores subgenus records with the genus in unit_name1 and the subgenus in unit_name2 (in parentheses). Species in the subgenus are formed as usual (genus in unit_name1, specific epithet in unit_name2), and given the subgenus record as the "parent." The classification within the subgenus is thus maintained via the hierarchical parent association.

      Hybrid names can usually be accommodated, but would use the name fields differently from other scientific names. Please contact ITIS if you wish to submit hybrid names.

  2. Author(s)

    Definition The person(s) deemed solely responsible for the original description and naming of the taxon. Certain situations are handled differently under the ICBN (Plantae, Chromista, and Fungi), the ICZN (Animalia and Protozoa), and the ICNB (Bacteria and Archaea). Full author information is required at genus rank and below (i.e., species, etc.), and optional above the rank of genus rank (i.e., families, etc.).

    Input Rules Include the full author information in one field or element.

    Data Elements:

    1. Name: taxon_author

      SQL Data Type: VARCHAR

      Length: 100

      Default Nullity: NOT NULL

      Description: The author(s) associated with the name of a taxon.

      Table: Taxon_Authors_Lookup

      Validation Rules:

      • For authorities associated with the kingdoms regulated by ICZN (Animalia and Protozoa), the author(s) and the actual date of the publication in which the author(s) first described the taxon are required.
      • For authorities associated with the kingdoms regulated by ICBN (Plantae, Chromista, and Fungi), only author(s) is/are required. Note: Initially, authors/dates may not be available for all records.

      Input Notes:

      • This element should specify the person(s) deemed solely responsible for the original description and naming of a taxon.
      • Required for all names of genus or lower rank (genus, species, etc.); optional at family level and above.
      • Under the ICBN (Plantae, Chromista, and Fungi)
        • Revising author(s) responsible for the transferal of a species (or a name at any rank of species or below) to a different genus, or for certain rank changes (i.e., a subfamily name elevated to family rank) are added after the name(s) of the original author(s), which are then placed in parentheses.
        • Author names generally follow standardized abbreviations in these kingdoms, and names and abbreviations can be looked up in Authors of Plant Names: A list of authors of scientific names of plants, with recommended standard forms of their names, including abbreviations (Brummitt & Powell, eds., 1992), or online at the International Plant Names Index (IPNI).
        • The year of publication is usually not included, and is not required by ITIS.
      • Under the ICZN (Animalia and Protozoa)
        • The year should be included after the name of last author.
        • ITIS uses a comma and a space to separate the author(s) and year.
        • A revision in which a species or variety is transferred to a genus other than the original genus will result in parentheses around the author and year.
        • The revising author is not cited.
        • Author names are not abbreviated.
        • Changing ranks within the same genus (i.e., from subspecies to species) will not result in parenthetical authorship.
      • The International Code of Nomenclature of Bacteria (ICNB), governing Bacteria and Archaea, follows the tradition of including both original and revising authors (as with the ICBN), but years are also included.

      Examples:

      • Following the ICBN traditions:
        • (Nash) Gould & C.A.Clark
        • (Ashe) Freckmann
        • Bickn.
        • L.
        • (Miq.) Seem.
      • Following the ICZN tradition:
        • (Quoy and Gaimard, 1832)
        • Roper, 1968
        • (Frussac, 1834)
        • (Appellf, 1886)
        • Linnaeus, 1758
      • Following the ICNB tradition (with commas):
        • (Van Saceghem, 1915) Gordon, 1964
        • Stackebrandt et al., 1995
        • (Collins and Stackebrandt, 1989) Tamura and Yokota, 1994
        • Ophel and Kerr, 1990

  3. Rank

    Definition: The particular level in a taxonomic classification that a name occupies. For example,the taxonomic rank of Homo sapiens is species. ITIS follows the ICBN and ICZN regarding what ranks are recognized below the family level.

    Input Rules:

    • ITIS uses internal identifiers to associate names with ranks.
    • For the purposes of submitting data, the rank name is needed.

  4. Usage

    Definition: Current standing of a scientific name.

    Input Rules:

    • Each scientific name is categorized as in current use or in synonymy.
    • For Plantae, Chromista, and Fungi, usage can be "accepted" or "not accepted."
    • For Animalia, Bacteria, Archaea, and Protozoa, usage can be "valid" or "invalid"
    • If the submission is categorized as not accepted or invalid, an additional data element providing a reason is required. This "unacceptability reason" provides further clarification regarding why a name is placed in synonymy.

