Description:
Female: The carapace is broadly oval, narrowing towards the back and extending into a long posterior spine. The dorsal surface of the valves is moderately arched and adorned with elongated, spaced-apart spinules that continue to the posterior spine, reaching behind the middle region of the ventral surface. The head protrudes dorsally into a pointed helmet, with a small rostrum. Well-developed antennular mounds are located close to the rostrum, and the eye is large while the ocellus is tiny. Fornices are prominent, extending into a spine. The first abdominal process is nearly twice the length of the second, and all processes except the first are distinctly pubescent. The postabdomen tapers towards the end, bearing 10-13 anal spines and groups of lateral setae. The stout, curved claws each have three setae. The ephippium is relatively broad, with obliquely placed egg chambers well separated by unmelanized ephippial matrix. The length of the female is 2.6 mm. Male: The valves of the male are oblong and narrow, with the head set off from the carapace by a distinct depression above the heart and anteriorly produced similar to the female. Fornices are well developed. The antennules are large and movable, each with a long flagellum. The eye is large, while the ocellus is moderately sized. The postabdomen is strongly sinuate. The length of the male is 1.1 mm. Reproduction occurs through parthenogenesis. The parthenogenetic female progresses through multiple adult stages and produces batches of eggs, which are not released externally but are instead incubated in the mother’s brood pouch. Embryonic development takes place within the brood pouch, and the young are released as juveniles.
