Genus BULBOPHRAGMIUM

BULBOPHRAGMIUM Maync, 1952
 
 
Type species: Haplophragmium aequale Roemer of Reuss, 1860 (*2581), p. 218 (non Spirolina aequalis Roemer, 1841) = Bulbophragmium aequale Maync, 1952: see Loeblich and Tappan, 1954, *1888, p. 33; ICZN Art. 11 (i), 70 (c); (syn.: Lituola westfalica Bartenstein, 1952, *146, p. 323): OD.
Bulbophragmium Maync, 1952 (*2067), p. 46.
Test elongate, early chambers streptospirally enrolled, later uncoiled and rectilinear, sutures straight and depressed, interior with short and thick radiating vertical partitions; wall coarsely agglutinated, thick; aperture termi­nal and cribrate. U. Cretaceous (Campanian); Europe.
 
Remarks: A "neotype" was designated for "Haplophragmium aequale Reuss" (non Spirolina aequalis Roemer) by Bartenstein (1952, *146, pl. 5, figs. la-c), renamed as Lituola westfalica. As Maync (1952, *2067) stated Haplophragmium aequale Reuss to be the type species of Bulbophragmium, and cited Reuss's original figures, the same specimen becomes the neotype for Bulbophragmium aequale Maync.
The type species is still poorly known since neither Maync nor Bartenstein illustrated sections of it. However, the section originally illustrated by Reuss and later by both Maync and Bartenstein shows a thick wall with about eight short and thick radial partitions. Details of the wall are unknown, and it may be alveolar. The genus is more closely related to Labvrinthidoma than to Haplophragmium.
