Nematodes of freshwater fishes of the Neotropical Region.
This monograph on the nematodes of Neotropical freshwater fishes is similar to the author's previous book which dealt with nematodes of European freshwater fishes [Helminthological Abstracts64, No. 3459]. It is based both on the author's own studies and the published literature and covers all of South and Central America, southern Mexico and the West Indies. The introductory chapters deal with methods of study of fish nematodes, the morphology and taxonomy of fish nematodes, pathogenicity, the biology of nematodes maturing in fishes and the influence of the environment on the species composition of nematodes parasitic in fishes, their geographical distribution and host specificity. The Neotropical fauna of fish nematodes is discussed and the nematodes recorded from freshwater fishes in this region are listed. 137 species and subspecies belonging to 52 genera in 10 superfamilies of adult nematodes have been reported (28 species occur in fishes only as larvae). Of the 52 genera, 27 are endemic to this region. The bulk of the book (pp. 61-413) consists of a detailed systematic review of the nematodes parasitizing Neotropical freshwater fishes as adults (Capillariidae, Cystoopsidae, Pharyngodonidae, Atractidae, Kathlaniidae, Quimperiidae, Cucullanidae, Acanthocheilidae, Anisakidae, Camallanidae, Guyanemidae, Daniconematidae, Philometridae, Gnathostomatidae, Rhabdochonidae, Cystidicolidae, Physalopteridae) and as larvae (Dioctophymatidae, Acanthocheilidae, Anisakidae, Ascarididae, Kathlaniidae, Seuratoidea, Camallanidae, Gnathostomatidae, Spirocercidae, Acuariidae). These sections include keys, diagnoses, descriptions and figures, and information on hosts, localization, geographical distribution and biology. There is a host-parasite checklist and a species index.
