Material examined

BRAZIL: Massapê outcrop, Riachuelo Municipality, Sergipe State (sample MP-1520), approximate coordinates 10°06' S, 37°10' W; Porto dos Barcos 3 outcrop, Riachuelo Municipality, Sergipe State (samples MP-1460 and MP-1470), approximate coordinates 10°43' S, 37°10' W.

Type locality and stratum

Tarhzoute (9°44'50" W, 30°34'50.3" N), Morocco; Aït Lamine Formation; Azazoul Basin, middle–upper Cenomanian.

Measurements

Hypotype (CP-713): carapace: length = 0.39 mm, height = 0.18 mm, width = 0.19 mm.

Remarks

The diagnosis follows Colin et al. (2005). Additionally, Microceratina sp. in Babinot et al. (2009) is included in the synonymic list of Microceratina azazoulensis Andreu & Colin, 2005 . Chapmanicythereis ? sp. 1 in Hart & Critenden (1985) is also tentatively herein considered co-specific, as the figured specimen presents the same general shape, but not the ornamentation, which could be due to taphonomic processes.
