The structure of spermatheca in the genus Chelymorpha Chevrolat, 1837 (Coleoptera: Chrysomelidae: Cassidinae) and its taxonomic significance
Spermathecae of 42 nominal and three unidentified species of the genus Chelymorpha Chevrolat, 1837 have been studied and figured. The genus, contrary to the most of Cassidinae genera, is characterized by a very diverse structure of spermatheca. Ten morphological groups have been distinguished. The groups are partly correlated with the groups distinguished on the basis of external morphological characters. Based on the structure of spermatheca the following taxonomical changes have been proposed: Chelymorpha alternans Boheman, 1854 is a good species not a synonym of Ch. cribraria (Fabricius, 1775), Ch. reimoseri Spaeth, 1928 is a good species not a synonym of Ch. infecta Boheman, 1854, Ch. andicola Spaeth, 1928 is a distinct species not a subspecies of Ch. constellata (Klug, 1829). Ch. indigesta Boheman, 1854 and Ch. subpunctata Boheman, 1854, Chelymorpha texta Boheman, 1862 and Ch. cribraria (F.), and Ch. bullata Boheman, 1854 and Ch. alternans Boh. represent probably three pairs of polymorphic forms of three species but this problem needs verification by genetic studies.
