A new species of Polypedilum (Cerobregma) (Diptera, Chironomidae) from Oriental China

Abstract

Polypedilum (Cerobregma) huapingensis Liu & Lin, sp. nov. is described and illustrated based on an adult male from Huaping National Nature Reserve, Guangxi, China. A DNA barcode analysis, including the known partial COI sequences of species in the Cerobregma subgenus, was conducted. An updated key to adult males of the subgenus Cerobregma is provided.

New descriptions of the larval and pupal stages of Orthocladius nitidoscutellatus and Psectrocladius nevalis from Xizang, China (Diptera, Chironomidae)

“…Even for the experienced observer, the aquatic larval level and pupal stages are quite similar and almost impossible to be separated, based purely on morphological criteria ( Armitage et al 1995 , Rossaro et al 2022 ). The DNA barcodes corresponding to the 658-bp fragment of the mitochondrial gene cytochrome c oxidase I (COI) has been identified as the core of a global bioidentifcation system at the species level and proved to be useful in the delimitation of non-biting midge species ( Ashe and O'Connor 2012 , Gilka et al 2018 , Liu et al 2021 , Liu et al 2023 , Hebert et al 2003a , Hebert et al 2003b ).…”

New species, a new combination, and DNA barcodes of Parachironomus Lenz, 1921 (Diptera, Chironomidae)

“…The DNA barcodes corresponding to the 658-bp fragment of the mitochondrial gene cytochrome c oxidase I ( COI ) has been identified as the core of a global bio-identification system at the species level ( Hebert et al 2003a , b ). DNA barcodes also proved to be useful in the delimitation of non-biting midge species and has provided important evidence to confirm new species ( Anderson et al 2013 ; Lin et al 2015 , 2021 ; Giłka et al 2018 ; Liu et al 2021 ).…”

New or little-known Boreoheptagyia (Diptera, Chironomidae) in China inferred from morphology and DNA barcodes

“…The DNA barcode corresponding to the 658-bp fragment of the mitochondrial gene cytochrome c oxidase I ( COI ) has been identified as the core of a global bio-identification system at the species level ( Hebert et al 2003a , b ) and has proved to be useful in the delimitation of non-biting midge species and has provided important evidence to confirm new species ( Anderson et al 2013 ; Lin et al 2015 ; Giłka et al 2018 ; Lin et al 2018 ; Song et al 2018 ; Lin et al 2019 ; Liu et al 2021 ).…”
