For Hülsemann (1966, p.729) the species described under the name L. maxima by Sars (1925) differs from Steuer's species and also from L. aurita in the relative length of the caudal rami, which are nearly as long as the abdomen, and in the elongate anal segment. For this reason L. sarsi is proposed for the females described by Sars as L. maxima.
Sewell (1932, fig.94) figures a male which because of its obvious similarity to Sars' (1925, 1924: Pl57, fig.1) female must belong to the same species (= L. sarsi). Sewell's description does not agree with his figure (in the figure the furca is as long as the abdomen) which agrees with sarsi, and the description with aurita. For Hülsemann, Sewell found males of two species: the one shown in figure 94 (= sarsi, the other one described (p.295-297) (= aurita).
Because of the synonymies certain geographic distributions are to be confirmed.
