Diagnosis
Diagnosis: Sepiolinae with fins rounded with large anterior
lobes, which do not reach the anterior mantle margin; fin length
about 50–80% mantle length. Suckers biseriate on all arms.
Tentacular club suckers in 4–8 longitudinal series. Nuchal
commissure narrow, not reaching over the ocular globes. A pair
of dumbbell-shaped photophores on ventral surface of ink sac.
Gladius absent. Ventral mantle margin slightly sinuate, without
any deep funnel indentation. Right arm I of male hectocotylised.
Hectocotylus tripartite: basal part with five suckers in two
series, two suckers in dorsal series and three in ventral series;
copulatory apparatus long, fleshy, tape like, formed by fusion of
two adjoining very elongate sucker stalks, no additional
modified structure on the arm (i.e. hook-like stalks); distal to
tape-like copulatory apparatus biserial suckers to arm tip (19
suckers in holotype, 23 suckers in paratype 2). Female bursa
copulatrix on right side of mantle cavity, open type (cf. Bello,
2020), roughly ear shaped.
