Abstract

Based on light and scanning electron microscopical studies, one known and one previously undescribed Procamallanus (Spirocamallanus) species (Nematoda: Camallanidae) are described from specimens collected in the intestine of freshwater fishes in the Lower Congo River, Democratic Republic of Congo: P. (S.) daleneae (Boomker 1993) from Synodontis acanthomias Boulenger (Mochokidae, Siluriformes) (new host and geographical records) and P. (S.) parachannae sp. nov. from Parachanna insignis (Sauvage) (Channidae, Perciformes). The new species is most similar to P. (S.) serranochromis Moravec et Van As 2015, a parasite of African cichlids (Serranochromis spp.), differing from it mainly in the absence of any outgrowths on the female tail tip, a distinctly longer (546 μm) right spicule, a different length ratio of both spicules (1:2.6) and in the morphology of fourth-stage larvae. P. (S.) daleneae, a specific parasite of squeakers (Synodontis spp.), is redescribed; in contrast to the original description, the number of postanal papillae was found to be identical (6 pairs) with that of other related species.
