A new genus and new species of the family Tonicellidae are described. This species inhabits Chilean waters near Provincia Valdivia at depths of 0.5-1.5 m where rough seas and nearshore currents are present. It lives among barnacles and feeds on them. This new genus has some features that are typical for genera of the family Mopaliidae, namely Mopalia and Plaxiphora (Fremblia), but it has no caudal sinus in the tail valve and has two petal-shaped processes between the valves.
