If used, four of the five subgeneric names mentioned above would contain only one species each.
These differences of Neotamias are so slight in comparison with the similarities (ten features mentioned above) that Neotamias here is accorded only subgeneric rank under the genus Eutamias, instead of generic rank.
The primary cause of the subgeneric differentiation is thought to have been geologic changes in the continental area.
The eastern species became completely isolated from the main group, accumulated mutations, and evolved into the subgeneric type Trinomys.
Subgeneric rank is here accorded to the two groups of Proechimys characterized immediately above.
Other characters, however, appear in one subgeneric group and not in the other.
The interrelationship among the species is evident, not only because they have the same subgeneric characters, but because the full species themselves provide successive steps in a stairway of increasing specialization from P.
When, on the other hand, the two groups of species have mutually exclusive characters and a species with intermediate characters is unknown, the two groups of species can conveniently be accorded separate subgeneric rank.
The distinction is valueless as a subgeneric character, not only because the character is not constant in the species in the subgenus but also because there is subspecific variation in number of laminae in the cheekteeth.
Salix polaris belongs to a subgeneric group containing 29 species, which are arranged in four sections, that to which S.
This is a much more interesting species than the last, as belonging to a generic or subgenericform not hitherto recognised below the Carboniferous, and having its minute structure in part preserved.
All of the late Pleistocene records pertain to the subgenus Cratogeomys (long in use as a generic name but in the present paper reduced to subgeneric rank in the genus Pappogeomys).
Even so, in my opinion, the differences are insufficient to warrant even subgeneric recognition.
In my opinion these features do not warrant subgeneric recognition; however, these characters do distinctly separate Thomomys bulbivorus from other groups of species, and the character of the molars suggests retention of a primitive trait.
When the early phylogeny of Geomys is better understood, Parageomys may serve as a subgeneric taxon in which the primitive species of Geomys can be grouped, but as of now Parageomys is arranged as a synonym of Geomys.
The conchologists of the west coast have preferred to apply to their shells, and indeed to employ in general use, a large number of subgeneric names in place of the ordinarily accepted generic ones.
Because Putorius nowadays is relegated to subgeneric rank under the generic name Mustela, we have for consideration the name-combination Mustela minuta (Pomel).
Subgeneric characters should be such as will clearly distinguish the animals of one sub-genus from those of another.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "subgeneric" in a variety of sentences. We hope that you will now be able to make sentences using this word.
