Additional material examined: Benthoctopus rigbyae : * NMSZ 2002037.032 , RV Polarstern , 61°10'S 54°34'W (Antarctic Peninsula), Stn 61/048-1, 16 March 2002, 343 m, male, leg. & det. AL Allcock. 10 additional specimens from the Antarctic Peninsula detailed in Vecchione et al. (2009) preserved under catalogue numbers GoogleMaps NMSZ 2002037.030 - 031 and NMSZ 2002037.033 - 034 .

Diagnosis. Arms approximately 3–4 times ML. Arm formula variable. Funnel organ W-shaped. Gills with 5–8 lamellae per inner demibranch and 6–8 lamellae per outer demibranch. LLI 6–16 (mean 10). Maximum spermatophore length 102, maximum SpLI 110, maximum number of spermatophores 28. Mature males without enlarged suckers. Integument smooth.

Remarks. This species differs from Benthoctopus levis by the funnel organ ( VV in B. levis ) and arm length (shorter in B. levis ).
