SUPERFAMILY CRANCHIOIDEA PROSCH, 1847 (63 SPECIES) Diagnosis: Small to massive adult-sized Oegopsida with modifications of the funnel–mantle locking apparatus; funnel–mantle locking apparatus reaching the anterior margin of the mantle; with two series of suckers in the arms; tentacle manus suckers usually in four series; mitochondrial gene trnM between rrnL and trnY in the following sequence: −rrnL −trnM − trnY −trnW −trnG −trnE. Synonyms: The superfamilies Ommastrephoidea Steenstrup, 1857b and Thysanoteuthoidea Keferstein, 1866 were described in a different sense than in the present work: the superfamily Ommastrephoidea included Brachioteuthidae, Ommastrephidae and Thysanoteuthidae according to Berry (1920). However, owing to our criteria the families Ommastrephidae and Thysanoteuthidae are included within the superfamily Cranchioidea. We therefore consider the names Ommastrephoidea and Thysanoteuthoidea as junior synonyms of Cranchioidea.
