FAMILY PSYCHROTEUTHIDAE THIELE, 1920

(ONE SPECIES)

Diagnosis: Large adult-sized muscular Oegopsida with buccal connectives attached to the dorsal borders of ventral arms; with two series of arm suckers; tentacles characteristic, with expanded clubs having non-uniform series of suckers, with large suckers with stalks devoid of neck constrictions; carpal locking apparatus in linear series; funnel–mantle locking apparatus straight, reaching the anterior margins of the mantle; glandular structures (possibly photophores) present on the tips of the ventrolateral arms in males and the dorsolateral and ventrolateral arms in females; gladius without conus.

Remarks: Not included in our phylogenetic analyses, but its position as sister group of Histioteuthidae is supported provisionally by its morphology ( Young & Vecchione, 2016a) and by the phylogenetic results of Lindgren (2010) and Lindgren et al. (2012).
