Species Conoglobigerina jurassica Hofman 1958

Discussion / Comments:

Boudagher-Fadel et al. (1996):
Remarks: C. jurassica was designated as the type and only species of his new genus Woletzina by Fuchs (1973); his drawings are only doubtfully of the same species as that described by Hofman (1958), however. Hofman obtained her specimens from the Bathonian-Early Callovian of SE Crimea (Ukraine). The holotype of this species is lost (personal communication, Dr Tatiana Gorbachik), so we formally designate the paratype figured here (Plate 2.7, Figs 11-13) as the neotype, following article 75 of the ICZN (1985). The neotype is high spired with four chambers in the last whorl and an intraumbilical aperture covered by a bulla (which has at least two accessory apertures). The surface is covered with pseudomuricae which occasionally fuse into very short, disconnected ridges (Plate 2.8, Fig. 3). C. dagestanica Morozova (the type species of Conoglobigerina) also has a bulla (Plate 2.3, Fig. 10) and as noted above in our introductory section ('Origins') bullae are known from the first to last Favusellacea. We have no hesitation in considering Globigerina jurassica to be referable to Conoglobigerina. The specimens drawn by Fuchs (1973) came from the Late Callovian and Early Oxfordian of Poland and the intercameral sutures are more deeply depressed than those of the neotype; their identity is not yet proven.
