Considerable modification of the classification below that level (for species and subspecies) is to be expected in Orthogeomys and Pleistocene taxa of Geomys when available specimens are studied.
Each of these taxa is retained as a subgenus of a single genus, Orthogeomys.
Wood revised the taxaof the subfamily Entoptychinae, and described the first Miocene genus, Dikkomys, of the Geomyinae.

Especially significant is the diversity of species inhabiting the present tropical environments; many of these have differentiated from related taxa to the south.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "taxa" in a variety of sentences. We hope that you will now be able to make sentences using this word.
