Menestho

Menestho is a genus of very small sea snails, pyramidellid gastropod mollusks, or micromollusks.

Shell description
The original description by Möller (1842) is brief and in Latin: "Animal pede elongato, angusto; ore simplici, membrana linguali destituto; tentaculis brevioribus, crassiusculis, oculos perparvos ad basin internum ferentibus. Operculo pauco-spirato. Testa conico-turrita."

Life habits
Little is known about the biology of the members of this genus. As is true of most members of the Pyramidellidae sensu lato, they are most likely to be ectoparasites.
