Family DIPYLISSIDAE Dumitrica, 1988 n. stat.

Dipylissinae Dumitrica, 1988: 188-190 ; 1989: 261. — De Wever et al. 2001: 151. — Afanasieva et al. 2005: S286. — Afanasieva & Amon 2006: 129.

TYPE GENUS. — Dipylissa Dumitrica, 1988: 190 [type species by monotypy: Dipylissa bensoni Dumitrica, 1988: 190 ].

INCLUDED GENUS. — Dipylissa Dumitrica, 1988: 190 .

DIAGNOSIS. — A Larcospiroidea with systems of two single-capped latticed girdles that are arranged face to face along the polar axis and rotated at 90° of each another. The first system includes a microsphere and a wide apically-opened antapical cap.

STRATIGRAPHIC OCCURRENCE. — late Late Miocene-Holocene.

REMARKS

As the hierarchical consistency in the family level is improved to concord with the ranking of other spumellarian, this subfamily is raised to the family level. The internal skeletal structure of Dipylissa was illustrated ( Dumitrica 1988: pl. 6, figs 1-15; 1989: pl. 12, figs 18-24). Undescribed Dipylissa morphospecies are found in plankton samples (study in progress).
