“…The complete mitochondrial genome of E. revolutum (Fröhlich, 1802) Rudolphi, 1809, was 17,030 bp in size; the longest of all the Echinostomatoidea to date sequenced, although the mitogenome of E. paraensei (KT008005) was claimed longer, 20,298 bp, but some of 5,600 nucleotides were only of estimation (Liu et al, 2014;Yang et al, 2015;Le et al, 2016;Ma et al, 2016Ma et al, , 2017Fu et al, 2019;Suleman et al, 2019;Li et al, 2019aLi et al, , 2019b. The length of the mt genome of E. revolutum seemed to be one of the longest among trematodes fully obtained to date, shorter than the estimated, partially sequenced congener E. paraensei, but was slightly longer than other echinostomids, including H. conoideum (Yang et al, 2015), E. miyagawai (Fu et al, 2019;Li et al, 2019b), Ech.…”

Currently, only four of the nine species of the ‘ E. revolutum ’ group, including E. caproni , E. paraensei , E. miyagawai , E. hortense (Saijuntha et al ., 2011 c ), and a few species within the Echinostomata suborder have complete mitochondrial genomes available (Yang et al ., 2015; Fu et al ., 2019; Suleman et al ., 2019; Li et al ., 2019 a , 2019 b ).…”

“…magna, P. ohirai, repetitive units either of long or short sequences and even various quantity within a species, frequently occurred and commonly found (Le et al, 2001(Le et al, , 2016(Le et al, , 2019Liu et al, 2014;Ma et al, 2016Ma et al, , 2017Fu et al, 2019;Li et al, 2019b). Interestingly, none of the repetitive units was found in E. caproni, H. conoideum and T. cymbius (Yang et al, 2015;Li et al, 2019a). The occurrence of repetitive sequences in tandem order in many species certainly is one of the most interesting genomic features, specifying the high-level polymorphism in the NCRs of digenean trematodes.…”

The complete mitochondrial sequence of 17,030 bp was obtained from Echinostoma revolutum and characterized with those of previously reported members of the superfamily Echinostomatoidea, i.e. six echinostomatids, one echinochasmid, five fasciolids, one himasthlid, and two cyclocoelids. Relationship within suborders and between superfamilies, such as Echinostomata, Pronocephalata, Troglotremata, Opisthorchiata, and Xiphiditata, are also considered. It contained 12 protein-coding, two ribosomal RNA, 22 transfer RNA genes and a tandem repetitive consisting non-coding region (NCR). The gene order, one way-positive transcription, the absence of atp8 and the overlapped region by 40 bp between nad4L and nad4 genes were similar as in common trematodes. The NCR located between tRNAGlu (trnE) and cox3 contained 11 long (LRUs) and short repeat units (SRUs) (seven LRUs of 317 bp, four SRUs of 207 bp each), and an internal spacer sequence between LRU7 and SRU4 specifying high-level polymorphism. Special DHU-arm missing tRNAs for Serine were found for both tRNAS1(AGN) and tRNAS2(UCN). Echinostoma revolutum indicated the lowest divergence rate to E. miyagawai and the highest to Tracheophilus cymbius and Echinochasmus japonicus. The usage of ATG/GTG start and TAG/TAA stop codons, the AT composition bias, the negative AT-skewness, and the most for Phe/Leu/Val and the least for Arg/Asn/Asp codons were noted. Topology indicated the monophyletic position of E. revolutum to E. miyagawai. Monophyly of Echinostomatidae and Fasciolidae was clearly solved with respect to Echinochasmidae, Himasthlidae, and Cyclocoelidae which were rendered paraphyletic in the suborder Echinostomata.

Pleurogenoides japonicus (Trematoda: Microphalloidea) is an important parasite in wood frogs with high infection rates and significant ecological, economic, and societal importance. The scarcity of molecular data for these parasites severely limits population genetics and phylogenetic studies. In the present study, for the first time, we determined and described the entire mitochondrial (mt) genome of P. japonicus as the first representative of the family Pleurogenidae. The entire mt genome of P. japonicus was circular, with 15,043 bp (GenBank accession number OR900118), containing 36 genes, comprising 12 protein‐coding genes (cox1–3, nad1–6, nad4L, cytb, and atp6), two ribosomal RNA genes, 22 transfer RNA genes, and two non‐coding regions. There were 23 intergenic spacers, ranging from 2 to 162 bp, and only one 40 bp overlap between nad4L and nad4 genes in the P. japonicus mt genome. The nucleotide composition of P. japonicus mt genome exhibited a strong AT bias with a 63.75% A + T content, while the AT‐ and GC‐skews were − 0.435 and 0.407, respectively. Comparative analysis demonstrated that the P. japonicus mt genome shared the most common characteristics with Microphalloidea trematodes, and the cox1 gene was the longest and most conserved gene in Microphalloidea trematodes. The gene arrangements of Xiphidiata trematodes were of the same order based on protein‐coding genes and rRNA genes, except for tRNA. More than two gene arrangement types exist in Echinostomata and Xiphidiata, and the gene rearrangement events mainly occurred in “trnE‐trnG” and “trnG‐trnE”. Phylogenetic analysis suggested that trematodes of the family Pleurogenidae clustered more with Prosthogonimidae than Eucotylidae. The mt genome data of P. japonicus provide an accurate genetic marker for further studies of Xiphidiata trematodes.
