Description:
The organism has an almost oval body shape with rounded corners at the back of its valves, sometimes featuring longitudinal lines and polygonal patterns towards the rear. Its head shield has a rounded back edge and three main pores on the head, connected by narrow passages. The antennules don’t extend to the tip of the rostrum, and the antennae have spines on various segments. The labrum plate has a curved front edge, and the ocellus is smaller than the eye and positioned midway between the eye and the rostrum tip. The postabdomen is broad, with nine anal spines and lateral groups of setae. Its distal dorsal margin protrudes beyond the base of the claws, with a projecting preanal corner and a slightly concave anal margin. Each claw has a single basal spine. Its length ranges from 0.40 to 0.50 mm. Regarding its life cycle, it reproduces via parthenogenesis. The parthenogenetic female progresses through several adult stages and produces batches of eggs, which are retained within the mother’s brood pouch for incubation. Embryonic development occurs internally, and the offspring are released as juveniles.
