Genus of molluscs

Parvaspina Tar River spinymussel (Parvaspina steinstansana) Scientific classification Kingdom: Animalia Phylum: Mollusca Class: Bivalvia Order: Unionida Family: Unionidae Tribe: Pleurobemini Genus: Parvaspina Perkins, Johnson & Gangloff, 2017 Species P. collina P. steinstansana

***Parvaspina*** is a [genus](/source/Genus) of [freshwater mussels](/source/Freshwater_mussel), [aquatic](/source/Aquatic_animal) [bivalve](/source/Bivalve) [mollusks](/source/Mollusk) in the [family](/source/Family_(taxonomy)) [Unionidae](/source/Unionidae). It contains only two [critically endangered](/source/Critically_Endangered) species, both endemic to river basins in a small region of the [southeastern United States](/source/Southeastern_United_States).[1][2]

## Species

- *[Parvaspina collina](/source/Parvaspina_collina)* (James River spinymussel)

- *[Parvaspina steinstansana](/source/Parvaspina_steinstansana)* (Tar River spinymussel)

Both species in this genus were formerly placed in other genera (*[Elliptio](/source/Elliptio)* for *steinstansana*, *[Pleurobema](/source/Pleurobema)* for *collina*) before both being placed in the new genus *Parvaspina* in 2017.[3]
