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