| Abstract: | The defensive secretions of two tropical species of millipedes (the spirostreptid Telodeinopus aoutii and a species of Harpagophoridae) contain a complex mixture of closely related benzoquinones and hydroquinones. The major
compounds are toluquinone and 2-methoxy-3-methylbenzoquinone, accompanied by the minor components, 2,3-dimethoxybenzoquinone
and toluhydroquinone. Because of the large size and the geographic separation of the test animals a common defensive strategy
of tropical, large millipedes against predation by vertebrates is assumed.
