New material examined

BRAZIL: 1-CPB-1 well, Carmópolis Municipality, Sergipe State (depth of 222 m); Massapê outcrop, Riachuelo Municipality, Sergipe State (samples MP-1514, MP-1515, MP-1517 to MP-1522, MP- 1534, MP-1538, MP-1541, MP-1543, and MP-1545 to MP-1547), approximate coordinates 10°06' S, 37°10' W.

Type locality and age

Camin 3/55 well, Germany; upper Albian.

Measurements

Homeotype (CP-705): right valve: length = 0.48 mm, height = 0.30 mm.

Homeotype (CP-706): left valve: length = 0.49 mm, height = 0.28 mm.

Remarks

The suprageneric diagnosis follows Gründel (1977) and Liebau (2005), while the specific diagnosis is based on Gründel (1966). Although the present species and Neocythere ? pseudovanveeni Gründel, 1966 are similar in size and general layout, the style of ornamentation and lack of distinctive morphological traits, i.e., the dorsal marginal flange and the pair of ventral ribs, leave the attribution to the former uncertain. Specimens identified as Neocythere GA B 21 in Grosdidier (1979) and Perissocytheridea ? sp. 1 in Piovesan et al. (2013) also belong to Neocythere ? aff. pseudovanveeni .
