[ZooBank LSID # for the specific name] Cymbasoma turcorum Suárez-Morales & Üstün, 2018: 547–551 , figs 2, 3 (unavailable; source paper deemed unpublished). 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. Etymology. A genitive plural noun honoring the people of Turkey , the country of the type locality. Remarks. A full description and taxonomic illustrations of C. turcorum , including comparisons to known congeners, was provided by Suárez-Morales & Üstün (2018) .
