. (Amended from Norman and Lu47 and Reid39, and after Bello, personal communication.) Broad ligament between head and mantle; commissure greater than one-third of head width. Transverse suckers in two or more rows on normal (nonhectocotylised) arms. Stalked suckers in six or more transverse rows on tentacular clubs. Left arm 1 hectocotylised in mature males; distally with lengthened, columnar sucker pedicels, closely packed to form longitudinal “palisades”, bearing at tip embedded toothed suckers that are partially covered by fleshy cap, number of palisades proximally equal to that of regular sucker rows but reduced toward distal tip of arm; pedicels not bearing discretely demarcated rounded suckers; basal part of hectocotylised arm with normal suckers and sometimes with 1–2 finger-like papillae in ventral sucker row, sometimes bearing tiny sucker(s). Enlarged arm suckers usually present in male and sometimes present in females. Paired kidney-shaped light organs in mantle cavity, ventral, and closely adherent to ink sac. Gladius absent.
