Deflandrea bicavata
Deflandrea bicavata (Jain and Millepied, 1973) Herngreen, 1975
Now Senegalinium. Originally (and now) Senegalinium, subsequently Deflandrea. See also Alterbia (combination illegitimate).
Lentin and Williams, 1977, retained this species in Senegalinium Jain and Millepied, 1973.
Holotype: Jain and Millepied, 1973, pl.1, figs.1-3
Locus typicus: Borehole CM-1, Senegal, northwest Africa
Stratum typicum: Campanian-Maastrichtian
Original diagnosis: Jain and Millepied, 1973, p.23: Senegalinium bicavatum
Shell ovoid, non tabulate, bicavate; periphragm thin, zone of contact around equator large extending into one apical and two antapical horns leaving behind two or three pericoel areas, surface serrate or smooth. Endophragm thick, dark, granulose with localized verrucose thickening along margins in pericoel areas. Archaeopyle intercalary, penta to hexagonal, below the apical horn. Transverse furrow indistinct, indication of longitudinal furrow present.
Original description: Jain and Millepied, 1973, p.23: Senegalinium bicavatum
Epitract and hypotract nearly equal, epitract conical in outline, apical horn broader than long with apical pore; hypotract rounded antapically with two antapical horns of unequal size, acuminate. Intercalary archaeopyle lies up to or below the capsule margin.
Size: Holotype: overall length 100 Ám, overall width 65 Ám, endocyst length 64 Ám, endocyst breadth 65 Ám, length of apical horn 7 Ám, breadth of apical horn 13 Ám, length of antapical horn 17 Ám, breadth of antapical horn 20 Ám. Range: overall length 90-100 Ám, overall breadth 55-70 Ám, endocyst length 60-70 Ám, endocyst breadth 55-70 Ám, length of apical horn 6-22 Ám, width of apical horn 13-30 Ám, length of antapical horn 6-16 Ám, breadth of antapical horn 10-20 Ám.
