Taxonomy/Identity: The name refers to the reduced test thickness (= strong compression in the plane of biseriality) compared to the type-species C. pavonia and other species. With a comparably thin wall, fine septa and radial partitions, as well as the rudimentary character of the partitions, C. compressa can be regarded a primitive species of the genus Cuneolina differentiating it from all other species described. Some similarities exist to Vercorsella (ex Cuneolina ) tenuis ( Velić & Gušić, 1973) , a taxon from the Valanginian of Croatia (see Velić, 2007) and Albania ( Schlagintweit et al., 2008).

C. compressa View in CoL was originally described as a subspecies by Schlagintweit (1988) because of a smaller size and thickness compared to C. pavonia View in CoL . It is now elevated to a full species (see also the WoRMS catalogue – Hayward et al., 2025).

Confident Stratigraphic Range: Cenomanian – Coniacian.

Uncertain Stratigraphic Range: not applicable.

Geographic Distribution: So far recorded (with illustrations) only from its type-locality in southern Bavaria (Northern Calcareous Alps, Germany), from Italy and from far to the east in southwestern China (Tarim Basin). Velić (2007, p. 18) reported the species without illustration from the late Turonian of Croatia.
