Original Description
Type of wall: Normal perforate, spinose, ruber/sacculifer-type wall.
Test morphology: Low trochospiral, subovate and lobulate in outline, chambers globular arranged in 3 whorls, chambers in the last whorl increase regularly and rapidly in size, sutures depressed, straight and radial on both sides; umbilicus open, wide, enclosed by surrounding chambers. Primary aperture an umbilical and distinct circular high arch bordered by a distinct rim. One low to moderately high arched supplementary sutural aperture on the spiral side opposite the primary aperture.

Size: Maximum length of holotype 0.4 mm, maximum width 0.29 mm.

Etymology: Named joli, which means beautiful in French.

Extra details from original publication
DISTINGUISHING FEATURES: 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.

DISCUSSION: Specimens of G. joli were first documented by Spezzaferri (1994) and named G. parawoodi.

PHYLOGENETIC RELATIONSHIPS: Globigerinoides joli probably evolved from G. neoparawoodi n. sp. in Subzone M1b.

STRATIGRAPHIC RANGE: 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.

GEOGRAPHIC DISTRIBUTION: Observed at high latitudes, in the Caribbean Sea, Gulf of Mexico, and at temperate latitudes in the South Atlantic Ocean. Rarely present in the Kerguelen Plateau region.
