Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Obelus Discogranulatus
An obelus (plural: obeluses or obeli) is a term in typography that refers to a historical mark which has resolved to three modern meanings: * Division sign * Dagger * Commercial minus sign (limited geographical area of use) The word "obelus" comes from (obelós), the Ancient Greek word for a sharpened stick, spit, or pointed pillar. This is the same root as that of the word ' obelisk'. In mathematics, the first symbol is mainly used in Anglophone countries to represent the mathematical operation of Division (mathematics), division. In editing texts, the second symbol, also called a Dagger (mark), dagger mark , is used to indicate erroneous or dubious content; or as a reference mark or footnote indicator. It also has Dagger (mark)#Modern usage, other uses in a variety of specialist contexts. Use in text annotation The modern dagger symbol originated from a variant of the obelus, originally depicted by a plain line , or a line with one or two dots . It represented ...

Xerocrassa Philamnia
''Xerocrassa'' is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Geomitridae. MolluscaBase eds. (2022). MolluscaBase. Xerocrassa Monterosato, 1892. Accessed through: World Register of Marine Species at: https://www.marinespecies.org/aphia.php?p=taxdetails&id=996348 on 2022-08-06 Some species of ''Xerocrassa'' are instead considered to belong to the ''subgenus'' ''Xerocrassa'', within the genus '' Trochoidea''; in those cases the species are listed under the generic name ''Trochoidea''. However, for other authors both taxa are not closely related being different genera. Taxonomy The genus ''Xerocrassa'' is divided in 3 subgenera: * ''Xerocrassa (Amandana)'' Fagot, 1891 * ''Xerocrassa (Xeroclausa)'' Monterosato, 1892 * ''Xerocrassa (Xerocrassa)'' Monterosato, 1892 Species Species in the genus ''Xerocrassa'': * ''Xerocrassa amphiconus'' (Maltzan, 1883) * ''Xerocrassa arturi'' (Haas, 1924) * '' Xerocrassa barcelo ...
