1988 Siphocampium (?) davidi Schaaf – Thurow, p. 408, pl. 7, fig. 25.

Material. A single specimen in sample OZ826.

Remarks. This specimen, very similar to the specimen illustrated by Thurow (1988) from what he considered Hauterivian-lower Aptian, differs from S. elegans n. sp. by not having a conical apical horn, by having the thorax much broader and the abdomen with distal end a little irregular.

Fam. Xithomitridae O’Dogherty, Gorican & Gawlick 2017

Type genus. Xitomitra O’Dogherty, Gorican & Gawlick 2017
