Remarks

epi-mesopelagic, sampling depth (off Malta): 3000 m. Overall Depth Range in Sargasso Sea: 0-1000 m (Deevey & Brooks, 1977, Station "S");
According to Vervoort (1965, p.113) this species is very closely allied to L. flavicornis, so much so, that it has probably been frequently cofused with the latter.
For Hülsemann (1966, p.717), Giesbrecht (1892) drew attention to the two forms ( L. gemina and L. flavicornis) and considered them to be variations of L. flavicornis. Tanaka (1963) also found L. gemina but retained the specimens in the species L. flavicornis, because the internal spine on the 2nd exopodal segment of P5 in the female was relatively longer than in Farran's (1926) desciption.
After Lapernat & Razouls (2002, p.19) the Itoh's index value = 587.6 (number of teeth: 9) on the right Md, and 632.1 on the left Md (number of teeth: 8).
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 4 corresponding to small filter feeding herbivorous and mixed feeding omnivorous (mostly broadcasters).
