Abstract
A list of 1298 species and 172 genera of Chrysomelidae from the subfamily Galerucinae (sensu stricto) with the males having at least one form of secondary sexual characteristic (SSC) is presented. The number of species amounts to 24% of the total Galerucinae presently known from all over the world—a very significant amount. The SSCs comprise various types of modified structures found on all parts of the body—head, thorax, and abdomen. They are not variable but species specific. Illustrations from selected 87 species that include 84 images and 15 line drawings showing various types of SSC are provided. The amazing array of SSCs from the Galerucinae offers a large and taxonomically diverse set of data that are not comparable with other subfamilies in the Chrysomelidae and may be useful in phylogenetic analysis of the family.
