This species could have a Lessepsian origin in the Mediterranean Sea.
For Sewell (1914, p.236) this species resembles L. detruncata.
After Ueda & al., 1983 (p.167, Table 2) at Maizuru Bay (Japan): (1)-Shape and diameter of swarm, (2)-depth (m), (3)- swarming position.
(1)- Disc-shaped swarms (10-20 cm); (2)- 0.5-1 m; (3)- above bottom around algal belts.
This species belongs to the L. detruncatagroup (Fleminger, 1967).
