Lectotype a type specimen selected from a group of syntypes Name-bearing type Neotype : a replacement for the holotype Paralectotype : a remaining syntype once the lectotype and any isolectotypes are excluded (bot.) Paratype : a member of a type series apart from the holotype or isotype (zoology); a syntype that is not a member of the type series (botany) Syntype : a specimen cited in the original description of the taxon (botany) Type locality or location: where the type specimen was found Type host: in parasitology, the host species from which the type specimen was recovered Rank names The main ranks are kingdom (regnum), phylum or division (divisio), class (classis), order (ordo), family (familia), genus and species. The ranks of section and series are also used in botany for groups within genera, while section is used in zoology for a division of an order. Further levels in the hierarchy can be made by the addition of prefixes such as sub-, super-, infra-, and so on. Divisions such as "morph", "form", "variety", "strain", "breed", "cultivar", hybrid (nothospecies) and "landrace" are used to describe various sub-specific groups in different fields. It is possible for a clade to be unranked, for example Psoroptidia (Yunker, 1955) and the SAR supergroup. Sometimes a rank is described as clade where the traditional hierarchy cannot accommodate them. Latin descriptions of names or taxa Note that in zoology the English descriptions, such as "conserved name", for example, are acceptable and generally used. These descriptions can be classified between accepted names (nom. cons., nom. nov., nom. prot.) and unaccepted combinations for different reasons (nom. err., nom. illeg., nom. nud., nom. rej., nom. supp., nom. van.), with some cases in between regarding the use (nom. dub.: used but not fully accepted; nom. obl.: accepted but not fully used, so it yields precedence to a nom. prot). Candidatus (Ca.) - a taxon proposed from incomplete information, such as uncultured bacteria known from metagenomics ex errore – made in error incertae sedis – of uncertain placement nomen alternativum (nom. alt.; plural: nomina alternativa) – an alternative name, as for certain plant families nomen conservandum (nom. cons.; plural: nomina conservanda) – a conserved name nomen dubium (nom. dub.; plural: nomina dubia) (zoo. bact. bot.(informal)) – a name of questionable application nomen ambiguum (plural: nomina ambigua), (bot.) a name that has been used with more than one meaning nomen confusum (plural: nomina confusa),