    Data Elements:

    1. Name: name_usage

      SQL Data Type: VARCHAR

      Length: 12

      Default Nullity: NOT NULL

      Description: Current standing of an occurrence of Taxonomic Units.

      Table: Taxonomic_Units

      Values List:

      • accepted (Plantae, Chromista, and Fungi)
      • not accepted (Plantae, Chromista, and Fungi)
      • valid (Animalia, Bacteria, Archaea, and Protozoa)
      • invalid (Animalia, Bacteria, Archaea, and Protozoa)

      Validation Rules: Choice lists are dependent upon the values associated with a kingdom.

  5. Parent

    Definition:

    An ITIS term denoting the taxon that is the next highest level from the subject valid or accepted taxon. The parent of a species is usually a genus; the parent of a genus is usually a family, and so on. This parent-child linkage between records is the basis for the classification hierarchy in ITIS.

    Notes:

    ITIS will need to connect your submitted name(s) to existing names before it (they) can be added to the ITIS database. If the direct parent of a given name in your list is not in ITIS, then we would need to look for its parent at the next higher level, and so on, until a connection can be made to the existing hierarchy in ITIS. All the intervening names will need to be added to the ITIS database along with your name; all pertinent names should be included in your submission. Please add the parent of any name you cannot find in ITIS (including parents of parents, etc.) to your list. There is rarely more than one intervening name to add, but it is possible that more would be needed.

    Input Rules

    • All valid/accepted names must have one and only one "parent".
    • The format for the "parent" entry in a given record is to include the full name AND author (if applicable) of the parent in one field.

    Examples:

    • Species=Homo sapiens; enter parent=Homo Linnaeus, 1758
    • Genus=Arum; enter parent=Araceae (this family does not have an author in ITIS)

    Further Comments:

    • If you are unable to provide the parent with your submission, please include one or more fields for whatever classification hierarchy information you have, or indicate the group to which the named taxon is a member (i.e., bird, mayfly, mushroom, etc.). These bits of information will help us identify appropriate specialists and references we might consult for verification. Again, incomplete submissions usually take longer to process.
    • "Incertae sedis" (uncertain seat/position) is a special circumstance where a name is considered valid or accepted but is of uncertain position in a classification (i.e., it is known to be in a particular order, but the family it should be assigned to is not known). This circumstance occurs in groups that are poorly known or for taxa that are particularly difficult to classify. If you wish to submit names that will involve the use of this concept, please contact ITIS.

    Back to top

  6. Associated Accepted Name

    Definition:

    • The scientific name, including author, of the valid or accepted taxon identified as the currently accepted name used for a given invalid or not accepted name.
    • Each name that is in synonymy (junior synonyms, obsolete combinations, etc.) must be connected to one accepted or valid name.
    • The concept of "parent" is not applicable in such cases.

    Notes

    • ITIS bases the "accepted name" linkage upon the current identification of the type specimen to which the name is anchored.
    • For all names from superfamily down to the lowest ranks, there should be a type (a specimen) to which the name is ultimately attached.
    • For higher ranks, there is a type taxon, but ultimately these too can be connected to a single specimen. The type specimen upon which the species name "Corallus enydris" was based is now identified as a member of the species "Corallus hortulanus." Thus, the "accepted name" for Corallus enydris is Corallus hortulanus.

    Input Rules

    As with "parent" links (see above), the full scientific name and author values from the parent record must be combined into one field in your submission file, in this case under the "accepted name" field.

  7. Unacceptability Reason

    Definition:

    An explanation regarding why a given scientific name is judged to be invalid or not accepted. Unacceptability reasons vary among kingdoms.

    Data Elements:

    1. Name: unacceptability_reason

      SQL Data Type: VARCHAR

      Length 24

      Default Nullity:NULL

      Description:The cause for an occurrence of Taxonomic Units being identified as not accepted/invalid under the usage element.

