Description:
The female of this species has an almost oval body covered by a carapace. The back upper corner of the valves is slightly below the maximum height, and the back lower corner is rounded with a row of spinules on the inner side. Longitudinal lines mark the valves. The rostrum is short, slightly pointed, and directed downwards. The antennules do not reach the apex of the rostrum. The labral plate is broadly rounded. The eye is larger than the ocellus and is positioned closer to the eye than to the tip of the rostrum. The postabdomen narrows towards the end, with 12-13 anal spines, the distal ones being very large. The last distal spine is followed by a small spinule near the claws. The claws bear a long basal spine. The length of the female is approximately 0.60 mm. In terms of reproduction, this species utilizes parthenogenesis. The parthenogenetic female progresses through multiple adult stages and produces batches of eggs, which are not released externally but are instead incubated within the mother’s brood pouch. Embryonic development occurs entirely within the brood pouch, and the young are subsequently released as juveniles.
