Pseudotheca Redlich 1899 Helcionella is a genus of helcionellid, a fossil marine invertebrate animal that is considered to be a mollusk and may possibly be a gastropod.

The shells of these animals are about a centimetre in size.

The tip of the shell extends beyond the rear extremity of the shell's aperture, and the shell is "endogastric" in shape.

[1] Helcionella is the type genus of the family Helcionellidae.
