From Fensome et al., 2019:
Rigaudella aemula ssp. integra (Cookson and Eisenack, 1958, p.47, pl.7, figs.6–7) Below, 1982b, p.147. Holotype: Cookson and Eisenack, 1958, pl.7, fig.6; Fensome et al., 1995, fig.1 — p.1565; Fauconnier and Masure, 2004, pl.68, figs.8–9. Originally Cannosphaeropsis aemula subsp. integra, subsequently Adnatosphaeridium aemulum subsp. integrum, thirdly (and now) Rigaudella aemula subsp. integra. Age: Late Jurassic.

---------------------------------------------------------------------------------------------------

Locus typicus: Carnarvon Basin, W Australia
Stratum typicum: Late Jurassic

Original diagnosis: Cookson and Eisenack, 1958, p.47 Cannosphaeropsis aemulum ssp. integrum
Shell sphaeroidal with a number of hollow, funnel-like processes the wall of which are, for the most part, entire or only slightly perforated. The "funnels" are connected by short delicate threads.
Dimensions: Overall diameter 95-128 µm, processes 24-38 µm.

Affinities:
Cookson and Eisenack, 1958, p.47: Cannosphaeropsis aemulum ssp. integrum
The subspecies integrum is readily distinghuishable from the typicul examples of C. aemula by the rather shorter, broader and more entire processes.
