Abralia fasciolata
Kotaro Tsuchiya
Introduction
A. fasciolata is a very distinctive species. It is easily recognized by its striped photophore arrangement on mantle. This species is similar to A. marisarabica in the mantle photophore arrangement, buccal rappet connectives and eye photophores, but is easily distinguishable by its larger mature size, and the larger number of integumental photophores on the mantle.
Characteristics
- Tentacle clubs
- Two or three hooks on ventral side.
- Two rows of large suckers on dorsal side of manus.

- Integumental Photophores
- Ventral mantle with six broad longitudinally arranged stripes of integumental organs which become diffuse posteriorly.
- Ventral head with seven longitudinally arranged stripes of integumental organs; unpaired middle row is with few photophores.
- Buccal connectives.
- Buccal-support connectives attached to the dorsal side of Arm III (DDDD-type).
Comment
This species is similar to A. marisarabica and A. dubia in its strange arrangement of buccal connectives and unusual eye photophores.
Nesis (1993) suggested this species is a synonym of the poorly known species, Abralia dubia (Adam, 1960).
