1. We investigated the distribution of chironomid taxa in urban wetlands in the greater Melbourne area, Australia, to test if their distribution was influenced by sediment pollution and other environmental variables. 2. For identification of the Chironomidae, DNA markers generated via polymerase chain reaction-restriction fragment length polymorphism of cytochrome c oxidase sub unit I (COI) were validated against morphology and reference specimens for more than 5000 chironomids representing over 80 species. DNA-based identification generally concurred with morphological separation, but also indicated the existence of cryptic diversity in some genera. 3. Non-metric multidimensional scaling (N..
