Fig. 8 J–L

Material examined

BRAZIL: 1-US-1 well, Laranjeiras Municipality, Sergipe State (depths of 996 and 1080 m); Massapê outcrop, Riachuelo Municipality, Sergipe State (samples MP-1515, MP-1516, MP-1518, MP-1519, MP- 1521, MP-1540, MP-1542, MP-1545 and MP-1547), approximate coordinates 10°06' S, 37°10' W.

Measurements

Hypotype (CP-765): carapace: length = 0.47 mm, height = 0.27 mm, width = 0.21 mm.

Hypotype (CP-767): left valve: length = 0.43 mm, height = 0.23 mm.

Remarks

The generic diagnosis follows Alexander (1933) and the suprageneric diagnosis follows Gründel (1976). Due to the paucity of well-preserved specimens, Eocytheropteron sp. 1 cannot be properly described.
