    DEAR EDITOR,

    A new gobionine species,Microphysogobio oujiangensissp.nov., was collected from the Oujiang River Basin during field work in Lishui City, Zhejiang Province in 2021.The new species can be well distinguished from its congeners by the combination of the following characteristics: mouth shallow arc-shaped, width of cutting edge on upper jaw equal to half mouth width, central portion of anterior papillae arranged in one row with 6-10 well-developed papillae of equal size,medial pad on lower lip bisected into two squircle-shaped pads, and grooved; midventral region completely scaled and thorax scaleless, lateral line scales 36-38, pre-dorsal scales 8-10; barbel length 26.7%-31.4% of head length; eye diameter 30.9%-36.9% of head length, interorbital width 21.3%-27.6% of head length; posterior chamber of air-bladder weak, length smaller than half eye diameter.Bayesian inference and maximum-likelihood phylogenetic analyses based on the cytbgene sequence and species delineation also supported the specimens as a distinct species, sister toM.brevirostris(Günther, 1868).

    East Asia has the most diverse gobionine fish in the world,andMicrophysogobiois one of the most species-rich genera in the subfamily Gobioninae.There are 30 valid species in this genus, 23 of which are distributed in China (Sun et al., 2021).Among the Chinese species, nine are found in independent coastal rivers in southeast China (e.g., Zhejiang, Fujian,Guangdong, and Taiwan provinces), includingM.brevirostris,M.fukiensis(Nichols, 1926),M.bicolor(Nichols, 1930),M.tafangensis(Wang, 1835),M.alticorpus(B?n?rescu &Nalbant, 1968),M.microstomusYue, 1995,M.xianyouensisHuang, Chen & Shao, 2016,M.zhangiHuang, Zhao, Chen &Shao, 2017, andM.luhensisHuang, Chen, Zhao & Shao,2018 (Huang et al., 2016, 2018).Thus, southeast China is a hotspot of species diversity of the genusMicrophysogobio.

    Microphysogobiospecies usually inhabit the upper and middle streams of a river system.Unlike gobionine genera from lower reaches, such asHemibarbusandSaurogobio,Microphysogobiospecies are diverse, with well-developed lip papillae and a small-sized air-bladder, indicating strong adaptability to benthic life (Yue, 1998).The horny sheaths of the cutting margins on their upper and lower jaws enable them to scrape algae from pebbles and stones in slow-flowing shallow waters (Sun et al., 2021).Given their microhabitat characteristics and benthic habitat preferences,Microphysogobiospecies may be easily separated by common barriers, such as mountains and lower reaches of streams.Thus, the coastal rivers in southeast China provide ideal habitats and speciation environments forMicrophysogobio.

    In 2021, during field collection in Zhejiang Province,southeast China, we discovered a population ofMicrophysogobiothat was morphologically and genetically distinct from all known congeners, which we describe herein as a new species within the genus.

    Specimens were collected by hand nets, fish traps, or from local markets.Detailed information on the compared specimens is provided in the Comparative Materials(Supplementary Materials).Specimens used for morphological study were fixed in 10% formalin solution for three days,followed by 70% ethanol for long-term preservation at the Institute of Zoology, Chinese Academy of Sciences, Beijing(ASIZB).Specimens used for molecular studies were preserved in 95% ethanol.Other examined materials were deposited at ASIZB, Biodiversity Research Museum,Biodiversity Research Center, Academia Sinica, Taipei(ASIZP), and Taiwan Ocean University, Keelung (NTOUP).

    Morphological comparisons and measurements followed Sun et al.(2021) and Zhao & Sun (2021).The meristic values in parentheses after counts indicate frequency and asterisks indicate holotype count.Molecular study was based on the cytbsequence.DNA was extracted from the pectoral fin on the right side of the fish.cytbwas amplified using the primers in Huang et al.(2016).Sequencing results were assembled using SeqMan II, and other sequences were acquired from the NCBI database.Individual codes, locality information,haplotype details, and GenBank accession numbers are given in Supplementary Table S1.In total, 37 cytbsequences fromMicrophysogobiospecies were used in this study, withPseudogobio guilinensisused as an outgroup.Nucleotide sequence alignment was verified using MEGA v6.0 (Tamura et al., 2013) with ClustalW.ModelFinder (Kalyaanamoorthy et al., 2017) was used to select the best-fit model using Bayesian information criterion (BIC).The BI phylogenies were inferred using MrBayes v3.2.6 (Ronquist et al., 2012) under the GTR+F+G4 model (two parallel runs, 1 000 000 generations),with the initial 25% of sampled data discarded as burn-in.ML phylogenetic analysis was performed using MEGA 6.0 under the TN93+G model (1 000 bootstrap replications).In addition,two independent methods, i.e., assemble species by automatic partitioning (ASAP) and Poisson tree process(PTP), which rely on different operational criteria, were applied to infer molecular species delineation forMicrophysogobio(Kapli et al., 2017; Puillandre et al., 2021).Aligned sequences were uploaded to the ASAP online server using the Jukes-Cantor (JC69) model (https://bioinfo.mnhn.fr/abi/public/asap/)and the rooted phylogenetic trees (BI and ML), without an outgroup, were uploaded to the PTP online server(http://species.h-its.org/ptp/).The evolutionary divergence of sequence pairs between and within groups was estimated using the Kimura 2-parameter model (Kimura, 1980).

