“…Meanwhile, further taxonomic work has been in progress, with the supplement of associated specimens of different life stages. For example, our recent work established two morphologically similar species of Monodiamesa based on slight but stable variations in diagnostic features and relatively huge genetic divergence (Han et al, 2021 ). A similar case could be found in Diamesa in another study (Han et al, 2022 ).…”

“…Evidence from a growing number of studies shows that the TP is experiencing prominent climate change effects, including glacier retreat (Yao et al, 2019 ), permafrost degradation (Wang et al, 2019 ), lake expansion (Zhang et al, 2019 ), and vegetation alteration (Xiong et al, 2019 ), threatening the habitats of local biota (Liu et al, 2021 ; Zhang et al, 2021 ). Chironomids are often the dominant macroinvertebrates of aquatic ecosystems on the TP (Hamerlík et al, 2010 ; Jiang et al, 2013 ), but we have little knowledge about species richness because few taxonomic works have been conducted there (Han et al, 2021 ; Laug et al, 2019 ; Lin, Chang, et al, 2021 ; Lin, Mo, et al, 2021 ; Makarchenko et al, 2022 ).…”

The main aim of this study was to curate a COI barcode library of Chironomidae from the Tibetan Plateau (TP) as an essential supplement to the public database. Another aim is to evaluate the current status of the public database of Chironomidae in aspects of taxonomic coverage, geographic representation, barcode quality, and efficiency for molecular identification, the Tibetan Plateau, China. In this study, 512 individuals of Chironomidae from the TP were identified based on morphological taxonomy and barcode analysis. The metadata of public records of Chironomidae were downloaded from the BOLD, and the quality of the public barcodes was ranked using the BAGS program. The reliability of the public library for molecular identification was evaluated with the newly curated library using the BLAST method. The newly curated library comprised 159 barcode species of 54 genera, of which 58.4% of species were likely new to science. There were great gaps in the taxonomic coverage and geographic representation in the public database, and only 29.18% of barcodes were identified at the species level. The quality of the public database was of concern, with only 20% of species being determined as concordant between BINs and morphological species. The accuracy of molecular identification using the public database was poor, and about 50% of matched barcodes could be correctly identified at the species level at the identity threshold of 97%. Based on these data, some recommendations are included here for improving barcoding studies on Chironomidae. The species richness of Chironomidae from the TP is much higher than ever recorded. Barcodes from more taxonomic groups and geographic regions are urgently needed to fill the great gap in the current public database of Chironomidae. Users should take caution when public databases are adopted as reference libraries for the taxonomic assignment.

Based on material from the Russian Far East and Eastern Siberia, a revision of the chironomids of the subfamily Prodiamesinae was carried out. A new species Monodiamesa fontinalis sp. nov., is here described, ten species from four genera—Monodiamesa bathyphila Kieffer, M. kamora Makarchenko et Yavorskaya, M. improvisa Makarchenko, M. nitida Kieffer, Odontomesa fulva Kieffer, Prodiamesa levanidovae Makarchenko, Propsilocerus amurensis Makarchenko, P. jacuticus (Zvereva), P. paradoxus Lundström and P. taimyrus Zelentzov are redescribed with varying degrees of completeness. Propsilocerus taimyrus Zelentzov, 2000 is proposed as senior synonym of P. saetheri Wang, Liu et Paasivirta, 2007. DNA barcoding of four species, M. fontinalis sp. nov., M. bathyphila, P. olivacea Meigen and P. akamusi (Tokunaga) was provided. Species delimitation and phylogenetic relationships using COI DNA barcodes confirms the species validity of M. fontinalis sp. nov.

We provide illustrated dichotomous keys for the identification of final (4th) instar larvae of south-east Asian genera of Chironomidae (Diptera), predominantly from aquatic (freshwater and maritime) habitats. The region considered comprises oriental China, Burma, Thailand, Malaysia (west and east), Brunei, Singapore and Indonesia. Eight subfamilies are represented and phylogenetically validated tribes are keyed. Terminal taxa, listed in the sequence used in this guide, comprise 28 genera of Tanypodinae, 71 of Chironominae, 2 of Podonominae, 1 of Buchonomyiinae, 8 of Diamesinae, 2 of Protanypodinae, 5 of Prodiamesinae, 2 of Telmatogetoninae and 61 of Orthocladiinae. The morphology terminology is standard for larval Chironomidae to which users are referred. Illustrations of selected features are provided as photographs with important details labelled. Short summaries of ecology and concise details of selected species and regional / global distribution are provided in brackets under each entry. Some suspect new synonymy is alluded to, but will be addressed formally in more detail elsewhere.
