Description:
The cephalothorax is moderately large and widest towards the rear. The genital segment has a hemispherical shape with angular postero-lateral corners, and its hind border is somewhat transverse. The abdomen appears to have two segments and is long and slender. The postero-median lobe is one and a half times broader than the lateral lobes, and the posterior sinuses are wide open. The frontal plates are low, with small lunules. The fourth segment is fairly large. The caudal rami are large and oblong. The slender antenna’s basal segment contains a rounded process, while the distal segment is long and curved. The post-antennal process is simple, and the post-oral process is stout with a flange. The slender maxilliped lacks special armature. The base of the sternal fork is semicircular but highly flattened limbs are nearly circular. The distal exopod segment of the first leg has claws, a claw-like smooth seta, and normal lower setae. The exopod of the second leg consists of three claws, with the first two being strongly barbed and roughly equal in size, while the third is small and lacks barbs. The exopod of the third leg contains a short, stout, and flanged basal claw. The fourth leg is stout, four-segmented, and has five claws, with the first four being finger-shaped, and the fifth one being naked and spine-like. The fifth leg is lobe-like with three setae, and the sixth leg has one seta. The coloration of this organism is creamy and semitransparent.
