Hystrichosphaerina orbifera
From Fensome et al., 2019:
Hystrichosphaerina orbifera (Klement, 1960, p.66–67, pl.9, figs.9–10; pl.10, fig.7) Stover and Evitt, 1978, p.58. Holotype: Klement, 1960, pl.9, fig.9; Stancliffe and Sarjeant, 1990, pl.5, fig.2; Fauconnier and Masure, 2004, pl.48, figs.1–2. Originally Systematophora, subsequently Hystrichosphaerina, thirdly (and now) Hystrichosphaerina?. Questionable assignment: Courtinat in Fauconnier and Masure (2004, p.333–334). Age: middle Oxfordian.
---------------------------------------------------------------------------------------------------
Paratypes: Klement, 1960
Locus typicus: Lõngental 2 Bore
Stratum typicum: Middle Oxfordian
Original diagnosis: Klement, 1960, p. 66: Systematophora orbifera
A species of the genus Systematophora with the, for the type species S. areolata characteristical, oriented arrangement and number of circular areas of the basal process connections. Shell spheroidal to squatly ellipsoidal. Cricularly arranged processes numerous and closely spaced, relatively long, fibrous to firm, often bent in a wavy fashion, distally fused into a characteritical tire shape.
Dimensions: Holotype: shell including processes l:b 100:100 µm, shell without processes l:b 60:58 µm, process length 28 µm.
Affinities: Klement, 1960, p.67: Systematophora orbifera
This species is unambiguously distinguished from from the related S. fasciculigera, by the pronounced spheroidal appearance of the shell, as opposed to the elongate oval outline of the latter species, and by the characteristical, tire-shaped distal coalescence of its processes.
