I have Borowiec's monographs on Afrotropical Cassidinae, his recent works on Cassidinae of Madagascar, and Grobbelaar, Scholler and Biondi's various publications which are available on ResearchGate, but would like to know if there's any other readily available material on this subject, including Bruchinae, Orsodacnidae and Megalopodidae as well as the other chrysomelid subfamilies?
