a specimen or illustration selected to serve in place of a holotype, where all of the material on which the name was originally based is missing or destroyed; isoneotype: a duplicate of the neotype. cf. type.
A specimen or other element selected to serve as nomenclatural type as long as all of the material on which the name of the taxon was based is missing (ICBN Art. 7). Comment: One of the type categories designated by a later author. Although no rule requires a monographer to typify all legitimate names within the monographed group, the ICBN implies such responsibility by its repetition (Principle II, Art. 7, Art. 37, etc.) that typification is a cornerstone to assignment of names. The "Guide for the Determination of Types" (old ICBNs) implicitly emphasized the neotypification process. In the absence of an explicit holotype (viz. HOLOTYPE), it would seem wise to seek an implicit holotype before designating a neotype from specimens of holotype candidacy. All candidates for lectotypification should likewise be exhausted before neotypification is considered.
a specimen or illustration (see Art
When a holotype has been lost or destroyed, and there is a need based upon nomenclatural stability, then a specimen (ideally one of the paratypes) can be designated as a neotype (new type). This should only be done as part of a revisionary project. See also type specimen.
(ICZN) a specimen subsequently designated as the name-bearing type of a species or subspecies for which, it is believed, there no longer exists a holotype, lectotype, syntype(s), or prior neotype (i.e. type lost or destroyed) (ICBN) a specimen or illustration designated as the name-bearing type as long as all of the material on which the taxon is based is missing

The single specimen designated as the name-bearing type of a nominal species or subspecies for which no holotype, or lectotype, or syntype(s), or prior neotype, is believed to exist.
A specimen chosen as the standard bearer of a species or subspecies name for which none of the original type specimens exist.
A specimen selected as the type subsequent to the original description in cases in which the primary types are definitely known to have been destroyed. ( 14)
