The number of aesthetasc tufts on the lateral antennular flagellum is variable (7–15), with the majority of specimens having 11 tufts. The number of segments in the accessory ramus is usually two or three. The number of spiniform setae on the P3 and P4 propodi varies from four to seven, with six being the predominant number for P3 propodus. Most specimens bear two (rarely one) spiniform setae on the P5 merus. The number of teeth on the diaeresis of the uropodal exopod is generally 15 or 16; only two specimens have more than 16 teeth.
