A revised description of Synodontella zambezensis Douëllou et Chishawa, 1995 (Monogenea: Ancyrocephalidae) from the gills of Synodontis zambezensis (Siluriformes: Mochokidae) from South Africa

Abstract

SummaryThis study supplements the original description of Synodontella zambezensis Douëllou et Chishawa, 1995 and represents a new geographical record for this parasite from Synodontis zambezensis from South Africa. The revision is based on morphometric characteristics and molecular data. Characterisation of LSU, partial SSU and ITS1 rDNA represents a fi rst record of DNA sequencing for Synodontella species.

“…Despite both sequences being published by some of the same authors the sequence of U. tenuis was omitted in the study on C. paranapanemense (Zago et al, 2021) unlike those of other species of Urocleidoides Mizelle and Price, 1964 letting us doubt its reliability. Species of Calceostoma Van Beneden, 1858, Neocalceostoma Tripathi, 1959, Neotetraonchus Bravo-Hollis, 1968, and Synodontella Dossou & Euzet, 1993 were omitted as the available DNA sequences (Justine et al, 2002;Hayward et al, 2007;Raphahlelo et al, 2016;Mendoza-Franco et al, 2018) were unusually short or non-alignable. For genera with more than three species with available sequences, we only included two to three specimens to reflect the major clades of the genus based on previous phylogenetic studies including for Anacanthorus Nagibina, 1970, Characidotrema Mendoza-Franco, Reina & Torchin, 2009, Chauhanellus Bychowsky & Nagibina, 1968, Cichlidogyrus Paperna, 1960, Dactylogyrus Diesing, 1850, Euryhaliotrema Kritsky & Boeger, 2002, Haliotrematoides Kritsky, Yang & Sun, 2009, Hamatopeduncularia Yamaguti, 1953, Heteropriapulus Kritsky, 2007, Lethrinitrema Lim & Justine, 2011, Ligophorus Euzet & Suriano, 1977, Metahaliotrema Yamaguti, 1953, Nanayella Acosta, Mendoza-Palmero, da Silva & Scholz, 2019, Quadriacanthus Paperna, 1961, Scutogyrus Pariselle & Euzet, 1995, Thaparocleidus Jain, 1952, and Urocleidoides Mizelle & Price, 1964(Wu et al, 2007, 2008Blasco-Costa et al, 2012;Sun et al, 2014;García-Vásquez et al, 2015;Acosta et al, 2017Acosta et al, , 2019…”

“…3, Table 1): Adult worms 624 (609-778) long, 113 (81-167) large at the level of ovary. Pharynx circular 39 (34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45). Dorsal bar with rectangular center with two lateral expansions, one stick-shaped median process posteriorly directed with two filaments at its end.…”
