Description:
The female of this species has an almost spherical body, slightly longer than it is tall. The back upper corner of the valves is noticeable, while the rounded lower rear corner lacks denticles. The valves exhibit pentagonal or hexagonal reticulations but lack dots or pits. The rostrum is pointed and notched, while the head shield is rounded at the back. The antennules feature a sensory seta near the midpoint of the front edge. The labrum plate has a smooth, convex, and pointed apex without denticles. The ocellus is closer to the eye. The postabdomen is short, bearing 7-10 anal denticles and a protruding preanal corner. The claw has two basal spines and setae on its concave edge. The endite of the first leg has three setae, two of which are roughly equal in length, while the third is hook-shaped. The length of the organism ranges from 0.29 to 0.38 mm. In terms of reproduction, this species utilizes parthenogenesis. The parthenogenetic female progresses through various adult stages and produces batches of eggs. These eggs are not released externally but rather are kept and incubated in the mother’s brood pouch. Embryonic development occurs within the brood pouch, and the young are subsequently released as juveniles.
