The present knowledge of the wing‐base morphology of the holometabolous insects is summarized, and the value of these structures for phylogenetic analysis is demonstrated. An autapomorphy of the Holometabola is a locking mechanism composed of a knob on the basalare and a corresponding cavity on the ventral wing‐base. Two synapomorphic hindwing‐base characters support a sister‐group relationship of Coleoptera and Neuropterida. Only few data are available on the wing‐base of the Hymenoptera. An autapomorphy of the taxon is a modification of the wing locking mechanism with reduced size of the basalare and its knob. It is demonstrated that wing‐base characters are helpful for the analysis of the relationships between strepsipteran families. However, characters of the wing‐base support neither a relationship of Strepsiptera and Coleoptera nor of Strepsiptera and Antliophora.
