Rhynchelmis Gustafsoni
''Rhynchelmis'' is the genus of 30 species of aquatic oligochaetes from the Northern Hemisphere, with 11 species from North America and 19 from Eurasia. They are part of the family Lumbriculidae, which are among the largest of the microdriles. They are generally defined as having atria in segment X and spermathecae in segment VIII (Fend & Brinkhurst, 2000). The prostomium generally has a proboscis A proboscis () is an elongated appendage from the head of an animal, either a vertebrate or an invertebrate. In invertebrates, the term usually refers to tubular mouthparts used for feeding and sucking. In vertebrates, a proboscis is an elong ..., from which the genus has got its name. ''Rhynchelmis'' contains several subgenera, all of which have previously held genus rank: ''Rhynchelmoides'' with four species, ''Sutroa'' with six species, and ''Pseudorhynchelmis'' with nine species.

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 ...

Rhynchelmis Orientalis
''Rhynchelmis orientalis'' is a freshwater worm. It was described by Yamaguchi in 1936 from specimens collected on Hokkaidō is Japan's second largest island and comprises the largest and northernmost prefecture, making up its own region. The Tsugaru Strait separates Hokkaidō from Honshu; the two islands are connected by the undersea railway Seikan Tunnel. The la .... It can be distinguished from other species in the genus by the very long spermathecae running in several posterior segments into spermsacs, disconnected to the alimentary tract, as well as a vestigial anterior vas deferens. The genital elements are positioned in a fashion similar to that of '' Rhynchelmis vejdovskyi''. ''Rhynchelmis orientalis'' is pinkish to purplish, of variable size. The number of segments is between 196 and 245, and the setae are one-pointed. References {{Taxonbar, from=Q7321678 Lumbriculidae Animals described in 1936 ...
