“…Pairwise comparison of both the ITS and cox1 sequences in the dataset and the phylogenetic relationship of our material with C. strumosum showed each of them to be a different species. The present molecular analysis revealed that the genetic variation in the ITS and cox1 regions shows useful genetic markers for identifying and discriminating acanthocephalan parasites (Rosas-Valdez et al 2020;Chaudhary et al 2020;Ru et al 2022), especially for the analysis of closely related species. Our phylogenetic results from the ITS region showed that our Caspian Sea population of C. neostrumosum is clearly differentiated from the closely related species, C. strumosum and C. magdaleni, with strong support that aligns with Amin et al (2011).…”

An isolated population of 700 specimens initially described as Corynosoma strumosum (Rudolphi, 1802) Lühe, 1904 and currently reassigned to Corynosoma neostrumosum n. sp. was collected from one young male Caspian seal, Pusa caspica (Gmelin) in the southern land-locked Caspian Sea in April 2009. Collected worms were morphologically unique compared with those reported by other observers in open waters, especially in shape and distribution of proboscis hooks and trunk spines, dorso-ventral differences in proboscis hooks and their organization, the baldness of anterior proboscis, consistently smaller size of trunk and testes, larger eggs, the rough egg topography, epidermal micropores, and variations in the female gonopore. Molecular data from the internal transcribed spacer region of rDNA and the mitochondrial cox1 gene was also provided to supplement the morphological study of the new species.

“…The order Polymorphida is a large group of Acanthocephala, containing over 370 nominal species mainly parasitic in birds and mammals, rarely in reptiles (Amin, 2013; Zhao et al ., 2020; Ru et al ., 2022). According to the traditional classification, Polymorphida was divided into 3 families (Centrorhynchidae, Polymorphidae, and Plagiorhynchidae), including 24 genera (Amin, 2013).…”

“…The acanthocephalan specimens of B. nipponicum and C. villosum were collected from the intestine of subadult northern fur seals Callorhinus ursinus (Linnaeus) (Mammalia: Carnivora) and Hippoglossus stenolepis (Schmidt) (Pleuronectiformes: Pleuronectidae) in St. Paul Island, Alaska, USA, fixed and stored in 70% ethanol. The specimens were identified as B. nipponicum and C. villosum based on morphological features according to previous studies (Van Cleave, 1953; Margolis, 1956; Ru et al ., 2022). Voucher specimens were deposited in the College of Life Sciences, Hebei Normal University, Hebei Province, China ( B. nipponicum : HBNU–A-2022M002L; C. villosum : HBNU–A-2022F003L).…”

Acanthocephalans of the order Polymorphida mainly parasitic in birds and mammals, are of veterinary, medical and economic importance. However, the evolutionary relationships of its 3 families (Centrorhynchidae, Polymorphidae and Plagiorhynchidae) remain under debate. Additionally, some species of Polymorphida (i.e. Bolbosoma spp. and Corynosoma spp.) are recognized as zoonotic parasites, associated with human acanthocephaliasis, but the mitochondrial genomes for representatives of Bolbosoma and Corynosoma have not been reported so far. In the present study, the complete mitochondrial genomes B. nipponicum and C. villosum (Acanthocephala: Polymorphidae) are reported for the first time, which are 14 296 and 14 241 bp in length, respectively, and both contain 36 genes [including 12 PCGs, 22 tRNA genes and 2 rRNA genes] and 2 non-coding regions (NCR1 and NCR2). The gene arrangement of some tRNAs in the mitogenomes of B. nipponicum and C. villosum differs from that found in all other acanthocephalans, except Polymorphus minutus. Phylogenetic results based on concatenated amino acid (AA) sequences of the 12 protein-coding genes (PCGs) strongly supported that the family Polymorphidae is a sister to the Centrorhynchidae rather than the Plagiorhynchidae, and also confirmed the sister relationship of the genera Bolbosoma and Corynosoma in the Polymorphidae based on the mitogenomic data for the first time. Our present findings further clarified the phylogenetic relationships of the 3 families Plagiorhynchidae, Centrorhynchidae and Polymorphidae, enriched the mitogenome data of the phylum Acanthocephala (especially the order Polymorphida), and provided the resource of genetic data for diagnosing these 2 pathogenic parasites of human acanthocephaliasis.
