Siogamaia Asamusi
''Siogamaia'' is a small genus of very small sea snails, Pyramidellidae, pyramidellid gastropod mollusks or micromollusks. This genus is currently placed in the subfamily Chrysallidinae of the Family (biology), family Odostomiidae. The genus was originally described as a subgenus of ''Tropaeas'' Dall & Bartsch, 1904, but was later erected to a full genus and placed within Chysallidinae by Schander et al. (1999). Shell description The original genus description (Nomusa 1936), states that ''Siogamaia'' is a shell of moderate size with many whorls. The outline is elongate-conical in outline. The surface is marked by weak axial ribs that are mostly shown in the earlier whorls. The interspaces between the ribs are smooth. The Aperture is obliquely ovate with a single distinct columellar fold. The outer lip is smooth within, Life history Nothing is known about the biology of the members of this genus. As is true of most members of the Pyramidellidae ''sensu lato'', they are most likel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...