      Table: Taxonomic_Units

      Values List:

      Animalia, Bacteria, Archaea, and Protozoa Definition
      junior synonym The later established of two or more names of the same rank used to denote the same taxon. For species, the epithet and author(s) are different from those of the accepted name.
      original name/combination The form or combination (i.e., genus + species) of a name as published in the original description (= senior synonym). The specific or subspecific epithet is the same as that of the accepted name (allowing for gender/form changes) and the author(s) and date are never bounded by parentheses. For any given accepted name, there should be only one original name/combination.
      subsequent name/combination The form or combination (i.e., genus + species) of a name that is different from both the original and the currently accepted combinations (= names) and is used to denote the same species or subspecies. The specific or subspecific epithet (allowing for gender/form changes) and the author(s) and date are the same as for the accepted name (though the use of parentheses may vary). Essentially, this will be the case for any combination with the same epithet and authorship that is neither the original nor the currently accepted name.
      junior homonym The latter published of two or more names with the same spelling and used to refer to different nominal taxa (family and genus group names) or for species and subspecies, to different nominal taxa that were either originally (primary homonym) or subsequently (secondary homonym) combined with the same generic name. To be available, a junior homonym requires a replacement name and the replacement name is based on the same type specimen.
      homonym & junior synonym One of two or more names of the same rank and with the same spelling that were used to denote the same or different taxa. The older name (= senior homonym) may be available, or, for this specific unacceptability reason, may itself be the synonym of an older name for a different taxon. No replacement name is needed for a homonym that is also a junior synonym.
      unavailable, database artifact A name that is misspelled in the ITIS file, cannot be verified by any reference or expert, and likely resulted from a keystroke error, or any other database artifact (e.g., place-holders, common name entered as scientific name, etc.) that originated within NODC or ITIS.
      unavailable, literature misspelling A name that has been misspelled in the literature (i.e., not a database artifact).
      unavailable, incorrect orig.[inal] spelling A name that was incorrectly spelled in the original description; such errors must be corrected (emended) according to the Code of Zoological Nomenclature. A name with such a spelling is "unavailable" in that original, incorrect form.
      unavailable, suppressed by ruling A name that has been suppressed (made unavailable) for use in referring to a specific taxon by a ruling of the International Commission on Zoological Nomenclature.
      unavailable, nomen nudum A name published without sufficient descriptive information to satisfy the criteria of availability.
      unavailable, other A name that is unavailable for a variety of other reasons (e.g., non-binomial, anonymous after 1950, etc.) not covered in the previous list. This is essentially a catch-all category for other reasons for unavailability.
      unjustified emendation A change or correction (emendation) in the spelling of a name that was shown subsequently not to have been needed, to be unsupported by the International Code of Zoological Nomenclature, or to have been improperly published.
      unnecessary replacement A replacement name that was not needed, either because the original name was not a homonym or because a prior substitute name was already available. In instances where the replacement name itself was unavailable, use 'unavailable, other' or 'other, see comments' as the reason.
      nomen oblitum A reversal of precedence where a senior (older) name that has been forgotten (lost) is judged to apply to a taxon that has been known for many years by a younger name. The older name is formally placed in the synonymy of the younger name; the older name remains available, but does not take precedence. The junior name, which has taken priority, may be called a "nomen protectum."
      misapplied An indication sometimes used in the literature to refer to a misapplied name or a name incorrectly applied to a species (i.e., a misidentification). Use of this reason is strongly discouraged in ITIS (the name may be valid or accepted, just not as applied).
      pro parte An designation sometimes used in the literature to indicate that only some of the specimens referred to by a specific name in a specific reference actually represent that taxon. This may happen in a type series (syntypes) and can be troublesome if a lectotype has never been designated. This may be a misidentification or a consequence of incomplete knowledge. Use of this reason is strongly discouraged in ITIS.
      other, see comments Any other reason relative to unacceptability not covered above; typically a Comment is used to specify relevant issues. If you wish to do this, please contact ITIS at the email address or telephone number given above.
      nomen dubium A name having uncertain application because it is impossible to establish the taxon to which it should be referred. If you want to include a nomen dubium" in a submission, please contact ITIS at the email address or telephone number given above.

