Type material. Holotype adult female deposited in collection of Zooplankton held at El Colegio de la Frontera Sur (ECO- SUR), in Chetumal, Mexico (ECO-CHZ-10336), collected from plankton on 6 June 2016 at station B, Hamsilos Bay, Sinop, Turkish coast of the Black Sea (35°02’36”E, 42°03’36”N); specimen partially dissected, with selected appendages mounted on slide in glycerine, sealed with Entellan®.

Diagnosis. (Female) Body length excluding antennules and caudal rami 0.933 mm (67.2% cephalothorax, 11% urosome). Oral papilla at 26% of cephalothorax length. Ventral part of “forehead” with few shallow, transverse striations. Antennules 38% as long as cephalothorax, three-segmented (fusion of segments 3 and 4). Among antennular setae, elements of 2v group remarkably long, element 3 long and setiform, element IIId reduced, elements b 1-5 unbranched. Outer apical exopodal setae of legs 1–4 spinulose externally, bearing short setules internally. Endopodal lobes of fifth legs unarmed, asymmetrical; exopodal lobes subrectangular, with two large, subequally long apical setae and one small medial seta, latter not exceeding exopodal lobe in length. Ovigerous spines separated at base, 70% as long as body. Anal somite smooth, lateral margins expanding posteriorly.
