- This article is not about formal zoological nomenclature; it describes terms that are sometimes used but have no standing under the ICZN.
Forma (literally Latin for form) is used in a series of terms and abbreviations to describe variation in animals, especially insects. The terms or abbreviations are appended to the binomen or trinomen. Many 'typical specimens' may be described, but none should be considered absolute, unconditional or categorical. Forms have no official status, though they may be useful in describing altitudinal or geographical clines.
forma geographica - f. geogr.
- If used, nowadays usually denotes a part of a cline; for example for intergrades between subspecies in their area of contact.
forma localis - f. loc.
- As "f. geogr." but only local, more restricted in occurrence. See also small population size.
forma alta - f. alt.
- Altitudinal features are not necessarily inherited, but may entirely be due to environment. The same applies to temperature or humidity-generated forms, such as:
forma vernalis - f. vern. (spring form)
forma aestivalis - f. aest. (summer form)
forma autumnalis - f. autumn. (autumn form)
aberratio - ab.
- May be used for a single individual, for a small group such as an individual and its offspring, or for atypical individuals (for example, albinos).
- Also used for commonly observed forms of a species, but in this case use of forma (f.) or morpha, accompanied by a descriptive name, is more conventional.
Notes:
- A morph is a similar concept with a less restricted occurrence. As neither is officially recognised terminology, application can vary but, generally, morphs occur without geographical or seasonal restriction, and may constitute a significant part of the population. For a famous example, see Peppered moth.
- Botanical nomenclature is much more complex, with the use of varieties, subvarieties, and forms being formally regulated by the ICBN.
