Aeger tipularius (von Schlotheim, 1822) ( Fig. 1B )

STUDIED MATERIAL. — 4 specimens from Solnhofen ( MNHN.F.A33509, B13442, R 03389; MNHN. GG.2004/57291), 2 specimens from Eichstätt ( MNHN.F.B13440, B13443), 1specimen from unknown locality ( MNHN.GG.2004/8072). Collections A. Milne Edwards, Schwarzchild, Hoffstetter .

COMMENTS

The figured specimen is relatively poorly preserved and is assigned to A. tipularius with doubt because several diagnostic characters have probably remained on the counter plate which is not in the collection. Note that one other species of this genus – A. elegans Münster, 1839 – is known from the Solnhofen Lithographic Limestones but is not present in the Paris collection.
