The discovery of these new terpenoid alkaloids adds to the growing knowledge of millipede defensive secretions and is beginning to provide insights into how these compounds might be biosynthesized and their evolution within millipedes. However, additional chemical investigations into unstudied millipedes belonging to the subterclass Colobognatha are necessary to provide insights into key biosynthetic transformations and to fully understand the evolution of this interesting class of compounds. To date, eleven genera of Platydesmida, and 59 species have not yet to been chemically investigated, and this cohort undoubtedly includes new terpenoid alkaloids yet to be discovered.
