Taxonomic changes within Imatidiini and Hybosispini (Coleoptera: Chrysomelidae: Cassidinae)

Type specimens of various taxa of Imatidiini and Hybosispini were examined to verify their identity. The following taxonomic changes are proposed based on these comparisons. New combinations: Cephaloleia apertura (Staines, 2013) comb. nov. (from Aslamidium Borowiec, 1984), Cephaloleia jataiensis (Pic, 1923) comb. nov. (from Xenispa Baly, 1859), Pseudimatidium bicoloricornis (Pic, 1926) comb. nov. (from Windsorispa Sekerka, 2014), Xanthispa miniacea (Blanchard, 1843) comb. nov. (from Homalispa Baly, 1859), Xenispa aeneipennis (Baly, 1859) comb. nov. (from Cephaloleia Chevrolat, 1836), Xenispa gilvipes (Uhmann, 1930) comb. nov. (from Cephaloleia), Hybosispa claripes (Pic, 1923) comb. nov. (from Solenispa Weise, 1905), Hybosispa delectabilis (Staines, 1996) comb. nov. (from Cephaloleia), Hybosispa sulciceps (Baly, 1885) comb. nov. (from Cephaloleia), and Hybosispa truncatipennis (Baly, 1869) comb. nov. (from Cephaloleia). New synonyms: Cephaloleia impressa Uhmann, 1930 = Demothispa clermonti Pic, 1934 syn. nov.; Xenispa atra (Pic, 1926) = Cephaloleia cyanea Staines, 1996, syn. nov. Change in status: Cephaloleia fernandoi (Bondar, 1940) stat. restit. is removed from synonymy with C. opaca Baly, 1859. The monotypic genus Serratispa Staines, 2002 assign. nov. is transferred from Sceloenoplini to Imatidiini based on morphological characters. Three species are described: Cephaloleia fouquei sp. nov. from Bolivia and Peru, C. renei sp. nov. from Ecuador, and Xenispa fouquei sp. nov. from Venezuela. Keys to Cephaloleia basalis Weise, 1910 species-group, Venezuelan species of Xenispa Baly, 1859, and species of Hybosispa Weise, 1905 are proposed to simplify identification of respective taxa.
