The female of this species has an almost oblong carapace, with a broadly oval ventral margin. There is a long posterior spine that curves upwards. The head extends dorsally into a large crest or “helmet” above the heart. The rostrum is acute and often positioned away from the ventrolateral margin of the carapace. The antennular mounds are very small and located at a distance from the rostrum. The eye is moderately large, while the ocellus is minute. The first abdominal process is nearly twice as long as the second and sparsely covered with setules, while other processes are more pubescent. The postabdomen tapers towards the end and bears 11-14 anal spines. The claw is curved and has three combs with 11, 14, and 28 teeth respectively. The length of the female ranges from 2.9 to 4.0 mm. In terms of reproduction, this species employs parthenogenesis. The parthenogenetic female progresses through multiple adult stages and produces batches of eggs, which are then incubated in the mother’s brood pouch. Embryonic development occurs entirely within the brood pouch, and the young are subsequently released as juveniles.
