Size variable. Low trochospiral test with about 4 initially spherical to slightly radially elongate chambers. Embracing loose so that the final chamber is almost completely detached from the previous whorl and the aperture is visible from the lateral and even spiral side (appears as slit); sutures deep. The aperture is developed as a large umbilical arch. Remarks: Differs from Globigerina bulloides in loose embracing, radial elongation of the final chambers, visible aperture (slit) on the spiral side, and in having a thinner and less hispid wall. It also differs from juvenile trochoid Globigerinella siphonifera in having less involute chambers and a less hispid surface of the wall.

Distribution: G. calida appears in most of the climatic areas from equatorial to temperate, but is never abundant in assemblages ( Bylinskaya et al. 2002). This species is rare in our material.
