What is a lectotype in biology?
A lectotype is a specimen later selected to serve as the single type specimen for species originally described from a set of syntypes. In zoology, a lectotype is a kind of name-bearing type.
What is the significance of lectotype?
Definition of lectotype : a specimen chosen as the type of a species or subspecies if the author of the name fails to designate a type.
What is a lectotype in botany?
Lectotype: A specimen chosen by a later researcher to serve as if it were the holotype. It is chosen from among the specimens available to the original publishing author (the isotypes, syntypes and/or paratypes) of a scientific name when the holotype was either lost or destroyed, or when no holotype was designated.
What is the meaning of lectotype?
How lectotype was chosen?
states that: “A holotype of a name of a species or infraspecific taxon is the one specimen or illustration (but see Art.

What is the difference between lectotype and paratype?
Paratype: A specimen not formally designated as a type but cited along with the type collection in the original description of a taxon. Lectotype: A specimen chosen by a later researcher to serve as if it were the holotype.
What if there is no holotype or paratype?
In most cases in which no holotype was designated there will also be no paratypes, since all the cited specimens will be syntypes. However, when an author designated two or more specimens as types (Art. 9.4), any remaining cited specimens are paratypes and not syntypes. 9.6.
What is the difference between isoisotype and lectotype?
Isotype: any duplicate specimen of the holotype. Lectotype: a specimen or illustration designated as the type when no holotype was indicated at the time of publication. If possible, the lectotype should be selected from the syntypes or original material. Isolectotype: any duplicate specimen of the lectotype.
What is a lectotype in a research paper?
Lectotype: a specimen or illustration designated as the type when no holotype was indicated at the time of publication. If possible, the lectotype should be selected from the syntypes or original material. Isolectotype: any duplicate specimen of the lectotype.
