Six species of cestodes are recorded from 21 herring gulls in New Brunswick, Canada. Five of these are redescribed while the other, representing a new species, is described for the first time. Three of these species are recorded from Canada for the first time and one species represents a new host record.

AbstractA new strigeid digenean, Strigea inflecta sp. nov., is described from the small intestine of the Red-legged Seriema, Cariama cristata (L.) (Gruiformes, Cariamidae) from Formosa Province, Argentina. This species is characterized by having a body plump, a cup-shaped forebody with a large opening, a sacciform hindbody, without a neck region and strongly curved dorsally, a poorly delimited copulatory bursa, wider than longer, a shallow and asymmetrical genital atrium, and a genital cone well delimited from body parenchyma, strongly muscular, inclined towards the surface ventral of the body. Another digenean species collected from Red-legged Seriema, Brachylaima yupanquii Freitas, Kohn et Ibáñez, 1967 (Brachylaimidae) is described with the addition of new morphological characters and morphometrical data. This species is reported for the first time in Argentina and C. cristata represents a new host record.

ABSTRACTA new species of polystomatid monogenean,Eupolystoma anterorchissp. n. is described from the urinary bladder and kidneys ofBufo pardalisfrom the Cape Peninsula, Republic of South Africa. It is distinguished from otherEupolystomaspecies, and from all other species except one within the Polystomatidae, by the anterior pre-ovarian extension of a large proportion of the testis follicles. This and other morphological characteristics are incorporated into an amended generic diagnosis.The morphology ofE. alluaudifromBufo regularisin West Africa is also described. The known range of this species is enlarged with new geographical records in the Cameroun and Ethiopia, and a new host record fromNectophrynoides malcolmi.Material from each area shows that the eggs ofEupolystomaspp. complete developmentin uteroand that all developmental stages of the parasite occur side by side within the same host individual. This represents a significant evolutionary departure from the pattern of transmission typical ofPolystomain most of the other anuran hosts.

AbstractParagordius is a genus of Gordiida with a worldwide distribution, but with a scarce specific diversity. Sixteen species of the genus Paragordius have been described so far. In many cases, as with the other genera of Gordiida, the original descriptions of the species are insufficient due to the limitations of the techniques employed. In this work the holotypes of P. minusculus and P. esavianus are redescribed by scanning electron microscopy (SEM), a new species of Paragordius is described, the distribution for P. esavianus and P. varius is enlarged and a new host record of P. esavianus is presented.

Summary The parasitic infections of 125 anurans belonging to 13 taxa from Ase community in Delta State in the Niger Delta of Nigeria was investigated. An overall prevalence of 77.6% was recorded and the 32 parasites recovered included one pentastomid, four cestode, four monogenean, ten digenean and thirteen nematode taxa. Among the anurans examined, Ptychadena bibroni harboured the highest number of parasites. Most of the parasites encountered were adults but some occurred as larvae, which either used the amphibians as intermediate or transport hosts. Hylarana galamensis is considered an accidental host for the larval brachylaimid trematode and, a new host record for the larval strigeiod while Polystoma galamensis infection of this frog is made for the first time outside the savannah biotope. Hymenochirus sp. is a new host record for Progonimodiscus colubrifer. Two Foleyellides spp., one occurring in Hyperolius concolor, Afrixalus fulvovitattus and Sclerophys regularis and the other in H. galamensis occur in the study area.

Rhipidocotyle pentagonum (Ozaki, 1924) is reported for the first time in South America parasitizing Auxis thazard and in a new host Katsuwonus pelamis. Tergestia laticollis (Rudolphi, 1819) is reported for the first time in South America and in Thunnus albacares, representing a new host record. Copiatestes filiferus (Leuckart, in Sars, 1885) is recorded for the first time in Brazil and in Thunnus albacares, another new host record. Tetrochetus coryphaenae (Yamaguti, 1934) is presented for the first time in Brazil parasitizing Thunnus albacares.

