Similar species: This species differs from Neogloboquadrina pachyderma primarily by its larger test, typical rounded shape of the axial periphery and inflated chambers. It is somewhat smaller than both N. asanoi and N. kagaensis, from which it also differs by narrower aperture and much slower rate of chamber expansion in the last whorl. [Kucera & Kennett 2000]
Most likely ancestor: Neogloboquadrina pachyderma - at confidence level 2 (out of 5). Data source: indirectly suggested by Kucera & Kennett 2000.
Geological Range:
Notes: Neogloboquadrina inglei n. sp. is generally present in the early and middle Pleistocene (1.5–0.7 Ma), although it seems to have originated in the Late Pliocene ( 1.9 Ma, Table 3).
Last occurrence (top): within Middle Pleistocene Sub-Epoch (0.13-0.78Ma, top in Ionian stage). Data source: Kucera & Kennett 2000
First occurrence (base): within Late Pliocene Sub-Epoch (2.59-3.60Ma, base in Piacenzian stage). Data source: Kucera & Kennett 2000
