Galerucinae, Latreille 1802 is the second largest subgroup of chrysomelidae. 1837 Chervrolat described the taxon Ootheca, which has originally only one listed species. Nearly 200 years all galerucinae with a "compact" bodyshape, a broad pronotum, a convex dorsum , short antennae and short legs were assigned to Ootheca. When I started a revision of Ootheca, this taxon included 38 species. Comparing morphological characters of the exoskeleton combined with the depiction/description of characteristic structures of the male genitalia allowed a detailed description of the genus Ootheca and its species. After the revision 9 valid species remained in Ootheca, 4 are described to be new, 13 species were transferred to other valid described genera and 10 species remained, because of a lack of unambiguous assignment. The examination of the median lobe additionally enables me to describe three sister taxa: Oothecoides (6 species), Ootibia (5 species ) und Oosagitta (6 species).
