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

Parabohaidina tuberculata (sp. nov.)
(Plate I, Figure 9)

Description: The shell is flat, nearly rhombic in outline, wider than long, with broad, rounded sides at the equator and tapering to a more or less low cone at the tail. Two transverse folds of varying development are present in the equatorial region. The shell wall is thin, single-layered; the surface ornamentation consists of fine tubercles and coarse grains. The tubercles are 1.3-1.6 microns in diameter and about 0.5 microns high. The palaeostoma is palaeostomatous, indicated by a fissure in the apical region. A nucleus is present.

The holotype shell is 50 μm long and 57 μm wide.

This new species is distinguished from Parabohaidina verrucosa Jiabo by its fine tubercles.

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