Original description: Cannobotryiada without tubes on the cephalis.

The genus Botryopera is the simplest form among the Botryodea, the shell consisting of a lobate cephalis only, without tubes or radial appendages. It may be derived either from Dictyospyris or from Archicapsa by development of the horizontal fold in the frontal face of the shell, and the corresponding internal frontal septum, which separates the larger occipital lobe from the smaller facial half; the latter may be divided again into paired frontal lobes, lateral buccal lobes, &c. Botryopera may be the common ancestral form of many Botryodea.
Remarks on original description: [Campbell [1954, p.D143] considers Botryopera Haeckel, 1887a to be an objective synonym of Lithobotrys Ehrenberg, 1844a. He designates Lithobotrys quadriloba Ehrenberg, 1844a as the type species of Lithobotrys and only by inference of Botryopera. Therefore, we consider Chediya's designation [1959, p.185] of B. cyrtoloba Haeckel, 1887a, p.1108, pl.96, fig.1, x500 to be valid.

Synonymized with Botryopyle Haeckel, by Popofsky, 1913, p.318]
