paratype: G. joli
paratype: G. joliDistinguishing features:
Parent taxon (Globigerinoides): Supplementary apertures, with ruber/sacculifer-type spinose wall texture
This taxon: Like G. neoparawoodi but with more lobate outline and a thick rim bordering the aperture.
Globigerinoides joli strongly differs from the holotype of G. parawoodi (Keller, 1981) here placed in synonymy with G. italicus Mosna and Vercesi by having a more lobate profile, a more elongated outline, and a higher arched and circular umbilical aperture bordered by a rim, rather than the oblique and drop-like (higher than wide arch) aperture of G. italicus. It differs from G. altiaperturus by the somewhat lower arched primary and supplementary apertures and by the more lobate profile. It differs from G. neoparawoodi n. sp. by the more lobate outline and the thick rim bordering the aperture. It differs from T. quadrilobatus and T. primordius by the ruber/sacculifer-type wall, by having a higher arched primary aperture bordered by a thick rim, which is lacking in T. quadrilobatus and slightly tends to the peripheral margin in T. primordius.

Geological Range:
Notes: Globigerinoides joli ranges from Subzone M1b to Zone M4? Spezzaferri (1994). Additional studies are needed to confirm the presence of this species in younger Miocene sediments. [Spezzaferri et al. 2018]
Last occurrence (top): within M4 zone (16.38-17.54Ma, top in Burdigalian stage). Data source: Spezzaferri et al. 2018
First occurrence (base): within M1b subzone (21.12-22.44Ma, base in Aquitanian stage). Data source: Spezzaferri et al. 2018
