A Review of the Newly Recorded Genus Proceroplatus Edwards, 1925 (Diptera: Keroplatidae) in China with Two New Species, and Its Characterization and Phylogenetic Implication of Mitogenomes

Proceroplatus (Keroplatidae: Keroplatinae) is a distinct keroplatid group comprising 39 described species. These species are found worldwide, but none had previously been reported in China prior to this study. In this paper, Proceroplatus is recorded for the first time from China, along with two new species: P. dapanshanussp. n. and P. biemarginatussp. n., which were collected from the southern region. Here, a worldwide distribution map of this genus is presented by species, including the new ones. Images and detailed morphological descriptions are provided for each new species, accompanied by molecular identification based on the standard mitochondrial cytochrome oxidase subunit I (COI) gene. To clarify the mitogenomic characteristics of Proceroplatus, the well-assembled and annotated mitogenome of P. dapanshanus was obtained and described in detail. The comparative analyses and phylogenetic tree indicate that the mitogenomic evolution of keroplatids is relatively conserved and influenced not only by mutation pressure but also by natural selection and other factors.
