N
name-bearing type
The type genus, type species, holotype, lectotype, series of syntypes (which together constitute the name-bearing type) or neotype that provides the objective standard of reference whereby the application of the name of a nominal taxon can be determined. (From the Glossary of the International Code of Zoological Nomenclature).
Nearctic
One of the eight terrestrial ecozones dividing the Earth's land surface.The Nearctic ecozone covers most of North America, including Greenland and the highlands of Mexico.
Not included are Southern Mexico, southern Florida, Central America, and the Caribbean islands which are are part of the Neotropic ecozone, together with South America.

nec
Latin: 'and not' (of); 'nor' (of), used to distinguish from a homonym. For example: Cheilosia antiqua Becker, 1894 nec (Meigen, 1822) indicates that the taxon described by Becker (1894) as antiqua Meigen, 1822 is not the same taxon as Meigen (1822) himself described under the name antiqua.
neotype
The single specimen designated as the name-bearing type of a nominal species or subspecies when there is a need to define the nominal taxon objectively and no name-bearing type is believed to be extant. If stability and universality are threatened, because an existing name-bearing type is either taxonomically inadequate or not in accord with the prevailing usage of a name, the Commission may use its plenary power to set aside that type and designate a neotype. (From the Glossary of the International Code of Zoological Nomenclature).
nominal taxon
A concept of a taxon which is denoted by an available name (e.g. Mollusca, Diptera, Bovidae, Papilio, Homo sapiens). Each nominal taxon in the family, genus or species groups is based on a name-bearing type (although in the latter two groups such a type may not have been actually fixed). (From the Glossary of the International Code of Zoological Nomenclature).
notopleural seta
notopleural setae (synonym)
notopleural setae
Setae placed on the notopleuron. If larger notopleural setae are present it may be possible to distinguish between the anterior notopleural setae and the posterior notopleural setae. Presence, absence and number of notopleural setae may be of diagnostic and systematic importance.
notopleuron
Lateral part of the mesonotum immediately posterior of postpronotal lobes. The notopleuron may be carrying several setae, the notopleural setae. If these are present it may be possible to distinguish between the anterior notopleural setae and the posterior notopleural setae. Presence, absence and number of notopleural setae may be of diagnostic and systematic importance.
