The systematics of the species of the genus Cystidicola Fischer, 1798, parasites of the swim bladder of physostomous fishes, is revised. Cystidicola farionis Fischer, 1798, C. cristivomeri White, 1941, and C. stigmatura (Leidy, 1886) Ward and Magath, 1917, are considered to be the only valid species in the world. These three species are redescribed. Cystidicola farionis is morphologically indistinguishable from C. stigmatura but the two species are tentatively regarded as distinct until more data on their biology are available. Cystidicola brevicauda Fujita, 1939, and C. mesopi Fujita, 1940, are not members of Cystidicola but they cannot be assigned to any other genus. Cystidicola lepisostei Hunter and Bangham, 1933, is a member of Cystidicola but should be regarded as a species inquirendae. Cystidicola minuta Rhodhain and Vuylsteke, 1934, and C. serratus (Wright, 1879) Railliet, 1916, are regarded as species inquirendae of the genus Rhabdochona. The literature on numerous other species assigned at various times to Cystidicola is reviewed. The host and geographical distribution of the valid members of Cystidicola are reviewed.

Paronchocerca struthionus n.sp. (Onchocercidae: Splendidofilariinae) from the lungs of Struthio camelus L. (Struthionidae) from West Africa has a long, sacculate glandular oesophagus similar to that of Paronchocerca limboonkengi (Hoeppli and Hsü, 1929) n.comb. (= Lemdana limboonkengi), P. bambusicolae, P. tonkinensis, and P. sonini. It can be distinguished by delicate annular cuticular thickenings and, in the male, a preanal hypodermal swelling, three pairs of circumanal papillae, and the length of the right spicule in relation to the length of the tail. Also, lateral, postanal papillae are absent, although inconspicuous subterminal papillae are present. Paronchocerca ciconiarum Peters, 1936, the type species, is redescribed on the basis of material from the pulmonary arteries of Leptoptilus crumeniferus (Lesson) (Ciconiidae) from Uganda. Seventeen valid species are recognized in the genus. Paronchocerca sanguinisardeae, P. choprai, and P. badamii are regarded as species inquirendae and P. alii, as a species incertae sedis. Among larger avian filarioid genera, Paronchocerca appears unique in that each species seems restricted to a single family of birds. Paronchocerca may have become established in early Ornithurae and subsequently persisted in some of the "primitive" birds, as well as having transferred to "modern" groups which now occupy the aquatic adaptive zone originally occupied by the earliest Ornithurae. Paronchocerca apparently has been largely unsuccessful in transferring to other modern groups.

Species Inquirendae

Species of the genus Sadocus Sørensen, 1886 are conspicuous gonyleptids that occur in Chile and Argentina. Here, the genus is revised for the first time and the cladistic analysis based on morphological characters does not corroborate its monophyly unless a phylogenetically unrelated species is excluded (explained further on). A new classification is proposed for the seven species left in the genus and considered valid, of the 13 nominal species previously recognized. Two out of the seven valid species are considered as species inquirendae: Sadocus allermayeri (Mello-Leitão, 1945) [= Carampangue allermayeri Mello-Leitão, 1945] and Sadocus nigronotatus (Mello-Leitão, 1943) [= Carampangue nigronotatum Mello-Leitão, 1943]. The following synonymies are proposed: Sadocus bicornis (Gervais, 1849) [original combination = Gonyleptes bicornis Gervais, 1849] is a junior synonym of Sadocus asperatus (Gervais, 1847) [= Gonyleptes asperatus Gervais, 1847]; Sadocus conspicillatus Roewer, 1913, Sadocus exceptionalis (Mello-Leitão, 1946) [= Araucanoleptes exceptionalis Mello-Leitão, 1946] and Sadocus guttatus Sørensen, 1902 are junior synonyms of the valid name Sadocus polyacanthus (Gervais, 1847) [= Gonyleptes polyacanthus Gervais, 1847]; and Sadocus calcar (Roewer, 1913) [= Lycomedes calcar Roewer, 1913] is a junior synonym of the valid name Gonyleptes horridus Kirby, 1819. Sadocus brasiliensis Soares &amp; Soares, 1949 is not congeneric with Argentinean/Chilean species of the genus according to the cladistic analysis and is here synonymized with Discocyrtus catharinensis (Mello-Leitão, 1923 [= Sadocus catharinensis Mello-Leitão, 1923]).

Rdna Analysis

We sequenced four rDNA regions (ITS-1, ITS-2, 5.8S, and D3 region of 28S) from the parasitic nematode Cystidicola spp. from seven species of fish host and 11 locations in Canada and Finland to elucidate suspected unresolved genetic variation within the genus. A holarctic species, Cystidicola farionis from the swim bladder of Salmonidae and Osmeridae, and a nearctic species, Cystidicola stigmatura from trout and char (Salvelinus spp.), differ in life history, host and geographic range, reproductive strategy, and adult and egg morphology. These nematodes were identical at three rDNA regions (ITS-1, 5.8S, and D3); however, two ITS-2 variants were found that differed at four nucleotide positions: variant I (366 bp) was found in British Columbia populations of C. farionis and in C. stigmatura and variant II (369 bp) was found in Ontario and Finnish populations of C. farionis. These results demonstrate that two species with distinct morphology and biology can have identical rDNA sequences, while two morphologically identical isolates have different ITS-2 sequences. Thus, rDNA spacer regions may not be useful for distinguishing biologically valid species or subspecies in some nematode groups. Although phenotypic variation suggested a third undescribed species of Cystidicola from lake whitefish (Coregonus clupeaformis), rDNA analysis did not provide meaningful evidence of its uniqueness.

