Archaeodictyomitrinae – Petrushevskaya 1981: 192-194. TYPE GENUS. — Archaeodictyomitra Pessagno 1976: 49 [type species by original designation: Archaeodictyomitra squinaboli Pessagno 1976: 50 ].

INCLUDED GENUS (CENOZOIC ONLY). — Dictyomitra Zittel, 1876: 81 (= Dictyomitroma with the same type species; Diplostrobus synonymized by Petrushevskaya & Kozlova 1972: 550; Zifondium synonymized by Petrushevskaya 1981: 196).

DIAGNOSIS. — A multisegmented Nassellaria whose shell is covered by continuously arranged longitudinal costae. One, rarely two, rows of pores are aligned along adjacent longitudinal costae. The pores are open or relict. In some members, relict pores are completely missing in platy grooves between adjacent longitudinal costae.

STRATIGRAPHIC OCCURRENCE. —Early Berriasian-late Middle Eocene.

REMARKS

Illustrations of their cephalic initial spicular system were too rarely published ( Pessagno 1976: pl. 14, fig. 5; Pessagno 1977a: pl. 6, 13: De Wever et al. 2001: fig. 173) to gain an adequate understanding of its organization.
