In the males the lower antennular flagellum is 11 or 12 segmented; there are 2 clasping spines; the structure of the lower antennular flagellum is quite similar to that of Acetes natalensis and Acetes serrulatus but the projection from upper end of the first segment of the main branch is more prominent; the first segment bears 2 spinules at the base; the marginal spinule of the second segment is as long as that of the third segment; the segment opposite the tip of the longer clasping spine bears 4-5 spinules. The basis of the third pereiopod has no projection on the distal inner margin; the coxa lacks the tooth. The petasma lacks a pars astringens; the capitulum has a large ventral projection which is placed at right angles to the long axis of the pars media, with the tip directed towards the pars externa; there are numerous minute hooks on the distal and outer margin of both the capitulum and the ventral projection. The apex of the telson is truncated and bears a small tooth on either corner; occasionally one of the teeth may be missing.
