03E587B9FFB4FFA850F467A0D299E568.taxon	description	Description. Medium-sized carapace, heavily calcified, subrectangular to subquadrate, peripherally compressed in lateral view. Greatest height and width posteriorly. Dorsal margin straight but appearing somewhat sinuous due to the over-reach of the dorsal ornaments; posteriorly hidden by a horn-like tubercle. Ventral margin with a gentle oral concavity, obscured by the submarginal ornamentation; an ornate flange protrudes in the posterior half. Anterior margin slightly concave in upper 1 / 3, rounded in lower 2 / 3; three narrow elongated fossae adorn the anteromedian margin. Posterior margin with a small, blunt dorsal caudal process. Eye-tubercle rounded and prominent. Surface ornamented by coarse reticulae with fossae varying in shape and size, and predominantly longitudinal ridges. Delicate and numerous papillae cover most muri and the compressed peripheral zone. Two well-developed horizontal anteromedian ridges, typical for the genus, delimit three papillate huge submarginal fossae. The upper anteromedian ridge runs to the center, turns up, and subdivides into two branches, one reaching the ocular tubercle and another following backward by a short distance and then upwards reaching the horn-like tubercle. The lower anteromedian ridge runs back to the posterior ventrolateral tubercle and turns up raising a short vertical ridge that subdivides into two branches, the most robust follows to the center, the most delicate follows obliquely backward and upwards and splits becoming Y-shaped. Three subparallel horizontal ridges run in the anterior ventrolateral half. The uppermost reaches the posteroventral alar tubercle, folds obliquely up and backward, and follows very sinuously to the posterodorsal horn-like tubercle. RV with two small projections behind the posteroventral alar tubercle but only one in LV. A sinuous dorsal ridge begins in the eye tubercle and runs backward reaching the posterodorsal horn-like tubercle. Normal porecanals not numerous, sieve-type. Hinge gongylodont with somewhat atypical anterior and anteromedian elements. Anterior and posterior inner lamella moderately wide. Central muscle scars four adductors in a sub-vertical row, a C-shaped, anteriorly opened frontal scar, and two mandibular scars. Sexual dimorphism distinct: males more elongate, with inconspicuous lateral tubercles, and a longer and narrower posteroventral flange.	en	Luz, Nathália Carvalho Da, Coimbra, João Carlos (2022): Ostracods (Crustacea: Ostracoda) of the Vitoria-Trindade Chain, Southwestern Atlantic.

Loxocorniculum micropapillosum sp. nov. is easily distinguished from other species of Loxocorniculum mainly by its strong reticulae with fossae varying in shape and size and the muri covered by small papillae that also adorn the wide compressed peripheral zone. Stratigraphic range. Holocene. Occurrence and distribution. In the study area: Vitoria and Davis seamounts (Tab. 4). Also occurs in the Brazilian Northeastern shelf (Lat. 07 ° 45 ’ - 08 ° 03.5 ’ S, Long. 34 ° 31 - 34 ° 36 ’ W) (see references in the synonymy list).	en	Luz, Nathália Carvalho Da, Coimbra, João Carlos (2022): Ostracods (Crustacea: Ostracoda) of the Vitoria-Trindade Chain, Southwestern Atlantic.

03E587B9FFB7FFA950F464B6D558E151.taxon	discussion	Remarks. Schornikov (2011) discussed the problematic taxonomy of the family Loxoconchidae Sars, 1926, and its three subfamilies: Loxoconchinae Sars, 1926, Cytheromorphinae Mandelstam, 1960, and Nigeroloxoconchinae Reyment, 1963. However, most authors recognize only the first subfamily, as also assigned by Schornikov (2011). In his study, the author also created the subfamily Loxocaudinae, a special category to group together “ the genus Loxocauda and the four closest genera ”, as follows: Loxocauda Schornikov, Glacioloxoconcha Hartmann, Phlyctocythere Keij, Pseudoloxoconcha Müller and Sarmatina Stancheva. Regarding the genus Phlyctocythere, Schornikov (2011) considers that only the Paleogene nominal species with two subspecies should be attributed to that genus: P. eocaenica eocaenica Keij, 1958 and P. eocaenica oriunda Moos, 1973. According to him, five Phlyctocythere species studied by Bold (1988) from the Neogene of the Dominican Republic constitute a closely related group due to the “ identical costulae in the posteroventral region of the valves ”. Nevertheless, based on the presence of “ prominent small eye tubercles ”, and “ one species [P. curva] with incisions on the hinge bar and on the terminal teeth of the valve ”, Schornikov (2011) does not include the five Bold’s species in his new subfamily Loxocaudinae. The two new species of Phlyctocythere described below belong to the Miocene / Pliocene morphological group of five species studied by Bold (1988) in the Dominican Republic, Caribbean. Therefore, if we follow Schornikov (2011) the Bold’s species and those studied here should be grouped in a new genus. The present authors prefer to maintain these two Brazilian species in the genus Phlyctocythere, especially due to the precarious knowledge of this genus, which needs a thorough revision.	en	Luz, Nathália Carvalho Da, Coimbra, João Carlos (2022): Ostracods (Crustacea: Ostracoda) of the Vitoria-Trindade Chain, Southwestern Atlantic.

