Taxonomic discussion: Plummer (1926) designated three cotypes to represent her new species and illustrated one view of each (dorsal, edge, and ventral). We have selected one of these cotypes (Plummer, 1926: fig. 11c ) as the lectotype for this species (Plate 14: Figures 1-3). The axial view of the lectotype is the view illustrated by Plummer to show the degree of compression of the test and the bluntly angular peripheral margin of the chambers of her new species. The chambers of the two paralectotypes are somewhat more inflated and the axial periphery of the test is somewhat less compressed than in the lectotype. Blow (1979) restricted his identification of G. compressa to morphotypes with compressed ogival chambers in axial view in contrast to morphotypes with an inflated rounded axial periphery, which he identified as G. cf. compressa or, if the chambers were more fully inflated, as G. planocompressa Shutskaya. Our studies separate compressa and planocompressa on the degree of compression/inflation of the chambers and the presence or absence of an imperforate peripheral margin. In the compressa -ehrenbergi-chapmani lineage an imperforate peripheral margin is a distinguishing characteristic, and the degree of compression of chambers in the ultimate whorl may vary from slightly compressed to the compressed ogival shape. In contrast, in the planocompressa -imitata -ovalis lineage the chambers in the ultimate whorl are fully inflated and the axial periphery is perforate. [Olsson et al. 1999]
Distinguishing features: Parent taxon (Globanomalina): Very low trochospiral; 5-6 chambers in final whorl; chamber-shape variable. Aperture interiomarginal, umbilical-extraumbilical, arch with narrow lip. Wall smooth, normally perforate, pustules in some species. This taxon: Test small, 5 chambered, with moderately angular axial periphery, and with an imperforate peripheral margin that is moderately to strongly developed. Aperture a low, umbilical-extraumbilical arch, with a narrow well-defined lip.
NB These concise distinguishing features statements are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus. They are being edited as the site is developed and comments on them are especially welcome.

Aze et al. 2011 summary: Cosmopolitan; based on Olsson et al. (1999) Isotope paleobiologyGlobanomalinacompressa has 8lsO and δ13C similar to Parasubbotinavarianta, S. triloculinoides, and G. ehrenbergi. The species has distinctly more positive δ18O and more negative 8'3C than Morozovella and Praemurica. [Olsson et al. 1999] Aze et al. 2011 ecogroup 3 - Open ocean thermocline. Based on light _13C and relatively heavy _18O. Sources cited by Aze et al. 2011 (appendix S3): Olsson et al. (1999) Phylogenetic relationsThis species shares morphologic similarities with G. archeocompressa in the compressed test and in the bluntly angular imperforate peripheral margin. The upper range of G. archeocompressa has not been firmly established and, consequently, its linkage with G. compressa is, at present, uncertain. We link the two species on the basis of their shared morphologic similarities (Plate 32). [Olsson et al. 1999]
