Zoological Nomenclature Flashcards
What is the criteria of publication?
A previously undiscovered species must be correctly published abiding to the rules of the code.
What is the criteria of availability?
A name must be correctly published and available for usage (i.e. not a homonym).
What is the principle of priority?
The principle of priority states that the first author that published a name for a particular specimen gets precedence over later authors.
What is the principle of first reviser?
When two or more items have the same date of publication, the first person to discover can make a choice and publish it appropriately.
When should an author’s name be in parentheses?
If an author describes a species as one genus, and then that species is moved to another genus.
What do cf, aff, sp, and Ex. gr mean?
cf - Identification is provisional.
aff - relates a new undescribed taxon to a named taxon.
sp - specific or subspecific identification impossible or not attempted.
Ex. gr - Intended to articulate a less certain affinity.
? - Identification is uncertain.
What is the Principle of Typification?
Each nominal taxon in the family, genus or species groups has actually or potentially a name-bearing type. The fixation of the name-bearing type of a nominal taxon provides the objective standard of reference for the application of the name it bears.
What are the different type concepts?
- Type of a species name is a specimen
- Type of a genus name is a species
- Type of a tribe, subfamily or family is a genus
What are the different types of type?
Holotype, Paratype, Syntype, Lectotype, Paralectotype and Neotype.
What is an Isotype?
A duplicate of the holotype (usually only in algae, fungi and plants).
What is an Epitype?
A specimen related to an illustration that is the type of a name [only in ICN (algae, fungi and plants)].
