Procamallanus (Spirocamallanus) huacraensis infecting the catfish Trichomycterus spegazzinii from Escoipe River, Salta province (Argentina), is redescribed and genetically characterised for the first time, based on three genetic markers (nuclear 18S and 28S rRNA; cytochrome c oxidase subunit I [cox1] mtDNA). The phylogeny of Camallanidae was also discussed. Morphological evaluation of P. (S.) huacraensis using light and scanning electron microscopy revealed the previously undescribed features… 
An integrative approach assesses the intraspecific variations of Procamallanus (Spirocamallanus) inopinatus, a common parasite in Neotropical freshwater fishes, and the phylogenetic patterns of Camallanidae
Host, environment and geographic aspects seem to be related to some lineages within Camallanidae; however, their real phylogenetic meanings are still unclear.
Parasites of Cambeva davisi (Siluriformes: Trichomycteridae) from the Cascavel stream, Neotropical area
The presence of the nymphs of S. oxycephala did not result in harmful histological changes or a significant inflammatory process in infected organs, and new records of distribution and host-parasite relationships reported here enrich knowledge of the parasitic fauna of freshwater fish from the Neotropical region.
Deep in the systematics of Camallanidae (Nematoda): using integrative taxonomy to better understand the phylogeny and consistency of diagnostic traits.
Although traits of buccal capsule, male tail, habitat, host and biogeographic were highly consistent, intrinsic patterns varied according to different taxa assemblages, which supported the partition of Batrachocamallanus as synonym of Procamallanus and Spirocam allanus.
Incipient genetic divergence or cryptic speciation? Procamallanus (Nematoda) in freshwater fishes (Astyanax)
The results showed that P. (S.) neocaballeroi is experiencing an incipient divergence although the morphological study of lineages shows no conspicuous differences, and genetic lineages of the nematode exhibit a clearer pattern of host species association and geographical distribution.
A checklist of the parasitic nematodes of freshwater fishes from Argentina
The knowledge about parasitic nematodes from Argentinian freshwater fishes is far from complete, since some hydrological basin mainly in Pampean and Andean Cuyan regions and some host families remain unexplored in terms of nematode parasite detection.


Redescription and first genetic characterisation of Procamallanus (Spirocamallanus) macaensis Vicente & Santos, 1972 (Nematoda: Camallanidae), including re-evaluation of the species of Procamallanus (Spirocamallanus) from marine fishes off Brazil
Phylogenies inferred using sequences of the SSU rDNA from camallanids mostly generated weakly supported clades; however, Camallanus Railliet & Henry, 1915 and Procamallanus Baylis, 1923 do not seem to be monophyletic.
A New Species of Camallanidae from Ageneiosus ucayalensis (Pisces: Siluriformes) from Pará State, Brazil
The new species differs from the most closely related species by the presence of 8–10 cuticular spiral thickenings in the buccal capsule of males and 9–13 in the females, 8 pairs of male clocal papillae (3 pre- and 5 post-cloacal, respectively), and only males bearing 2 minute, spike-like projections at the posterior end.
Procamallanus pacificus differs markedly from all congeners from fish hosts in possessing a greater number (4–9) of caudal mucrons in the female and by other morphological features, and might become a serious pathogen of cultured eels in the region of the South Pacific.
Phylogenetic relationships of some spirurine nematodes (Nematoda: Chromadorea: Rhabditida: Spirurina) parasitic in fishes inferred from SSU rRNA gene sequences.
The results indicate geographical isolation has not been the cause of speciation in this parasite group and no coevolution with fish hosts is apparent, and the placement of Cucullanidae at the base of the suborder Spirurina is supported.
Procamallanus (Spirocamallanus) spp. (Nematoda: Camallanidae) from fishes of the Okavango River, Botswana, including P. (S.) serranochromis n. sp. parasitic in Serranochromis spp. (Cichlidae)
All findings of the two previously known species represent new host records and a key to the species of Procamallanus (Spirocam allanus) parasitising fishes of continental Africa is provided.
Two nematodes, Dentinema trichomycteri n. g., n. sp. (Cosmocercidae) and Procamallanus chimusensis Freitas & Ibáñez, 1968 (Camallanidae), from catfishes Trichomycterus spp. (Pisces) in Colombia
Light and scanning electron microscopical examinations of nematode samples collected from the stomachs and intestines of catfishes Trichomycterus spp. (Trichomycteridae, Siluriformes) from three
Two new species of nematode parasites, Cucullanus epinepheli sp. n. (Cucullanidae) and Procamallanus (Spirocamallanus) sinespinis sp. n. (Camallanidae), from marine serranid and haemulid fishes off New Caledonia.
Based on light and scanning electron microscopical studies, two new species of parasitic nematodes are described from marine perciform fishes off New Caledonia: Cucullanus epinepheli sp. n.
Camallanus Railliet et Henry, 1915 (Nematoda, Camallanidae) from Australian freshwater turtles with descriptions of two new species and molecular differentiation of known taxa
Two new species of Camallanus are described from Australian freshwater turtles and sequence comparison of more than 500 base pairs at the 5′ end of the nuclear 28S rDNA gene confirms the status of C. sprenti and C. beveridgei as new species.
Molecular Characteristics of Camallanus Spp. (Spirurida: Camallanidae) in Fishes from China Based On its rDNA Sequences
The internal transcribed spacers of ribosomal DNA (ITS rDNA) sequences of these nematodes were determined and confirmed 2 valid species of Camallanus in China, i.e., C. cotti and C. hypophthalmichthys.
Spirocamallanus monotaxis is redescribed from Monotaxis grandoculis (Lethrinidae) and reported from 10 other species of coral reef associated fishes from both the Society Islands and the Tuamotu
