Remarks

epi-mesopelagic, (off Malta: 2000 m).
Sampling depth (Antarct., sub-Antarct.) : 100-1000 m. Sargasso Sea: 0-1000 m (Deevey & Brooks, 1977, Station "S");
The species was observed in Antarctica by Vervoort (1951, 1957), but considered earlier as a synonym of L. wilsonae. For Vervoort (1951, p.151), the specimen from the Antarctic corresponds to Giesbrecht's concise description except for its slightly greater length and for the fact that the spine on the 1st basal segment of Mxp seems to be composed of some closely packed smaller spines; for the rest it agrees completely with Giesbrecht's account, and there is no doubt about its identity as L. aculeata. Afterwards Ramirez & Dinofrio (1976, p.44), Hopkins (1985, with doubt), Zmijewska (1987) report the species without taking into account a possible synonymy. Its presence, however, is confirmed in the Strait of Magellan.
The indication of the species in the extreme North Pacific seems surprising and requires confirmation.

Sewell (1947, p.258, Female) notes: The proportional lengths of the anterior and posterior regions of the body as 53 to 47. The proportional lengths of the segments of the posterior region (Th 5 to caudal rami) as 13 : 26 : 16 : 16 : 16 : 13 = 100. The anterior third of the genital segment is swollen and globular, and behind this the transverse diameter is sharply constricted.
Morphological characteristic after Bradford-Grieve & al. (1999):
Female: - In dorsal view, terminal spines of P5 do not extend as far as posterior border of genital somite.
Male: - Mxp terminal claw strongly curvede, inner edge with sharp step just proximal to bordering spinules adjacent to distal end of claw

After Ehrhardt (1967, p.888, 893) the species is found in the southwest Tyrrhenian Sea in water salinity between 37.31-37.78 p.1000.
