Pseudokomewuia radiata
Pseudokomewuia radiata He Chengquan, 1984
He Chengquan, 1984 included this species in Pseudokomewuia subgen. Condocorpidia.
Holotype: He Chengquan, 1984, pl.5, fig.14
Age: Tertiary

Original description: [He Chengquan, 1984b] (translated from Chinese with Google):
Pseudokomewuia (Condocorpidia) radiata (sp. nov.)
(Plate V, Figure 14)
Description: The shell is rhombus-shaped in outline, with a smooth equatorial region and nearly equal upper and lower shells. It has a prominent sieve-like apex, a low conical shape, about 3.5 microns high and 10 microns wide at the base. The equatorial region bears one or two transverse folds, possibly related to the girdle. The endosome is present, closely attached to the outer layer, and distinctly separated from it only below the apex. The shell wall is thin; the surface is marked by low, evenly spaced radial ridges, clearly reflected in the contour lines. The ridges are about 1 micron wide and spaced about 2.5 microns apart. In the apical region, the radial ridges are generally blurred or absent. The apex is of the paleosteal type, formed by cracking of the apical region. A nucleus is present.
The shell is 52.5-60 μm long and 55-57.5 μm wide; the holotype is 60 μm long and 55 μm wide.
Origin: Shangsi, Guangxi; the second section of the Yongning Group.
