New material examined
BRAZIL: São José 1 outcrop, Riachuelo Municipality, Sergipe State (sample MP-1552), approximate coordinates 10°44' S, 37°13' W.
Measurements
Hypotype (CP-682): right valve: length = 0.41 mm, height = 0.20 mm.
Remarks
The generic diagnosis follows Gramann (1963). Liasina sp. 1, in contrast to most Liasina species, is not smooth in lateral view, but rather pitted. The very restricted number of specimens does not allow a complete description of this probably new species. Specimens in Viviers et al. (2000), namely Bythocypris ? sp. Se1, and Piovesan et al. (2013) also belong to Liasina sp. 1.
Paleoecology and distribution
Liasina sp. 1 is a marine, shelf species occurring in the following localities and stages: Itanhaém and Itajaí-Açú Formations, Santos Basin, Albian ( Piovesan et al. 2013); Angico ( Viviers et al. 2000) and Taquari (present work) Members, Riachuelo Formation, Sergipe-Alagoas Basin, uppermost Aptianlower Albian, Aracajuia benderi zone (MSA-0), Sergipella viviersae subzone (MSA-0.2), Brazil.
