Homeotype (CP-668): ♀, carapace: length = 0.56 mm, height = 0.30 mm, width = 0.20 mm. Homeotype (CP-669): ♀, right valve: length = 0.55 mm, height = 0.28 mm.

Remarks

Cytherella besrineensis ( Bischoff, 1964) comb. nov. was initially assigned by Bischoff (1964) to the genus Cytherelloidea , although it did not present any ridge on its lateral surface, which is diagnostic of that genus ( Alexander 1929). Therefore, we transfer it to Cytherella , based on ornamentation similarities.

Paleoecology and distribution

Cytherella besrineensis comb. nov. is a marine, shelf species occurring in the following localities and stages: Talme Yafe, Rama, Telamim and Yavne Shales Formations, Levantine Basin, Israel, Aptian– Albian ( Rosenfeld & Raab 1983; Honigstein et al. 1985); Levantine Basin, Lebanon, Aptian–Albian ( Bischoff 1964); and Angico Member, Riachuelo Formation, Sergipe-Alagoas Basin, Brazil, middle Albian, Praebythoceratina amsittenensis subzone (MSA-0.3) ( Viviers et al. 2000); in the present work, also in the Taquari and Maruim Members, uppermost Aptian–Albian, Aracajuia benderi (MSA- 0) – Sergipella viviersae (MSA-0.2), Praebythoceratina amsittenensis (MSA-0.3) and Reticulocosta edrianae (MSA-0.4) subzones – and Aracajuia antiqua (MSA-1) zones.
