Plecia Canadensis
''Plecia canadensis'' is an extinct species of ''Plecia'' in the fly family Bibionidae. The species is solely known from Early Eocene sediments exposed in central southern British Columbia. The species is one of twenty bibionid species described from the Eocene Okanagan Highlands paleobiota. History & classification The holotype fossil of ''Plecia canadensis'' was collected by Lawrence Lambe from outcrops of the Allenby Formation along the Tulameen River on 6 August 1906, and then subsequently described by Anton Handlirsch in 1910. The type description was published in his ''Canadian fossil Insects. 5. Insects from the Tertiary lake deposits of the southern interior of British Columbia'', along with a series of 19 other bibionid species. Handlirsch did not include the etymological derivation of species names in the volume. While reviewing the tertiary fossil bibionids of the Eocene Okanagan Highlands, Rice (1959) transferred almost all described species from the genus '' Pent ...

Hypotype
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...
