header=[neotype] body=[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.

header=[nominal taxon] body=[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).

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

header=[homonym] body=[In nomenclature the word homonym is used for identical but independently proposed names for the same or different taxa. For exampe: Ochromyia Lehrer, 2005 is a homonym of Ochromyia Macquart, 1835. As a rule, the junior (more recent) name (in this case Ochromyia Lehrer, 2005) is invalid.<br />

header=[taxon] body=[Plural: taxa.<br />
Systematic category used in scientific, biological classification, like species or family. For example, in Diptera, the family Tipulidae is one taxon, as is the genus Tipula and the species Tipula maxima. These taxa represent different levels in a hierarchical scheme. A taxon at a certain level usually exists of more taxa at a lower level (for example, species in a genus).<br />

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

notopleuron

Lateral part of the mesonotum
