Organism information awaits expert curation
Class: Maxillopoda

Size: Length 3 mm (male).

Body long and dorsoventrally flattened, anterior end with a prominent rostrum directed ventralwards and appear anteriorly as a semi-circular elevation. 3 free metasome segments with rounded lateral margins. Urosome six-segmented, more or less cylindrical, first segment fairly broad and postero-laterally drawn into triangular expansions. Caudal rami almost as long as the last urosome segment, slightly diverging and carrying four apical setae, second seta from the inner side longest. Antennules six-segmented, each of the 3 last segments with a long aesthete. Antenna with the first 2 segments carrying a long seta each, inner distal angle of second segment spiny, so also the inner border of third segment, its distal angle produced carrying a stout barbed claw and 3 setae, the fourth segment longer than broad, with 7 long setae. Mandible with 4 movable plates, first a stout chitinised claw, second a strongly barbed tooth and third and fourth pectinate spines. Maxillule a simple plate carrying 8 setae. Maxilla two-segmented basal segment with 1 small and 2 large spines, second segment with four stout spines. Maxilliped large and subchelate, three-segmented, basal segment internally produced into a spatulate process, the small third segment carries a very long, curved apical claw and two slender plumose setae.