    Distribution:Microphysogobio oujiangensissp.nov.is currently known only from the Oujiang River, a coastal river located in Zhejiang Province, China (Figure 1K).

    Habitat and biology:Microphysogobio oujiangensissp.nov.inhabits the clear water of rivers with sandy riverbeds containing gravel and pebbles (Figure 1L).Based on our observations and collection,Microphysogobio oujiangensissp.nov.usually inhabits deeper water areas during the day,then moves to shallower areas at nightfall.Based on the horny sheaths on its upper and lower jaws,Microphysogobio oujiangensissp.nov.usually feeds by scraping algae from pebbles.Coexisting species includeAcrossocheilus wenchowensisWang, 1935,Distoechodon tumirostrisPeters,1881,Sarcocheilichthys parvusNichols, 1930,Leptobotia brachycephalaGuo & Zhang, 2021,Cobitisspp.,Vanmanenia stenosoma(Boulenger, 1901), andTachysurus ondon(Shaw,1930).

    Etymology:The name of the new species,oujiangensis, is derived from the name of the locality river basin, Oujiang (甌江).Its common name in Chinese is “甌江小鰾鮈”.

    Genetic comparisons:A total of 36 mitochondrial cytbhaplotypes from 37Microphysogobioindividuals were included in this analysis.Molecular phylogenetic analysis indicated that the new species was sister toMicrophysogobio brevirostris(Figure 1M).Based on the K2P model, the interspecific genetic distance betweenMicrophysogobio oujiangensissp.nov.and its closest congenerM.brevirostrisfor cytbwas 5.2%, while the intraspecific genetic distances ofMicrophysogobio oujiangensissp.nov.andM.brevirostriswere much lower (0.7% and 1.5%, respectively).ASAP analysis recognized 11 molecular operational taxonomic units(MOTUs) among the 15 species, while the PTP method for the BI tree supported 15 MOTUs, with posterior probabilities of 0.57, 0.36, 0.74, 0.97, 0.90, 1.00, 0.96, 0.93, 1.00, 1.00, 0.96,0.97, 0.82*, 0.71, and 0.68, respectively (* refers to node ofMicrophysogobio oujiangensissp.nov.).The mPTP analysis for the ML tree supported 14 MOTUs, with posterior probabilities of 0.95, 0.92, 1.00, 0.81, 0.89, 0.50, 0.88, 1.00,1.00, 0.84, 0.88, 0.81*, 0.64, and 0.59 respectively(Supplementary Figure S2).Both methods supportedMicrophysogobio oujiangensissp.nov.as a distinct taxon.The genetic evidence also supportedMicrophysogobio oujiangensissp.nov.as a possible distinct species based on currently available sequences.The BI and ML phylogenetic trees showed different tree topologies, with Bayesian posterior probabilities and bootstrap values.The genetic distances based on cytbamong the 15 species ofMicrophysogobioare given in Supplementary Table S3.The ML tree is provided in Supplementary Figure S2.

    Remarks:Among the 30 validMicrophysogobiospecies,Microphysogobio oujiangensissp.nov.can be easily distinguished fromM.chinssuensis(Nichols, 1926),M.yaluensis(Mori, 1928),M.kiatingensis(Wu, 1930),M.hsinglungshanensisMori, 1934,M.amurensis(Taranetz,1937),M.anudariniHolcík & Pivnicka, 1969,M.linghensisXie, 1986,M.liaohensis(Qin, 1987),M.rapidusChae & Yang,1999,M.wulonghensisXing, Zhao, Tang & Zhang, 2011, andM.nudiventrisJiang, Gao & Zhang, 2012 by having completely scaled mid-ventral region (vs.incompletely scaled mid-ventral region (Xing et al., 2011)).

    Compared to those species with completely scaled midventral regions, the new species can also be distinguished fromM.tungtingensis(Nichols, 1926),M.bicolor,M.tafangensis, andM.zhangiby having six branched anal-fin rays (vs.five) and wider cutting edge on upper jaw (equal or larger than half mouth width vs.smaller than half mouth width).

