- Entry Syntax -

Describes the syntax of an entry in the classification. Older pages may deviate from the syntax presented here. In time those pages will be replaced.


[Rank[?] ][?][‡|†]Name[™][ Authorship][ Details][ Links][ Note[?]][ SynType:Synonym[?]]
[Ref=RefRecent][; ][N=Count[([CompleteRecent][+CompleteExtinct])]]
[T=Period][; ][H=Habitat][; ][G=Distribution

The syntax has these parts:

Part Description
Rank Rank of taxon
? Rank uncertain
? Position uncertain (=incertae sedis)
Recently extinct
Name Name of taxon
Type species, genus, etc.
Authorship Authorship of taxon
Details Link to the Details page of the taxon. The Details page contains information on authorship, cross references to alternative and original entries of the taxon, and bibliography.
Links Link to the Links page of the taxon. The Links page contains related pages found elsewhere on the internet.
Note Additional note
? Note uncertain
SynType Type of synonym
Synonym Synonym
? Synonym questionable
RefRecent The most recent reference with respect to rank, spelling and position. See Reference Syntax
Period The geological period in which the taxon occurred.
Habitat The habitat of the taxon. See Habitat Syntax
Distribution The geographic distribution of the taxon. The distribution is usually incomplete! Taxa above the species level usually state the continent/ocean only. See Distribution Syntax
Count Total number of major taxa. Numbers between curly braces are implicit, e.g. by adding the numbers of the subtaxa.
CompleteRecent Indicates that the number of recent and recently extinct subtaxa is complete at a certain level.
CompleteExtinct Indicates that the number of extinct subtaxa is complete at a certain level.


The Name part has these colors:

Setting Description
Name The accepted name of the taxon in the current classification at the preferred position.
»Name A previous or alternative position of a taxon. Usually taxa that appear at a higher level on the same path to the root are omitted in the classification pages, but do appear in the details pages.
[Name] A name that is no longer valid in the current classification.

The Name part has these additional forms:

Setting Description
Name a) At the top of the page: The link refers to the parent taxon.
b) Elsewhere on the page: The link refers to the subtaxa.
"Name" An informal name, i.e. a name that is not validly published.
<Name> A name that only serves as a title, i.e. the entry does not refer to a taxon.

The Note part has these settings:

Setting Description
BW Not published in a consistently binomial work
CP Conditionally proposed
CS Nomen conservandum.
DB Nomen dubium
GN Not based upon a generic name
IL Illegal name
IP Imperfect name
IV Invalid name
MP Misprint
MS Misspelling
ND Nomen nudum
OB Nomen oblitum
PL Polyphyletic
PO Preoccupied name
RJ Nomen rejectum
RV Revived name
UA Unavailable name
UP Unpublished name

The SynonymType part has these settings:

Setting Description
AL Alternative name
AU Different authorship
EM Emendation (justified)
EU Emendation (unjustified)
HM Homonym
IN Included (=subjective synonym)
NW New name
PP Pro parte
SF Different suffix (e.g. -oidea vs -acea)
SI Synonym (objective or subjective)
SO Synonym (objective)
SP Different spelling
ST Different rank (status)
TF Transfer
TL Translation (-us vs -a; -i vs -ii; etc.)

The CompleteRecent and CompleteExtinct parts have these settings:

Setting Description
* Complete at lowest level, i.e. either species or subspecies level
s Complete at species level
g Complete at genus level
f Complete at family level
o Complete at order level
c Complete at class level
p Complete at phylum level
k Complete at kingdom level
