“…Recent phylogenetic studies have confirmed its validity and its distinctness from the Dilepididae sensu stricto (Mariaux 1998, Hoberg et al 1999. Therefore, the species previously reported as dilepidids by parasitologists, including the present authors (e.g., Scholz 2001, Scholz and Salgado-Maldonado 2001, Scholz et al 2002a, are considered here to belong to the Gryporhynchidae.…”

Abstract. Larvae (metacestodes) of tapeworms of the cyclophyllidean family Gryporhynchidae (previously included in the Dilepididae) occur in different internal organs of fresh-and brackish water fish (110 fish species of 27 families in 12 orders reported), which serve as the second intermediate hosts. , which reported 13 species, suggested that they may be more common than indicated by records in the literature. Although only a few cases of pathogenic influence of larvae on fish hosts have been reported, the veterinary importance of gryporhynchids remains to be assessed on the basis of more detailed studies. The data available indicate a strict host and site specificity of some species whereas others occur in a wide spectrum of fish hosts and are not strictly site-specific. Evaluation of Paradilepis larvae from the liver of salmonid fish from British Columbia, Canada, identified as P. simoni Rausch, 1949by Ching (1982, has shown that they probably belong to two species, P. simoni and P. rugovaginosus Freeman, 1954. Metacestodes of the latter species and those of Cyclustera magna (Baer, 1959) from the intestinal wall of Tilapia zillii (Gervais) from Kenya are reported from fish for the first time.

“…In addition, there is not an explicit concept about the generic composition of the Gryporhynchidae. We accept as sound the opinion of Scholz and Salgado-Maldonado (2001) and Scholz et al (2002), who preferred to consider the "gryporhynchid" genera within the Dilepididae "until the taxonomy of this group of cyclophyllidean tapeworms is resolved" (Scholz and Salgado-Maldonado 2001).…”

Abstract. Arlenelepis harpiprioni gen. et sp. n. (Cyclophyllidea, Dilepididae) is described from the plumbeous ibis Harpiprion caerulescens (Vieillot) (Ciconiiformes, Threskiornithidae) in Province Concepción, Paraguay. This cestode is characterised by a very small body (not exceeding 5 mm in length) consisting of about 30 proglottides, musculo-glandular rostellar apparatus, rostellar hooks arranged in two regular rows, few testes (7-10 in number) situated mostly in a post-ovarian group but one testis pre-ovarian, a large oval cirrus sac reaching antiporal osmoregulatory canals, massive cirrus armed with needle-shaped and thorn-shaped spines, long convoluted vagina, and longitudinally elongate sacciform horseshoe-shaped uterus with deep lobes of the medial uterine wall. The new genus is unique among the family Dilepididae in possessing a rhynchus armed with conical spines.

“…Additional well-fixed material of dilepidids from the AWP should allow exact identifications and perhaps reveal the presence of several additional species. For example, Scholz et al (2002b) found five different dilepidid species in "Phalacrocorax olivaceus" (= the neotropic cormorant, P. brasilianus) in Mexico.…”

Metazoan symbionts, including parasites, infecting the American white pelican (AWP) Pelecanus erythrorhynchos comprise a list of 75 species, 7 of which are new host records. Several new geographic records are also presented, but generally these have a low value because of the migratory nature of the bird. Evidence suggests that some parasites, mostly flies and other arthropods but also nematodes and digeneans, produce detrimental behavioral or pathologic changes in the AWP. Some of the arthropods transmit microbial agents to the pelican. Two digeneans that have the AWP as a definitive host harm and even kill their catfish intermediate host, especially in aquaculture, and another causes abnormalities and mortality in amphibians. Some of the arthropods with low hostspecificity can potentially transmit harmful microbial agents to humans and domestic animals. A few avian bloodflukes, intestinal flukes, and nematodes can potentially cause "swimmers itch," gastroenteritis, and "anisakiasis," respectively, in humans. Because of the life cycles of some helminths, presence of those worms can provide an indication as to the dietary items of a specific pelican individual, where the individual has been, and how long it has been present in an area. Feather mites, lice, and diplostomoid digeneans serve as good parasites to indicate phylogenetic relationships among different pelican species as well as relationships among the Pelecanidae and other families such as the Sulidae.
