“…The time-calibrated phylogeny was reconstructed in BEAST v2.6.1 64 based on an external COI evolutionary rate (0.265 ± 0.06% substitutions per site per million years) estimated for the Unionidae 65 . This rate can be considered a reliable estimate as it is largely congruent with the data inferred from a mitogenomic reconstruction 20 . The same multi-locus dataset as for the IQ-TREE and MrBayes phylogenetic analyses (3 codons of COI + 16 S rRNA + 28 S rRNA) was estimated.…”

“…While numerous recent studies reveal that using an integrative approach for freshwater mussel taxonomic research is rather straightforward [4][5][6][7][70][71][72][73] , its application to freshwater gastropods is more difficult due to several shortcomings such as a possible incongruence in a mitochondrial phylogeny 76,77 and often higher DNA barcoding thresholds between species 46,78,79 . At first glance, the differences between these groups can be explained by slower evolutionary rates of freshwater mussels 20,65 compared with those of freshwater gastropods 80 . nomenclatural acts.

While a growing body of modern phylogenetic research reveals that the Western indochina represents a separate biogeographic subregion having a largely endemic freshwater fauna, the boundaries of this subregion are still unclear. We use freshwater mussels (Unionidae) as a model to reconstruct spatial patterns of freshwater biogeographic divides throughout Asia. Here, we present an updated freshwater biogeographic division of mainland Southeast Asia and describe 12 species and 4 genera of freshwater mussels new to science. We show that the Isthmus of Kra represents a significant southern biogeographic barrier between freshwater mussel faunas of the Western indochina and Sundaland subregions, while the Indian and Western Indochina subregions are separated by the Naga Hills, Chin Hills, and Rakhine Yoma mountain ranges. Our findings highlight that the freshwater bivalve fauna of Southeast Asia primarily originated within three evolutionary hotspots (Western Indochina, Sundaland, and east Asian) supplemented by ancient immigrants from the indian Subcontinent. Freshwater mussels (Unionida) are an economically and environmentally important group of aquatic animals having a broad distribution on all continents except Antarctica 1,2. Southeast Asia houses one of the richest endemic faunas of freshwater mussels globally 3-7. Unfortunately, freshwater mussels are among the most endangered animal groups at the global scale, with numerous local extinctions triggered by multiple anthropogenic impacts and climate changes 8-11. Human-mediated degradation of natural habitats, e.g. water pollution, river damming, and irrigation practices, appears to be the most influential factor causing the decline and local extinctions of freshwater mussels 11-13. It was shown that even a prehistoric decline in freshwater mussels corresponds to the early development of agricultural techniques 14. Alien species may represent a significant threat to native freshwater mussel assemblages in Southeast Asia 13 and other regions 15. For example, the tropical lineage of Sinanodonta woodiana (Lea, 1834) is widely spread throughout Malaysia, the Indonesian Archipelago, and the Philippines 16-18 , while the temperate lineage of this taxon was found in Myanmar 19. Recent advances in mitogenomic 20 and multi-locus nuclear 21 phylogenetic modeling reveal that two widespread Southeast Asian subfamilies of the Unionidae, i.e. Pseudodontinae 22 and Rectidentinae 22,23 , represent tribes within the monophyletic Gonideinae. The genus-and species-level taxonomy of freshwater mussels in Southeast Asia is still poorly known 3 , but several integrative studies performed in Myanmar, Thailand, Laos, and Malaysia have recently improved our knowledge about the diversity and biogeographic patterns in the region.

“…It should be noted that a higher diversity of Unionicola mites in Southeast and South Asia was expected initially because this region harbors an ancient, species‐rich, and largely endemic fauna of freshwater bivalves (Bolotov, Kondakov, et al., 2017; Bolotov et al., 2018, 2020; Bolotov, Konopleva, et al., 2019; Bolotov, Vikhrev, et al., 2017; Konopleva et al., 2019; Zieritz et al., 2018).

Freshwater pearl mussels (Bivalvia: Margaritiferidae) are among the most imperiled groups of animals globally. While the parasites and symbionts of the Margaritiferidae are rather poorly known, these mussels were thought to be free of parasitic mites (Acari: Unionicolidae: Unionicola). Here, we report on the discovery of a mite species being associated with the endangered freshwater pearl mussel Gibbosula laosensis (Lea, 1863) from Myanmar. This species, Unionicola (Gibbosulicola) sella subgen. & sp. nov., morphologically resembles mites belonging to the subgenera Coelaturicola and Fulleratax (African and Southeast Asian groups, respectively). Our novel discovery expands the host range of Unionicola mites and reveals that all freshwater mussel families of the order Unionida host these aquatic mites. Our phylogenetic research and available published data reveal that the mussel-associated mite assemblage in Southeast and South Asia contains not less than 17 species and 8 subgenera. Currently, the regional taxonomic richness of this group seems to be largely underestimated. We found that mussel mites from Southeast Asia are narrow host specialists, which are known to occur in a single or a few closely related species belonging to one or two sister genera of freshwater mussels. Finally, our results indicate that mussel mites share generally restricted ranges and that their distribution patterns in Southeast Asia are largely congruent with the boundaries of biogeographic subregions delineated on the basis of phylogenetic studies of freshwater mussels. 614 | CHAPURINA et Al. 1 | INTRODUC TI ON The mantle cavity of freshwater mussels (order Unionida) is a home for a plethora of protists and metazoans, for example, ciliates, leeches, oligochaetes, mites, mayflies, dragonflies, crustaceans, and fishes (Brian &

The Indian black clam Villorita cyprinoides (Family: Cyrenidae), an extractive commercially exploited species with aquaculture importance contributing more than 70% of clam fishery in India, is endemic to the Indian peninsula. Currently, there is very sparse information, especially on the molecular data of Villorita. The present study aims to provide a comprehensive knowledge of mitogenome architecture and assess the phylogenetic status of Cyrenidae. This has resulted in reporting the first complete mitogenome of V. cyprinoides using next-generation sequencing technology. The A+T circular mitogenome was 15,880 bp long, exhibiting 13 protein-coding genes (PCGs) including ATP8 (absent in several bivalves), 22 transfer RNA, and two ribosomal RNA genes residing in the heavy strand in a clockwise orientation and a gene order akin to Corbicula fluminea. The molecular phylogeny inferred from a concatenated multi-gene sequence [14 mitochondrial (12 PCGs, rrnS and rrnL) and two nuclear genes (Histone H3, 18S rRNA)] from 47 representative species of superorder Imparidentia, clustered V. cyprinoides and Cyrenid clams to a single clade supporting the monophyly of Cyrenidae. The subsequent mitochondrial gene order analysis substantiates the close relationship of V. cyprinoides and C. fluminea, analogous to phylogenetic output. The multilocus tree topology calibrated with verified fossil data deciphered the origin and diversification of Cyrenid clams during late Triassic-early Jurassic. The data derived from this study shall contribute remarkably for further insights on cryptic species identification, molecular characterization of bivalve mitogenomes and mitochondrial evolutionary history of genus Villorita. Moreover, complete mitogenome can aid in potential marker development for assessing the genetic health of black clam populations.
