89 The naming of organisms (and plant communities)
holoparalectotype: (zool., unoff.) a specimen from a series of
paralectotypes (q.v.) that is of the same sex as the holotype.
holoparatype: (zool., unoff.) a paratype (q.v.) of the same sex as the
holotype.
holopathotype: (prok., unoff.) the single strain designated by the original
author as the type strain of a newly described pathovar.
holoplastotype: (zool., unoff.) the cast of a holotype; a plastoholotype
(q.v.).
holoplesiotype: (zool., unoff.) a hypotype (q.v.) of the same sex as the
holotype.
holosyntype, [holosyntypus]: (phyt.) erroneously used to replace
"holotypus" in the nomenclature of syntaxa.
holotype, [holotypus]: (1) the one specimen (zool.: except in the case of a
hapanotype, q.v.), or (bot.) illustration, or other single element (e.g.
in phyt. a designated relevé) used by the author or designated by the
author as the nomenclatural type (name-bearing type, type
specimen) of a taxon or (phyt.) syntaxon or (zool.) nominal species
or subspecies when the name (zool.: nominal taxon) was established
(i.e. at the time of its original publication); see also nominifer. (2)
(zool., obsol.) a genotype (q.v.)
homeotype, [homeotypical]: see homotype.
homocultype: a strain of a microorganism as far as possible identified with
the archecultype (q.v.), but from another source or isolate.
homodefinitional: (phyl.) based on the same phylogenetic definitions; see
synonym.
homoeotype: see homotype.
homoiotype: see homotype.
homologous: (1) (phyl.) of characters shared by virtue of inheritance from a
common ancestor; a character or character state shared by two
organisms (which may represent different species or clades) is said
to be homologous if that character or character state was present in
all of their ancestors back to and including their most recent
common ancestor. (2) (prok., unoff.) in serology, of the antigen used
