Integrative taxonomy reveals hidden cestode diversity in Pimelodus catfishes in the Neotropics

Abstract: Proteocephalid tapeworms are the dominant group of endoparasites in siluriform catfishes in South America, but their interrelationships and actual diversity remain poorly understood. Molecular prospecting of proteocephalids found in pimelodid and other catfishes, especially in Pimelodus spp., along with thorough morphological evaluation, revealed high species diversity of these parasites. Using newly obtained sequences of the partial large subunit nuclear ribosomal RNA (lsrDNA) and complete mitochondrial cytoc… Show more

“…nov., despite the presence of robust external, internal, and molecular differences (Figs. 1,2,3,4,8,9). Thus, the periodic-like mapping of the polychromatic variants in combination with statistical analysis of the diagnostic characters is an important tool in addition to the molecular phylogenetic analysis.…”

“…The application of molecular tools combined with classical morphological analysis has significantly improved our understanding of the diversity, phylogenetic relationships, host-associations, and distribution of cestode parasites in vertebrates around the globe (Caira & Jensen, 2017). Using this integrative approach, Alves et al (2021a) erected the genus Pseudoendorchis Alves, de Chambrier, Luque & Scholz, 2021 (Cestoda: Onchoproteocephalidea) to accommodate four species, namely P. auchenipteri (de Chambrier & Vaucher, 1999) (type species) from Auchenipterus osteomystax (Miranda-Ribeiro) (Auchenipteridae, type host) in Paraguay and Pimelodus maculatus Lacepe `de (Pimelodidae) in Brazil, both from the Parana ´River basin (PRB); P. cristata Alves, de Chambrier, Luque & Scholz, 2021 from Pimelodella cristata (Mu ¨ller & Troschel) (Heptapteridae) in the Amazon River basin (ARB) in Brazil; P. felipei Alves, de Chambrier, Luque & Scholz, 2021 from Pimelodus fur (Lu ¨tken) (Pimelodidae) in Brazil (Miranda River, PRB); and P. souzalimae Alves, de Chambrier, Luque & Scholz, 2021 from Pimelodus maculatus in Brazil (Parana ´and Miranda Rivers, both PRB). In addition, three putative new species were recognised based on molecular data (lsrDNA and COI sequences), but they were not formally described due to either poor quality or incompleteness of the material available (Alves et al, 2021a).…”
