Description
Summary:Benthoctopus rigbyae Vecchione, Allcock, Piatkowski, Strugnell, 2009 Type material examined: Benthoctopus rigbyae Vecchione, Allcock, Piatkowski, Strugnell, 2009: 18 holotype USNM 1117765, RV Polarstern, 61° 14'S 56° 25.8' W (Antarctic Peninsula), Stn 42/022, 21 November 1996, 394- 412 m, male. Octopus levis Hoyle, 1885: 220 holotype BMNH 1889.4.24.43, RV Challenger, 52°59'S 73°33'E (Heard Island), Stn 151, 7 February 1874, 75 fathoms, male. 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 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).
