Phytophagy in a Polypedilum (Diptera: Chironomidae) species new to Australia and Japan: taxonomy and expanded Asian distribution

The Australian Biological Resources Study (ABRS) supported collecting in Australia in the 1980s and 90s, with concurrent support for survey of Alligator Rivers Region, Northern Territory, by the Office of Supervising Scientist (via Chris Humphrey). These sources provided a systematic foundation for aquatic entomological studies in remote Australia. In Singapore, collections were made under auspices of PUB-NUS project ‘Chironomid Mass Emergences in Singapore: Monitoring Protocols and Identification of Triggers’ (grant number R-154-000-526-490), and we thank Yuchen Ang (Lee Kong Chian Natural History Museum, Singapore) who kindly provided several images. In China, collections were partially supported by the National Natural Science Foundation of China (grant numbers 41672346 and 31100389).