03E587B9FFB6FFA950F460EED262E67F.taxon	discussion	Remarks. Phlyctocythere christophei sp. nov. is an exceedingly rare species, previously recorded in open nomenclature on the Brazilian equatorial shelf by Coimbra et al. (1999 a). It resembles the Caribbean Miocene species Phlyctocythere curva Bold, 1988, differing mainly by the more elongate outline, less arched dorsal margin, absence of anterior faint reticulae and RV with only two ventro-posterior and posterior concentric wrinkles. P. christophei sp. nov. is very similar to P. apua sp. nov., diverging in the less spherical outline in lateral view, number and distribution of wrinkles, and a hinge lacking traces of terminal elements. Similar to other species attributed to the genus, all specimens of P. christophei sp. nov. have the posterior margin and the caudal process somewhat damaged. Stratigraphic range. Holocene. Occurrence and distribution. In the study area: Vitoria and Davis seamounts (Tab. 4). Also occurs in the Brazilian Northern shelf, from Orange Cape to the mouth of Pará River (see references in the synonymy list).	en	Luz, Nathália Carvalho Da, Coimbra, João Carlos (2022): Ostracods (Crustacea: Ostracoda) of the Vitoria-Trindade Chain, Southwestern Atlantic.

03E587B9FFB2FFB250F46393D681E0E9.taxon	discussion	Remarks. The species Auradilus convolutus, described by Brady (1868) for Mauritius, has long been absent in the literature. It was only with Hu’s (1979) work that it reappeared in the scientific literature, but it has received different names ever since. Although Brady (1868) designed only one LV in lateral view, it showed enough detail that, along with the description, the species could be identified relatively easily, as pointed out by Mostafawi et al. (2005). In this paper, we present a new and more complete list of synonyms, presenting some differences from that of Mostafawi et al. (2005, p. 132). Moreover, it is noteworthy that Radimella minor described by Hu (1979, p. 1, fig. 10) does not appear to be specific to Auradilus convolutus, as proposed by these authors. It is smaller than A. convolutus and differs in ornamentation in adults and juveniles. Stratigraphic range. Pleistocene to Holocene. Occurrence and distribution. In the study area, the species occurs in Trindade Island in the following localities: Lixo Bay, Racha Island, Crista do Galo Pool, Cabritos Beach, and Andradas Beach. It occurs also in other Brazilian territorial waters (Northern, Northeastern and Eastern shelves, Sepetiba Bay, and littoral of Santa Catarina State), the Indian Ocean, and the Western Pacific. In the fossil record, it occurs in the Pleistocene of Taiwan.

03E587B9FFAFFFB150F467E0D362E304.taxon	discussion	Remarks. This species, described by Coimbra & Carreño (2012) for Trindade Island, was firstly allocated within the genus Tenedocythere. However, Warne & Whatley (2016), after analyzing a range of species of this genus, found that fossil and living Tenedocythere occur exclusively in the Mediterranean region, placing all species outside this region in the genus Neohornibrookella Jellinek, 1993. Those authors proposed a new subfamily of shallow marine ostracods, Tenedocytherinae, which includes the phylogenetically related genera Tenedocythere, Neohornibrookella, and Bosasella. Neohornibrookella trindadensis was also recorded for the Caribbean region, erroneously identified by Bold (1988) in Late Miocene-Pliocene sediments of the Dominican Republic as Quadracythere producta (Brady, 1866). Yasuhara et al. (2018, 2020) discuss the frequent misidentifications between genera of the Family Thaerocytheridae and with some genera of Hemicytheridae (probably due to their monospecific origin), attributing this mainly to the lack of detailed images of the internal and external morphology of the species. Stratigraphic range. Late Miocene-Pliocene to Holocene. Occurrence and distribution. In the study area, the species occurs in Davis and Dogaressa seamounts and Trindade Island in the following localities: Príncipe Beach, Lixo Bay, Racha Island, Orelhas Bay, North Tip, Crista do Galo Pool, Cabritos Beach, Portugueses Bay, Calheta Beach, Andradas Beach and Tartarugas Parcel (Tabs. 3 and 4).

03E587B9FFABFFB550F46624D606E10D.taxon	discussion	Remarks. Polycope, the most diversified genus of the family Polycopidae, has been poorly studied in South America, including the Brazilian territorial waters. When recorded, the species are in open nomenclature (e. g., Drozinski et al. 2003; Bergue & Coimbra 2008). Some zoologists, such as Karanovic & Brandão (2015), claim that the carapace morphology of the polycopids would not be enough to distinguish the species. Although such a conclusion seems hasty, we prefer to keep the two species of Polycope in open nomenclature due to the analyzed material being only juveniles.	en	Luz, Nathália Carvalho Da, Coimbra, João Carlos (2022): Ostracods (Crustacea: Ostracoda) of the Vitoria-Trindade Chain, Southwestern Atlantic.
