[1] The species is closest to Periclimenes indicus, P. obscurus and P. toloensis, resembling these species in the presence of an epigastric tooth on the carapace, the shape of the abdomen, the spinulation of the carapace, and the unarmed fingers of the first chelipeds.

From P. indicus, this species differs: by the greater size; by the much higher rostrum and the greater number of ventral rostral teeth; by the shorter eye; by the less slender antennular peduncle; by the more deeply cleft upper antennular flagellum; by the more robust scaphocerite; by the fingers of the first pereiopods (much longer than the palm); by the more slender pereiopods, especially the fifth, which is much longer than the ischium.

The upper margin bears nine or ten teeth, four of which are placed behind the orbit, the others are concentrated in the basal two-thirds of the rostrum.

A slightly larger immovable hepatic spine is placed below and a considerable distance behind the antennal.

The eyes are well developed, but relatively small; they reach only slightly beyond the middle of the basal segment of the antennular peduncle.

A sharp spine is placed on the outer margin of the antennal peduncle near the base of the scaphocerite.

The endopod of the fifth pleopod of the male is widened distally and has an irregularly rounded outline.

The exopod of the uropod has the outer margin straight and ending in a tooth, which at its inner side bears a movable spine.
