New material examined

BRAZIL: Penha outcrop, Riachuelo Municipality, Sergipe State (samples MP-1450 to MP-1453, MP- 1457 and MP-1459), approximate coordinates 10°42' S, 37°13' W; São José 1 outcrop, Riachuelo Municipality, Sergipe State (samples MP-1550 to MP-1558, MP-1560, MP-1562, MP-1565 to MP- 1570, MP-1572, MP-1573 and MP-1575), approximate coordinates 10°44' S, 37°13' W.

Type locality and stratum

Shimon-1 well, at a depth of 969 m, Israel; Talme Yafe Formation, Levantine Basin, Albian.

Measurements

Homeotype (CP-685): right valve: length = 0.44 mm, height = 0.23 mm.

Homeotype (CP-686): left valve: length = 0.44 mm, height = 0.22 mm.

Homeotype (CP-760): carapace: length = 0.41 mm, height = 0.21 mm, width = 0.22 mm.

Remarks

The specific diagnosis follows Rosenfeld & Raab (1983). The family Bythocytheridae has been thoroughly reviewed by Gründel & Kozur (1972), Schornikov (1990) and Schornikov & Mikhailova (1990), who restricted the range of Monoceratina Roth, 1934 to the Devonian–Permian. Therefore, the present authors reassign Patellacythere shimonensis comb. nov. to Patellacythere from Monoceratina Roth, 1928 , based on both morphologic and biostratigraphical affinities.

Paleoecology and distribution

Patellacythere shimonensis comb. nov. is a marine, shelf to neritic species occurring in the following localities and stages: Madiéla Formation, Gabon Basin, Gabon, upper Aptian–lower Albian ( Grosdidier 1979); Talme Yafe Formation, Levantine Basin, Israel, Albian ( Rosenfeld & Raab 1983); and Angico Member, Riachuelo Formation, Sergipe-Alagoas Basin, Brazil, uppermost Aptian–lower Albian ( Viviers et al. 2000); in the present work, extended to the Taquari Member, although restricted to the Aracajuia benderi zone (MSA-0), Sergipella viviersae subzone (MSA-0.2).
