Original description (Zevenboom 1995):
Impagidinium siciliense Zevenboom and Santarelli sp.nov. (manuscript name) (Plave V, 2, 5, 8)
Manuscript holotype: Sample Cp 3668/2, EF (F34), plate V, 4, 6, 8
Etymology: in reference to the isle of Sicily, type region of the new species.
Type locality: Giamoia section, Sicily, South Italy
Type stratum: Upper Miocene

Diagnosis: A small subspherical speciesof impagidinium with perforated septa. The margins of the septa are denticulate

Dimensions: Height 38 (40) 43 µm; Width 38 )39) 42 µm; Septa 4 (5) 6 µm; N = 25

Description: A small subspherical species of Impagidinium characterized by perforate septae with denticulate margins. The endophragm is smooth, the periphragm microgranulate. In the parasulcal area the ps paraplate is always reflected and in some cases also the lps paraplate is indicated. The lps paraplte is very small.

Discussion: Impagidinium siciliense differs from the morphologically similar I sphaericum Wall, 1967, in possessing denticulate perforate septae.
Occurrence: Italy (this study)
Total stratigraphic range: Middle Miocene (this study, see Fig. 5
