Fig. 7S Amphicytherura fragilis Piovesan & Nicolaidis, 2013: 247 , fig. 4.7a–d. New material examined BRAZIL : Estre outcrop, Rosário do Catete Municipality, Sergipe State (samples MP-1424 to MP-1431), approximate coordinates 10°41' S , 37°02' W . Type locality and stratum PAB-15 well at a depth of 1029 m , Espírito Santo State , Brazil ; São Mateus Formation, Espírito Santo Basin, Albian. Measurements Homeotype (CP-764): ♀ , left valve: length = 0.45 mm , height = 0.24 mm . Remarks The diagnosis follows Piovesan et al. (2013) . After a major review of the genera Amphicytherura and Aracajuia by Antonietto et al. (2013) , the species has been transferred to the latter. Paleoecology and distribution Aracajuia fragilis ( Piovesan & Nicolaidis, 2013 ) comb. nov. is a transitional to marine (shelf) species occurring in the following localities and stages: São Mateus Formation, Espírito Santo Basin, Albian ( Piovesan et al. 2013 ); and in the present work, Taquari Member, Riachuelo Formation, Sergipe-Alagoas Basin, middle Albian, Aracajuia benderi zone (MSA-0), Reticulocosta edrianae subzone (MSA-0.4), Brazil .
