Antennulae (=A1) considerably shorter than epimera of the 4th segment (Cx 4); first article of the peduncle stout, subequal to head, the second shorter, the third very short and similar to the arts of the flagellum; flagellum scarcely longer than the peduncle, with 8 arts. Antennae (=A 2) slightly longer than antennulae; peduncle art 4, 5 about equal in length; flagellum subequal to flagellum of antennulae. Cx 2 (fig. 5) nearly ovate, twice as high as broad; Cx 3 somewhat rectangular, not wider than the second but considerably deeper; Cx 4 (fig. 6) very large, slightly deeper than Cx 3 and 1/3-1/4 longer than deep, being about as long as the first five segments of the thorax, the inferior margin regularly curved and the posterior convex in outline. Gn 1 (fig. 7) small and slender; merus triangular and distally broader than the carpus, which is not quite twice as long as broad and has the lateral margins parallel; propodus narrower but slightly longer than the carpus and narrowed distally; dactylus about half as long as the propodus. Gn 2 (Fig. 5) stouter; merus short triangular, carpus much broader than long and only slightly produced beneath the propodus; propodus about as long as the breadth of Cx 2, nearly twice as long as broad; palmar margin (Fig. 8) convex in outline, slightly oblique, with an acute lobe and a spine at the posterior angle, within which the top of the dactylus closes. P 4, 5 slender and nearly naked, P 5 basis slender, four times as long as broad, not wider than the merus. P 6, 7 slightly shorter than P 5, basis posteriorly dilated and squamiform in both pairs, but broader in P 7. U 3 ramus slightly longer than the peduncle.</paragraph>
