However, L. inermis can be recognized by its apical antennal scale bearing a strong, straight spine with 2 serrate small spines on the distal part of the outer margin. The lateral margin of the telson is slightly narrowing from the middle to posterior parts and is armed with a few short setae; the apical plate bears 4 apical spines and the middle part is armed with 4 short spinules and 2 long bristles (Casanova 1996).
