“…Though differing by the number of the taxa included, the phylogenetic trees based on 28S rRNA gene (Neov et al, 2019), 18S rRNA gene and the combined tree have similar topologies. Although partial (D1-D3) large (28S) and complete small (18S) nuclear ribosomal genes form part of a tandem array (Hillis & Dixon, 1991), together and in combination with partial COI, this combination of genes has been shown to demonstrate utility in resolving intra-and intergeneric relationships among cestode orders (e.g.…”

“…The combined analysed involved all taxa originally sequenced for the purposes of the present study (table 1) as well as three additional taxa (Dilepis undula, Hymenolepis diminuta and Rodentolepis microstoma). These were totally 15 taxa, for which sequences with sufficient coverage for the three genes were availablethat is, 18S rRNA and COI (tables 2 and 3) and 28S rRNA (Neov et al, 2019). Phylogenetic analyses were performed using Bayesian inference with MrBayes, version 3.2.7 (Ronquist et al, 2012).…”

“…The pioneer study by Haukisalmi et al (2010) proposed the first phylogenetic hypothesis for the relationships among mammalian hymenolepidids, which was based on sequencing partial (D1-D3) 28S ribosomal RNA (rRNA) gene; it revealed the presence of four major phyletic lineages in the group, which were named 'Ditestolepis clade', 'Arostrilepis clade', 'Hymenolepis clade' and 'Rodentolepis clade'. Subsequently, Neov et al (2019) analysed the phylogenetic relationships of this group based on partial (D1-D3) 28S rRNA gene of 12 selected taxa as well as sequences obtained by Haukisalmi et al (2010) and other authors (Greiman & Tkach, 2012;Greiman et al, 2013;Tkach et al, 2013Tkach et al, , 2018Binkienė et al, 2015Binkienė et al, , 2019Makarikov et al, 2015Makarikov et al, , 2018, comprising a total of 40 taxa. This study confirmed the same major clades but also added more details on the evolution of the host-parasite associations and the main morphological characteristics of the members of this group.…”

“…The aim of the present study is to test the hypothesis for the phylogenetic relationships among mammalian hymenolepidids (based on the 28S rRNA gene) by examining the phylogeny of the group on the basis of cytochrome c oxidase I (COI) and 18S rRNA genes as well as a combined analysis using these two genes and the previously published sequences of 28S rRNA genes (Neov et al ., 2019).…”

The aim of the study is to test a hypothesis for the phylogenetic relationships among mammalian hymenolepidid tapeworms, based on partial (D1–D3) nuclear 28S ribosomal RNA (rRNA) genes, by estimating new molecular phylogenies for the group based on partial mitochondrial cytochrome c oxidase I (COI) and nuclear 18S rRNA genes, as well as a combined analysis using all three genes. New sequences of COI and 18S rRNA genes were obtained for Coronacanthus integrus, C. magnihamatus, C. omissus, C. vassilevi, Ditestolepis diaphana, Lineolepis scutigera, Spasskylepis ovaluteri, Staphylocystis tiara, S. furcata, S. uncinata, Vaucherilepis trichophorus and Neoskrjabinolepis sp. The phylogenetic analyses confirmed the major clades identified by Haukisalmi et al. (Zoologica Scripta 39: 631–641, 2010): Ditestolepis clade, Hymenolepis clade, Rodentolepis clade and Arostrilepis clade. While the Ditestolepis clade is associated with soricids, the structure of the other three clades suggests multiple evolutionary events of host switching between shrews and rodents. Two of the present analyses (18S rRNA and COI genes) show that the basal relationships of the four mammalian clades are branching at the same polytomy with several hymenolepidids from birds (both terrestrial and aquatic). This may indicate a rapid radiation of the group, with multiple events of colonizations of mammalian hosts by avian parasites.
