holotype

the single specimen designated or indicated as “the type-specimen" of a nominal species-group taxon (species or subspecies) by the author at the time of the original publication (or the single specimen when no type was specified but only one specimen was present for the description). If there are no other types (paratypes) then the holotype is termed "unique". If the holotype is lost or destroyed, a single specimen chosen ideally from the paratypes, is designated as the neotype (replacement holotype). If a species is split into two or more species, the name is retained by the species represented by the holotype, and a new holotype will have to be designated for each new species
