Type species: Candorbulina universa Jedlitschka, 1934 (syn.: Orbulina suturalis Brönni­mann, 1951 (*372), _p. 135): OD(M). Candorbulina Jedlitschka 1933 (*1602). p. 20.

Test spherical, early stage trochospirally enrolled as in Globigerina. final chamber much larger, spherical, and enveloping the umbili­cal side of the trochospiral part, trochospiral coil flush with the surface or protruding some-what above that of the spherical chamber, sutures flush to slightly depressed: wall cal­careous, perforate. surface with elongate spines. attached by a boss to the surface, spines may be cylindrical and circular in section or may become triangular or triradiate distally: aper­ture interiomarginal and umbilical in the early trochospiral stage, replaced in the final stage by a series of large sutural supplementary openings at the contact of the early whorl and final chamber, and may have additional areal supplementary openings. M. Miocene (Helvetian to Tortonian): cosmopolitan .

 

Remarks: When regarded as congeneric with Orbulina, Jedlitschka's species from the Miocene of Czechoslovakia becomes a jun­ior subjective synonym of Orbulina universa d'Orbigny, and Brönnimann, 1951 (*372) included C. universa Jedhtschka(non Orbulina universa d'Orbigny) in the synonymy of Orbulina suturalis Brönnimann. However, he se­lected a holotype from the Trinidad specimens. Candorbulina differs from Orbulina in hav­ing an incomplete globular final chamber attached to the umbilical side of the early trochospiral stage that commonly projects above the surface. whereas in Orbulina the early trochospiral stage is isolated within the completely spherical final chamber but held in place by the elongate spines that project through the outer chamber wall. As the two genera are here regarded as distinct, Jedlitschka^'s name is reinstated. The rare living "Orbulina suturalis^" described by Vilks and Walker (1974, *3293, p. 7) as having spines of simple rounded section probably is unrelated to the Miocene Candorbulina but may be a developmental stage of Globigerinoides (Desai and Banner. 1985, (*948, p. 87).
