1994 Hampsia cooperi n. g. n. sp.; Morris 1994: 271–272, fig. 1A–G. 2008 Hampsia cooperi Morris, 1994 ; Baliński and Sun 2008: 112–113,

fig. 8.

Material.—Six almost complete shells, one dorsal and one ventral valve slightly covered by adhered grains of silica from samples MH 1 and D4.

Remarks.—This species is poorly represented in our collections. It has been described and discussed in detail by Baliński and Sun (2008). Externally, the specimens from China are very similar to Hampsia cooperi Morris, 1994 from the Viséan of Staffordshire ( England), which is the only known species of the genus.

Stratigraphic and geographic range.—The species is known from the Viséan of Staffordshire, England ( Morris 1994) and Tournaisian of southern China ( Baliński and Sun 2008 and herein).
