In the females the lower antennular flagellum is 11 to 14 segmented. The structure of the genital area is similar to that of Acetes chinensis, but the third thoracic sternite is produced backwards more strongly and the emargination of its posterior margin is shallower than that of Acetes chinensis.

In the males the lower antennular flagellum is 10 to 12 segmented; there are 2 clasping spines which have irregularly arranged tubercles on the distal inner surface; the first segment of the main branch has a basal spinule and a swelling; the segment opposite the tip of the longer clasping spine has 3-4 spinules; the following 4 segments each have 2-5 minute spinules distally. In the petasma the distal part of the capitulum is expanded like a bulb and has numerous hooks. The appendix masculina has 2 hooks.

The endopod of the uropod has 1 red spot on the proximal part in both females and males. The apex of the telson is usually rounded but it is truncated in a few specimens.