    Microphysogobiooujiangensissp.nov.can be distinguished fromM.fukiensis,M.kachekensis(Oshima,1926),M.elongatus(Yao & Yang, 1977),M.yunnanensis(Yao & Yang, 1977),M.vietnamicaMai, 1978,M.pseudoelongatusZhao & Zhang, 2001, andM.luhensisby having wider horny sheathed cutting edge on upper jaw (equal or larger than half mouth width vs.smaller than half mouth width, Figure 1E, H).Microphysogobio oujiangensissp.nov.differs fromM.microstomusandM.jeoniKim & Yang, 1999 by having well-developed lip papillae (vs.undeveloped lip papillae).In addition, the new species differs fromM.nikolskii(Dao & Mai, 1959) by having 36-38 lateral line scales (vs.43(Huang et al., 2018)).

    The new species is similar toM.longidorsalisMori, 1935,M.koreensisMori, 1935, andM.alticorpusregarding squamation patterns on midventral region, width of cutting edge on upper jaw, and number of anal-fin rays.However,Microphysogobio oujiangensissp.nov.differs fromM.longidorsalisby having a different dorsal fin shape (distal margin slightly concave vs.distal margin strongly convex).Microphysogobio oujiangensissp.nov.differs fromM.koreensisby number of lateral line scales (36-38 vs.39-41 (Kim & Yang, 1999)).The new species can be distinguished fromM.alticorpusby having 36-38 (average 37) lateral line scales (vs.35-36 (average36)), two scales below lateral line (vs.three), deeper concavity on top of snout before nostrils (vs.smooth or shallow concavity), and different lip papillae pattern (medal pad disconnected from two lateral lobes vs.medal pad connected to two lateral lobes on anterior side of medal pad to posterior side of lateral lobes by elongated papillae).

    The new species is very similar toM.brevirostrisandM.xianyouensis, with all sharing a similar lip papillae pattern,equal number of scales below lateral line, and apparent concavity on top of snout before nostrils.However, the new species can be distinguished fromM.xianyouensisby having 10-11 (average 11) branched pectoral-fin rays (vs.11-12(average 12)), interorbital width 21.3%-27.6% of HL (vs.28.4%-30.2% of HL), and barbel length 81.3%-90.4% of eye diameter (vs.66.6%-72.6% of eye diameter).The new species can also be distinguished fromM.brevirostrisby having 36-38 (average 37) lateral line scales (vs.38-39(average 38)), 8-10 (average 9) pre-dorsal scales (vs.11),interorbital width 21.3%-27.6% of HL (vs.29.9%-32.6% of HL), and eye diameter 30.9%-36.9% of HL (vs.25.3%-30.9%of HL).Detailed morphological data are shown in Supplementary Table S2.

    Based on phylogenetic analysis, the new species formed a monophyletic lineage withM.brevirostris, in agreement with their morphological similarities.The sister linage containingM.xianyouensis,M.longidorsalis, andM.koreensisalso showed some morphological similarities with theMicrophysogobio oujiangensissp.nov.-M.brevirostrislinage.The new species is currently known only from the Oujiang River Basin, whereasM.brevirostrisis only found in independent rivers north of the Miaoli Plateau on Taiwan Island (Chang et al., 2016),M.xianyouensisis only distributed in the Mulanxi River Basin,andM.longidorsalisandM.koreensisare only distributed in the South Korean Peninsula.These five species indicate a potential relationship among mainland China, Taiwan Island,and the Korean Peninsula.For example, although the distribution of the new species exhibits no overlap withM.brevirostrisorM.xianyouensis, the distribution patterns of these three species suggest a close historic connection between the river basins, especially between the Tamsui River Basin on Taiwan Island and the coastal rivers in Zhejiang and Fujian.In fact, land bridges between the Asian continent and Taiwan emerged three or four times during the Pliocene and Pleistocene epochs, and many terrestrial species could have migrated from the mainland to the island during these glaciations as a result of lowered sea levels (Huang et al.,1995; Yu, 1995).Previous studies have shown that freshwater fish species such asSqualidus argentatus,Hemibarbus labeo,Sinibrama macrops, andOpsariichthys evolans, which are distributed on the Miaoli Plateau along the Tamsui River in Taiwan, have a close relationship with congeners found in the coastal rivers of Zhejiang (Hsu et al., 2005; Lin et al., 2010;Yang et al., 2012).Two north and south routes connecting Taiwan and mainland China have also been suggested in previous studies based on freshwater fish fauna similarity(Oshima, 1923; Tzeng, 1986), andM.brevirostrisis considered a north-originated species (Chang et al., 2016).The discovery ofMicrophysogobio oujiangensissp.nov.provides additional evidence to support this view.