Three new nematode species were found in the Angola Basin (south-east Atlantic Ocean) at depths of about 5500 m. Paracyatholaimus diva sp. nov. (Cyatholaimidae) is characterised by outer labial and cephalic setae of about 3–5 μm, multispiral amphidial fovea with six turns in males and four turns in females situated at the level of the dorsal tooth, buccal cavity armoured with only one prominent dorsal tooth, tail consisting of anterior conical and posterior slender cylindrical half portions, and six preanal midventral setose supplementary organs. Paracyatholaimus diva sp. nov. is most similar to Paracyatholaimus rotundus Gerlach, 1964 but differs by slightly longer body (936–1176 μm versus 705 μm), tail shape (with clearly narrowed posterior half versus conical), six versus four supplementary organs of different shape. The genus Paracyatholaimus Micoletzky, 1923 is briefly reviewed. The genus now includes twenty-four valid species. Five species are considered as species inquirendae, mainly because of inadequate type material lacking adult stages and/or incomplete descriptions. A pictorial guide for identification of the valid species of Paracyatholaimus is provided. Pomponema proximamphidum sp. nov. shares subapical position of the amphidial fovea and distinct lateral differentiation of the somatic cuticle with five Pomponema species: P. concinnum Wieser, 1954, P. corniculata Gourbault, 1980, P. mirabile Cobb, 1917, P. multipapillatum Filipjev, 1922 and P. stomachor Wieser, 1954 but differs from them by tail length, longer posterior cylindrical portion of the tail, relative width of the amphidial fovea, position of the ventral pore and lesser number of supplementary organs. Desmodora striatocephala sp. nov. is well characterized by a combination of very large amphidial fovea occupying nearly the entire lateral surface of the cephalic capsule and thickened midventral preanal cuticle with a few supplementary papillae inserted therein in males. D. striatocephala sp. nov. differs from related species D. cuddlesae Inglis, 1963 and to some lesser degree with D. inflexa Wieser, 1954 with shorter body, relative tail length, bigger size of the amphidial fovea and lesser number of supplementary papillae.

The genus Pennella Oken, 1816, mesoparasitic copepods from marine fish and mammals, is reviewed with the objective of determining the validity of members of the genus. Details of the external morphological structures of the adult female are presented. Pennella species are differentiated based on a combination of characters: the type of host parasitized, overall length of the parasite, shape, size and configuration of cephalothoracic papillae, segmentation of the first and second antenna, holdfast horn number, shape and configuration, and structure of the abdominal plumes. A new species of Pennella, Pennella benzi sp. nov., is described from the escolar, Lepidocybium flavobrunneum in the northwest Atlantic. Pennella balaenoptera Koren & Danielssen, 1877 is reported from the harbor porpoise (Phocaena phocaena) in the Bay of Fundy, a new locality record. The validity of 44 species is assessed; nine species (P. balaenoptera Koren & Danielssen, 1877, P. benzi sp. nov., P. diodontis Oken, 1816, P. exocoeti (Holten, 1802), P. filosa Linnaeus, 1758, P. hawaiiensis Kazachenko & Kurochkin, 1974, P. instructa Wilson, 1917, P. makaira Hogans, 1988 and P. sagitta Linnaeus, 1758) are considered substantiated and valid; six species (P. elegans Gnanamuthu, 1957, P. longicauda Gnanamuthu, 1957, P. platycephalus Gnanamuthu, 1957, P. remorae Murray, 1856, P. robusta Gnanamuthu, 1957, and P. selaris Kirtisinghe, 1964) exhibit unique characteristics, but are based on descriptions of single specimens, have not been found since the original reports and are considered as species inquirendae; the remaining species are unsubstantiated and invalid based on inadequate or missing original descriptions, or are designated as synonyms of valid species. A key to the valid species of the genus is provided.

The systematics of the representatives of the genus Rhabdochona, parasitic in fishes of North and Central America, is revised. Rhabdochona cascadilla Wigdor 1918, R. kidderi Pearse 1936, R. decaturensis Gustafson 1949, R. cotti Gustafson 1949, R. ovifilamenta Weller 1938, R. milled Choquette 1951, and R. canadensis sp.nov. are considered as the valid species of this region. The first six species are redescribed and illustrated. The new species, R. canadensis, is described from the cyprinids Hybopsis gracilis (flathead chub; type host), H. plumbea (lake chub), and Rhinichthys cataractae (longnose dace) of Alberta; the latter form is characterized largely by the presence of one or two long filaments at each pole of the eggs, by 14 teeth in the prostom, by the presence of the cuticular spike at the tip of the tail, and by the character of the spicules. The species R. pellucida Gustafson 1949 is regarded as a synonym of R. cascadilla Gustafson 1949, and R. laurentiana Lyster 1940 as a synonym of R. ovifilamenta Weller 1938. Rhabdochona serrata (Wright 1879) Ko and Anderson 1969 is transferred to the genus Cystidicola as species inquirenda. The hosts and geographical distribution of the current members of the genus are reviewed. The paper is supplemented by a key for the identification of the species parasitic in fishes of North and Central America.
