Type images:
holotype: N. pelagicaDistinguishing features: monospecific
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.
Morphology: Test large, planispiral, involute, biumbilicate; chambers subglobular to ovate, regularly increasing in size, 5 to 6 in the final whorl; sutures depressed , surface smooth with large and more closely arranged pores, large massive triradiate spines irregularly distributed (PI. 61, Fig. 1) over the surface; aperture interiomarginal, a wide equatorial arch bordered by a thin lip. [Kennett & Srinivasan 1983]
Size: >250µm

In modern oceans a rare, temperate water, species [SCOR WG138]
Geographic distribution: Tropical to temperate. [Kennett & Srinivasan 1983]
Phylogenetic relations: Studies by Bé (1969), Hemleben (1969), and Walker and Vilks (1973) have revealed that H. pelagica is characterized by spines that are consistently triradiate throughout their length. [Kennett & Srinivasan 1983] Molecular Genotypes recognised (data from PFR2 database, June 2017. References: Ujiié & Lipps 2009; Seears et al. 2012; Weiner et al. 2012. The genotypes appear to have broad geographic distribution but to be depth separated, as discussed by Weiner et al. (2012), and summarised in the table.
Most likely ancestor: Globigerinella siphonifera - at confidence level 3 (out of 5). Data source: Kennett & Srinivasan 1983, fig. 26.
Likely descendants: Orcadia riedeli;
Geological Range:
Last occurrence (top): Extant Data source: present in the plankton (SCOR WG138)
First occurrence (base): within N17 zone (5.72-8.58Ma, base in Tortonian stage). Data source: Kennett & Srinivasan 1983
