Diagnosis
Diagnosis as for the treated species Penilia avirostris (P. avirostris parthenog. female).
This genus was considered to contain several species (Richards, 1895; Kramer, 1895), all of which were subsequently lumped into Penilia avirostris Dana (Calman, 1917; Steuer, 1933). In the light of modern taxonomy, however, all specimens throughout the World Ocean should be re-examined (Korovchinsky, 1983, 1986, 1996; Onbé, 1997).
Treated species:
