Dipylissa bensoni Dumitrica (Figure 15.83). Shell fomed by three systems of
globular caps, in optical section appearing as oval
concentric subhemispheres interconnected by numerous thin
radial beams. Major diameter: 90-120 µm. Ref: Dumitrica (1988).

Octopyle stenozona group? Haeckel (Figure 2L, 2M; 15.80) [=Tetrapyle octacantha].
Shells with two systems of latticed girdles (as described
for the diagnosis of the family, see above) and large
gates (Figure 2L, 2M). Major diameter: 100-250 µm. Ref: Nigrini and Moore
(1979).

Phorticium clevei (Jorgensen) (Figure 2L, 15.82) [=Phorticium pylonium].
Generally resembling O. stenozona, except that
central part is a large structure formed by a series of
spirally arranged chambers. Major axis of shell: 150-200
µm. Ref: Petrushevskaya (1967).

Pylolena armata Haeckel group? (Figure 15.81) [=?Hexapyle spp.]. A
central pyloniid shell surrounded by three centrifugally
radiating girdles whose distal ends join forming a
trigonal outline; this structure may be surrounded by
supplementary growth in the form of a spherical latticed
test. Diameter of fully developed shell: ca. 150 µm.

(1979).
