Genus Dolocythere Mertens, 1956

Type species: Dolocythere rara Mertens, 1956 ; Borehole Lingen 106, Lower Albian .

Diagnosis. —See Appendix 1.

Remarks. —Described from the Lower Albian of NW Germany, a number of other Cretaceous species have been assigned to the genus ( Deroo 1966; Gründel 1966; Colin 1974; Kubiatowicz 1983; Babinot and Colin 2011) but only two Jurassic species: D. maculosa Bate, 1963 and D. tuberculata Luppold, 2012 from the Bajocian of England and NW Germany respectively, both of which we consider to belong in Minyocythere gen. nov. Dolocythere is therefore a Cretaceous genus. As we have not made a study of Dolocythere , except to determine its recognition from Minyocythere , we are not able to refine its diagnosis or discuss its species, however, in looking at Senckenberg material of D. rara we found material of a new species recognized by Erich Triebel ( SMF collections) and which we describe below as D. amphistiela sp. nov. However, we have analysed the NPC in both D. rara and D. amphistiela in order to (i) compare with Minyocythere species and (ii) with each other.

Stratigraphic and geographic range.—Cretaceous,?Western Europe.
