Explanation of format and abbreviations used on BDWD detail page
The BDWD detail record displays 14 fields of information,
which varies according to the kind of name. These fields and their content
are as outlined below. Users should be aware that the descriptions given
below are for the full content and for many records not details are currently
in the database. For example, the name field should include the author, year
and page of the original source publication, but sometimes this information
is missing.
Name contains the scientific name and associated
information, such as the author, year and page of the original publication.
For family-group and genus-group names, there is a single word followed by
author information, which may be a single name or a string of names separated
by commas and with an am before the last name. After the author string, there
is the year followed by a colon and page number. For species-group names
there may be as many as four words before the author string. There will
always be two word, an initial genus-group name followed by a species
epithet. However, for the species-group names first proposed as trinominals,
there will be also the epithet of the species with which the name with
combined and usually an aberration indicating the status (spp. = subspecies,
var. = variety, f. = form).
Type usually contain information about the type of the name.
For replacement names, emendations, misspellings, et cetera, this field an
indication of the action and the name affected. For example, "em. X-us
Smith,"is statement that the name is an emendation of X-us Smith. Other
abbreviation used are mssp. = misspelling of, n. n. = new name for; incosp. =
incorrect original spelling of,
For family-group names, this is the name of a genus along with its author
and year.
For genus-group names, this is usually the name of a species followed by
an abbreviation indicating the method of type-fixation (AU=Automatic;
FR=First revisor, only used for incorrect original spelling; IN=Indication
(typicus, etc.); MO = monotypy, MA=Apparent monotypy; OD = original
designation, PD=Present designation; SM=Subsequent monotypy; SD = subsequent
designation, TA =Tautonymy; UK=Unknown). Further information may be provided
if required by the method of type-fixation or nomenclatural status of the
name. For type-fixation which is in another source, the author, year and
page of the source is given immediately after the abbreviation.
For species-group names, this is the type-locality of the species
followed by indication of the kind of type-specimen, stage of the
type-specimen and the current depository of type-specimen. The abbreviations
used for the kind of type are: HT = holotype; LT = lectotype; NT = neotype;
ST = Syntypes; T = Type. For the life stage: A = adult; F = adult female; L =
larva; M = adult male; P = pupa or puparium; qualifers, such as ex = exuia
may be used also. The acronyms for the depository will be found in the
collection database in the tools section.
Status contains a status of the nomenclatural and taxonomic
status of the name.
Notes contains supplemental information about the name, such
as the author and year of the senior homonyms of preoccupied names. Certain
key phrases have been coded to ensure consistency in the database. These will
be removed in future version, but their meaning can be found in the standard
document.
Valid Name contains the current correct name for the name
record. For a family-group name this is the name of the appropriate category
which is valid, but the current data will always be a family name. For
genus-group names this may be either a genus or subgenus. For a species only
a species name is given. No subspecies are recognized by the BDWD.
For names of uncertain placement, an incertae sedis convention is used
(see Wiley 1981). An special name consisting of a lead * (asterisk) followed
by either F (=family-group) or G (=genus-group) and the name of the taxon in
which their placement is certain. For example, *FSyrphidae would be used for
name known to belong within the family Syrphidae, but not to any of the
defined subfamilies. See the BDWD standards document for more information on
this convention.
Family contain the appropriate family to which the name
record belongs.
Category contain the name of the taxonomic level that
applies to the name record. For species-group name, it is always species; for
genus-group names it may be either genus or subgenus; and for famil-group
names it may be subtribe, tribe, subfamily or family.
Range contains an indication of the area in which the taxon
represented by the name record occurs. For family-group and genus-group names
this indication is at the level of biotic regions and includes first an
indication for the area of occurrence of the type followed after a colon by
the area(s) of other included taxa. For valid species-group name there is
also a short description of the range.
Citation contains a bibliography reference to work that was
the original source of the name. Unfortunately, most name records have not
yet been linked to its bibliographic source.
Verification Code contains an quality assurance indicator.
See under QA for more information about these codes.
Authority contains the name or names of the specialists who
certified that the name record corresponds to current taxonomic and
nomenclatural standards.
Revision Date contains the date that the record was
certified by peer-reviewed. Or a warning that the record has not been
reviewed by a specialist. See under QA for more information about peer-review
and certification.
Kind of Name contains only the nomenclatural class to which
the name belongs, which are three: family-group, genus-group and
species-group.
Record# contains the unique key number that is attached to
each name record in the BioSystematic Database of World Diptera. This number
should be used when reporting problems with our data.
