Remarks. This species is very variable in morphology, with the main shell cylindrical, as in the original drawing of Rüst, or with sides more or less convex. There is also a great variation in the thickness and height of longitudinal costae relative to the transversal or circumferential bands. The latter are almost always of two different types: one higher, representing external expression of intersegmental wall, the other more internal, representing the imperforate central band between the two rows of pores, characteristic of the species, one above and one below. A detailed study of these differences would be probably interesting.
A characteristic of this species, when complete, is that the distal segment has a much smaller diameter than that of the previous chamber forming a neck. The same feature is typical of A. excellens (Tan, 1927) and other Archaeodictyomitridae . For this reason and for having continuous costae, without small nodes at the intersection with the transversal ribs, the specimen attributed to A. apiarium in Dumitrică et al. (1997, p. 38, pl. 7, fig. 7) is herein considered an erroneous determination. It is probably interesting to make a study of the stratigraphic distribution of species with pores arranged not only in longitudinal rows but also in circumferential rows but without nodes at the meeting points of the two type of rows as in Apiaromitra apiarium .
Studied material. Four photographed specimens from OZ 836, 838, 839 of which two included in Fig. 13 View Fig as follow: fig. 13a = PD120-OZ836-R08-26 and fig. 13b = PD120- OZ839-R01-04.
Dimensions. Total length of shell 192-198 µm, maximum diameter 106-124 µm.
Range and occurrence. Mid Callovian-early Oxfordian to late Barremian-early Aptian, cosmopolitan.
