Amutatiola n. gen.

Diagnosis: Small Sepiolinae with fins rounded with large anterior lobe, which do not reach the anterior mantle margin; fin length about 40–66% mantle length. Suckers biseriate on all arms. Tentacular club suckers in 4–8 longitudinal series. Nuchal commissure moderately wide, not reaching over the ocular globes, about 38–59% of mantle width. A pair of dumbbell-shaped or elongated kidney-shaped photophores on ventral surface of ink sac. Gladius absent. Ventral mantle margin slightly sinuate, without any deep funnel indentation. No arm in mature males hectocotylised. Some arm suckers in mature males grossly enlarged. Female bursa copulatrix closed type, pouch-like, opening at level of base of left gill.

Type Species: Amutatiola macroventosa n. gen., n. sp. by monotypy.

Etymology: Generic name Amutatiola is derived from Greek a meaning without or absent plus Latin mutatus meaning changed or altered; the ending - ola is the diminutive suffix of sepiola meaning a small cuttlefish. The name denotes the unique feature among the Sepiolinae of having no arm hectocotylised in males.
