Taxonomic applications of the esophageal flapper valve in the Genus Neonesidea (Bairdioidea, Podocopida, Ostracoda), including descriptions of new and poorly known species from the Caribbean and Gulf of Mexico Author Maddocks, Rosalie F. text Zootaxa 2021 2021-01-11 4903 4 451 492 journal article 8977 10.11646/zootaxa.4903.4.1 ec5ab0d0-05d0-493b-9359-2fbe1265656f 1175-5326 4431228 D8AA9035-EB27-4F50-9246-B5450D71F3E2 Neonesidea edentulata Maddocks, 2013 ( Figure 1 G–L) 2013 Neonesidea edentulata Maddocks : 502, Figs. 2 , 35–37. Material. Four specimens, including one male (3958M) and three juveniles. Dimensions. Male specimen 3958M, L 0.690 mm , H 0.373 mm . Supplemental description. The plate is wedge-shaped with nearly straight, rapidly converging edges. The posterior margin is smooth, except for a narrow but deep medial gap and very broad, deeply incised lateral gaps. There are no teeth, only two broad, low, smooth central ledges. The corners are asymmetrical horn-shaped flaps. The plate is thin, providing a clear view of the ventral setules. The ventral bracket is a simple V-shaped wall. Remarks. Superficially, the carapace somewhat resembles N. holdeni , with its exaggerated pilosity, but it lacks the plumose caudal setae and terminal spine. The plate strongly resembles those of N. bacata and N. florea . Distribution. French Frigate Shoals, the Hawaiian Islands.