      Plantae, Chromista, and Fungi Definition
      synonym One of two or more names applied to the same taxon, but not to the same type (heterotypic); also used for non-current combinations of the accepted epithet (e.g., a usage placing the same species in another genus). For names in synonymy that ITIS would accept in a submission, this would be the only common unacceptability reason.
      homonym (illegitimate) Two or more identical epithets or combinations denoting different taxa of the family, genus or species-group, or of species or subspecies within the same genus (same name, different type). This is one of two kinds of illegitimate names, which must be rejected for the purpose of priority.
      superfluous renaming (illegitimate) A second validly published epithet applied to the same type as an earlier name (same type, different name). This is one of two kinds of illegitimate names, which must be rejected for the purpose of priority.
      rejected name A name which was explicitly rejected in the ICBN Appendices II-IV. Such names can be noted as "nom. rej." in the literature.
      invalidly published, nomen nudum A name published without sufficient descriptive information to satisfy the criteria of availability or valid publication.
      invalidly published, other Any case of "invalid publication" besides nomen nudum. This also includes names appearing in specified ranks within oppressed publications (Appendix V of the ICBN covers "opera utique rejicienda," or "entirely oppressed works").
      misapplied A name inappropriately applied to a specimen or distribution (for example, using the name of an endemic European species for a North American specimen). Such uses occur in checklists and other lists at times. Inclusion in ITIS submissions is strongly discouraged. Note that the name may be accepted, just not as applied in this case.
      pro parte Used in nomenclature to indicate that only part of the taxon (excluding the nomenclatural type) is being referred to. Inclusion in ITIS submissions is discouraged.
      horticultural A special kind of name for a plant that may or may not be found in nature. There is a separate nomenclatural code for horticulture that is not addressed in ITIS at present.
      database artifact Generally assigned to NODC or ITIS data that can't be verified by any reference or expert. May represent a keystroke error by NODC or ITIS, or a duplicate record. NOT used in ITIS submissions.
      orthographic variant (misspelling) Two or more different spellings of the same name.
      other, see comments This is reserved for anything that does not fall under the categories listed above. Please contact ITIS at the email address or telephone number above if you wish to use this reason.

      Validation Rules: This element is required when usage is set to not accepted (Plantae, Chromista, and Fungi) or invalid (Animalia, Bacteria, Archaea, and Protozoa). Only those reasons for a particular kingdom should be displayed.

      Further Comments:

      Generally, ITIS requires one or more references that support the submittal. You may wish to use a short identifying phrase (Wilson & Reeder, 1993) in your data file, and provide the complete bibliographic citation separately. We can add the full data in place of the shorthand. If you are dealing with original publications of a name (i.e., the reference in which a name was first published), please include a field or column to indicate that fact. In addition to traditional printed references (journal articles, books, etc.), ITIS can store other kinds of references. Experts and other sources, such as websites and databases are of interest to ITIS. Please contact ITIS if you intend to use any of these non-traditional references, or if you have any questions about how ITIS handles references and citations.

      If you cannot provide a reference for the name, any context you might have could help (i.e., it is from a stream survey from the Pacific Northwest of the U.S.).

  11. Vernacular (common) names

    Definition: a name other than a scientific name that is commonly used to refer to a species or other taxon. Examples are rainbow trout, red-winged blackbird, fence lizard, etc. The language (e.g., English, etc.) must be indicated for each vernacular name.

    Data Elements:

    1. Name: vernacular_name

      SQL Data Type: VARCHAR

      Length: 80

      Default Nullity: NOT NULL

      Description: A common name associated with an occurrence of Taxonomic Units.

      Table: Vernaculars

    2. Name: language

      SQL Data Type: VARCHAR

      Length: 15

      Default Nullity: NULL

      Description: Native language from which the vernacular name originates; e.g. American, English, Russian, Spanish, etc.

      Table: Vernaculars

    3. Name: approved_ind

      SQL Data Type: CHARACTER

      Length: 1

      Default Nullity: NULL

      Description: Designation identifying those vernacular names authorized for use by regulation, statute, etc.

      Table: Vernaculars

      Values List: Y/N If selected, the indicator will be set to true.

      Validation Rules: If the approved_ind is set to true, then the reference identifying the vernacular must be entered.

      Further Comments:

      • ITIS tries to adhere to the standards for capitalization within specialist communities, where they exist. Otherwise we generally only capitalize proper nouns.
      • Language (of vernacular) — It can be exceedingly difficult and time-consuming (and often futile!) to categorize some vernaculars in terms of language. They often are transliterated and further altered over time such that they no longer correspond to any language, per se. Therefore, where there is no clear indication of language for a vernacular, ITIS categorizes a vernacular according to the language of the reference in which it is found.

  13. Jurisdiction information

    Definition ITIS supports the inclusion of information designating which of several North American political jurisdictions of interest to the U.S. and Canada the species is found. For each jurisdiction, the species can be assigned a value of "Native," "Introduced," "Native & Introduced," or "Incidental" (the species has been recorded for the jurisdiction, but is regarded as not established or naturalized, such as with a single exotic bird blown in by a storm, or escaped from captivity).
