Description
Size: Length 0.52 – 0.56 mm.
Body cylindrical without demarcation between metasome and urosome and worm-like. Anal operculum prominent without setae. Antennule 6-segmented, the fourth with an aesthete. Exopod of antenna one-segmented with two terminal setae. Maxillule and maxilla much reduced. Maxilliped short with a terminal claw. P.1-P.4 are biramous with 3-segmented exopod and 2-segmented endopod. Second endopod segment short with 2 terminal setae. Second endopod segment of P.2 and P.4 and third exopod segment of P.4 with modified setae. P.5 is a triangular plate with 4 setae. Egg sac simple, with 5-9 eggs arranged in 1 or 2 rows. Sixth leg in male is a semicircular lamina with an inner spine and an outer seta. Considerable variability occurs in this species in the structure of caudal ramus and its terminal claw.
