Our results provide convincing support for the monophyly of Scarabaeidae, confirming the debated sister group relationship of dung beetles and phytophagous pleurostict scarabs. Supermatrix-based maximum likelihood and multispecies coalescent phylogenetic analyses strongly imply the subfamily Melolonthinae as currently understood being paraphyletic. We consequently suggest various changes in the systematics of Melolonthinae: Sericinae Kirby, 1837 <i>stat. rest. and sensu n.</i> to include the tribes Ablaberini, Diphucephalini and Sericini, and Sericoidinae Erichson, 1847 <i>stat. rest.</i> and <i>sensu n.</i> to include the tribes Automoliini, Heteronychini, Liparetrini, Maechidiini, Phyllotocini, Scitalini, and Sericoidini. Both subfamilies appear to consistently form a monophyletic sister group to all remaining subfamilies so far included within pleurostict scarabs except Orphninae. Our results represent a major step towards understanding the diversification history of one of the largest angiosperm-associated radiations of beetles.</p>","PeriodicalId":22126,"journal":{"name":"Systematic Entomology","volume":"48 4","pages":"672-686"},"PeriodicalIF":4.8,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/syen.12602","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50153670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