Thelastomatidae is one of the largest families parasitizing insects, within the order Oxyurida. In this work we reported parasitism in nymphs and adults of Neocurtilla claraziana by two different thelastomatid species as a part of a field survey on agricultural pests. Nymphs and adults of this insect were isolated from grasslands of Buenos Aires State, Argentina using a tensio-active solution. The nematode species Gryllophila skrjabini Sergiev, 1923 and Cephalobellus magalhaesi Schwenk, 1926 are briefly described and measurements are given. Both nematodes are reported for the first time in Argentina with C. magalhaesi being the second isolation of this species in the world. Neocurtilla clarziana is a new host record for G. skrjabini.

AbstractThree nematode species of Cithariniella (Pharyngodonidae), C. citharini, C. khalili, and C. gonzalesi, were recorded from the recta of squeaker (Mochokidae: Siluriformes) and citharinid (Citharinidae: Characiformes) fishes from Senegal, West Africa. Morphological characteristics obtained by scanning electron microscopy (form of oral aperture and cephalic papillae, presence of lateral alae, distribution and form of cloacal papillae, simple or paired papillae on tail of males, eggs with numerous long filaments on each pole in females) correspond well to the generic diagnosis and represent species differences. The shape and size of the cephalic papillae and lips were identified as a new determination feature. C. gonzalesi is reported for the first time from Senegal and its host, Paradistichodus dimidiatus, represents a new host record. A tentative simple key for differentiating C. citharini, C. khalili, C. gonzalesi and C. petterae is provided based upon these results.

Steringovermes notacanthi, a new genus and species of fellodistomine digenean, is described from the deep-sea spiny eel Notacanthus bonaparte from below 1,000m depth in the north eastern Atlantic. It differs from other related genera in the unique combination of a V-shaped excretory vesicle, multilobate, mainly post-testicular ovary and extensive vitelline fields extending into both the foreand hindbody. In addition, the fellodistomine Olssonium turneri Bray & Gibson, 1980 is reported for the first time from a fish not of the genus Alepocephalus, namely the alepocephalid Narcetes stomias.

Apophallus brevis Ransom, 1920, collected from the intestine of a ringbilled gull (Larus delawarensis), has been identified as the definitive stage of metacercariae found encysted in flesh of yellow perch (Perca flavescens). These metacercariae and (or) cysts have been described under various names: Distomum sp. larv. of Cooper, 1915; "sand-grain grub," Tetracotyle sp. of Hunter, 1942; and Apophallus itascensis Warren, 1953. In addition, an aberrant postmetacercarial form was described as Apophallus americanus by Van Cleave and Mueller (1932). Known definitive hosts are ringbilled and herring gulls (L. argentatus), the latter constituting a new host record for this worm species.Apophallus imperator Lyster, 1940, the etiological agent of "black-spot disease" in brook trout (Salvelinus fontinalis), synonymized by Miller (1941) with Apophallus brevis, is here recognized as a distinct species. Except for shape and length of pharynx, adult flukes of these two species are difficult to differentiate unless extremes of characters are present in observed specimens as ranges of measurements of morphological features have considerable overlap. Though these organisms are nearly identical morphologically during the adult stage, they have the following major distinctions: host specificity, sexual development, location and type of cyst and body size as metacercariae, and maturation time and longevity in definitive hosts.

AbstractTwo species of Kalicephalus Molin, 1861 were collected from the intestine of Varanus salvator (Laurenti, 1768) from Guangdong Wildlife Rescue Centre, Guangzhou, Guangdong Province, China. Kalicephalus (Kalicephalus) guangdongensis sp. nov. is similar to K. (K.) schadi Ogden, 1966 and K. (K.) schadi fotedari Kalia et Nayital, 1989 in having extremely long spicules, but differs from the latter in the relative length of spicules (spicules longer than the total body length instead of spicules almost three quarters of the total body length). Kalicephalus (Kalicephalus) schadi fotedari Kalia et Nayital, 1989 is reported for the first time in China, and Varanus salvator is a new host record.
