- with arms II having suckerless, filamentous tips and bearing numerous photophores proximally (only in males?).
Characteristics
- Arms

- Photophores
- Nine equally-spaced photophores on each arm II; photophores located in proximal third of each arm.
- Nineteen equally-spaced photophores on each arm III; photophores located in proximal two thirds of each arm.
