Nomenclatural Iype: The nomenclatural type is that constituent element (a specimen, or a description or a figure) of a taxon to which the name is permanently at- tached. This need not be the most typical or representative element but is the original material on which the description of the taxon is based.
(a) Holotype: Specimen or other element designated by the author or used by him as the nomenclatural type. (b) Isotype: This is a duplicate of the holotype.
(c) Syntype: When more than one specimen are cited by the author without mentioning which is the holotype, each specimen is designated as a Syntype.
(d) Paratype: Specimens cited along with the holotype are designated as Para- types.
(e) Lectotype: This is a substitute of the holotype when that is lost and is to be selected from the isotypes. When no holotype was designated by the author a speci- men from the original material is selected to be the Lectotype.
(f) Neotype: When all original materials are missing a Neotype is selected from other materials. (g) Topotype:
