DIAGNOSIS (English translation courtesy of the Prof. Lanlan Zhang). — “Bilateral symmetry, composed by a homothetic-triangular inner framework and an outer shell. The outer shell supported by the upper part of triangular framework. No pore on surface. Quadrilateral in side view. Suborbicular in both the front and back view. Triangular wing developed at the top. Aperture heart-shaped. Upper-part wide, bottom-part narrow. B-axis of the triangular inner framework extended out, formed a double cross in the bottom (of the triangular framework). Meshwork developed under the b-axis.”

REMARKS

Original publication by Feng (1992) was a photograph without any description. Although the above description was later included in Feng & Liu (1993b: 550) this work appeared in September 1993 and post-dated the May 1993 formal diagnosis of the genus Protoholoeciscus by Aitchison (1993a). Thus, Cangyuanella is regarded as the junior synonym of Protoholoeciscus.
