<I>Cladispa</I> Baly: revision, biology and reassignment of the genus to the tribe Spilophorini (Coleoptera: Chrysomelidae: Cassidinae)

Abstract

The genus, Cladispa Baly 1858, is transferred from the tribe Imatidiini (=?Cephaloleiini Chapuis, 1875) to Spilophorini Chapuis, 1875 based on the review of type material, newly collected specimens and molecular phylogenetic analysis. The type species, C.?quadrimaculata Baly, 1858, is redescribed, and two new species, C.?amboroensis sp.n. from Bolivia (Santa Cruz Department) and C.?ecuadorica sp.n. from Ecuador (Pastaza Province), are described and figured. The morphology of C.?amboroensis sp.n. immature stages is broadly consistent with other Spilophorini. Field observations document that both C.?quadrimaculata and C.?amboroensis sp.n. are trophic specialists on Orchideaceae. Keys to Cladispa species and Spilophorini genera are provided. Trophic associations of other Cassidinae and Orchideaceae are discussed.
