Original description: [He Chengquan, 1984b] (translated from Chinese with Google):

Bosedinia tuberculata (sp. nov.)
(Plate VI, Figure 24)

Description: Oval in outline. The shell wall is thin and single-layered. The surface is finely tuberculated, irregular in size and shape, ranging from round to square. Round tubercles are 1.5-2.5 microns in diameter, while square tubercles are 2.5-5 x 2-3 microns. The tubercles are low, slightly reflected in the outline. A few coarse grains are also present. The palate is ancient, formed by a fissure in the top region; the operculum is connected. A nucleus is present.

The holotype specimen is 50 microns in diameter.

The paleostome of this species is likely to be apical, and it is tentatively classified within Bosedinia. This species is distinguished from other species in the genus by the fine (lumpy) tubercles on its surface.

Origin: Shangsi, Guangxi; the second section of the Yongning Group.
