Stylocerite reaches two-thirds of basal antennular article; anterolateral tooth of basal article reaches distal margin of second antennular article. Scaphocerite with distal tooth strong, overreaching end of scale (modified from Holthuis, 1952a).

Distribution: Tropical and Subtropical seas all over the world, except for the American western coast. Off Brazilian coast (Maranhão to São Paulo and Rocas Atoll (03o 52'S, 0 33o 48'W)).
