“…The life-cycle of P. grandivesicularis was completed by Kostadinova & Chipev (1992). Cercariae from naturally infected Planorbis planorbis (L.) in Lake Durankulak (Bulgarian Black Sea coast) were used to infect aquarium-reared small fish (Lebistes reticulatus, Puntius tetrazona tetrazona, P. pentazona pentazona, P. nigrofasciatus, Carassius auratus auratus and Xiphophorus helleri), which served as experimental second intermediate hosts.…”

Petasiger Dietz, 1909 is revised, and a key to and lists of the records and hosts of the 18 recognised species are presented. The recognised species are: P. exaeretus Dietz, 1909, P. australis Johnston & Angel, 1941, P. combesi Zamparo, Overstreet & Brooks, 2005, P. floridus Premvati, 1968, P. grandivesicularis Ishii, 1935, P. islandicus Kostadinova & Skirnisson, 2007, P. johnstoni n. sp., P. megacanthus (Kotlán, 1922), P. minutissimus Gogate, 1934, P. neocomense Fuhrmann, 1927, P. nitidus Linton, 1928, P. novemdecim Lutz, 1928, P. oschmarini Kostadinova & Gibson, 1998, P. phalacrocoracis (Yamaguti, 1939), P. pseudoneocomense Bravo-Hollis, 1969, P. pungens (Linstow, 1894), P. soochowensis Ku, Chiu, Li & Zhu, 1977 and P. variospinosus (Odhner, 1910). Seven of these species are redescribed on the basis of type and newly collected material. P. laricola Ku, Chiu, Li & Zhu, 1977, Echinochasmus fotedari Chishti & Mir, 1989 and P. neocomense of Canković, Kazić & Milka (1983) are considered synonyms of P. pungens; P. longicirratus Ku, 1938, P. skrjabini Bashkirova, 1941 and P. nitidus of Chen et al. (1985) synonyms of P. neocomense; P. caribbensis Nassi, 1980 a synonym of P. novemdecim; and P. tientsinensis Ku, Chiu, Li & Zhu, 1977 a synonym of P. exaeretus. P. johnstoni n. sp. is described from Tachybaptus ruficollis novaehollandiae in Australia. It is readily distinguished from the most closely-related P. grandivesicularis Ishii, 1935 and P. australis Johnston & Angel, 1941 by the smaller size of the body and angle collar spines and differences in most other metrical characters. Species attributed to Petasiger which are here considered species inquirendae are: P. antigonus Nigam, 1944 sp. inq., P. chandleri Abdel-Malek, 1952 sp. inq., P. jubilarum Elperina in Skrjabin, Petrov & Bashkirova, 1947 sp. inq., P. nicolli Pande, 1939 sp. inq. and P. spasskyi Oshmarin in Skrjabin, Petrov & Bashkirova, 1947 sp. inq.; and Echinoparyphium inopinatum (Baer, 1959) n. comb. is a species previously attributed to Petasiger.

“…Obviously, further work is needed on both the life-his tory and adult morphology of Petasiger spp. Never theless, at the present time, adult morphology is all we have in most cases to provide criteria for erecting new species within the genus Petasiger, for the identifica tion of Palaearctic material and for solving taxonomic problems, since life-history data for the Palaearctic species are almost non-existent (Karmanova, 1971 ;Kostadinova & Chipev, 1992). Unfortunately, current knowledge of the morphology of the Palaearctic spe cies of Petasiger does not permit reliable species iden tification, since existing morphometric data for the three species under study exhibit overlapping ranges for all characters with the exception of the cirrus-sac length (see Fuhrmann, 1927;Ishii, 1935;Yamaguti, 1939;Mendheim, 1940;in Skrjabin & Bashkirova, 1956;Prudhoe, 1945;Skrjabin & Bashkirova, 1956;Macko, 1959;Odening, 1962;Odening, 1965;Cankovic et al, 1983;Borgarenko, 1984;Chen et al, 1985;Iskova, 1985).…”

“…In fact, recovery of Petasiger species from experimental definitive hosts has proved to be a difficult task, and several other authors have been unsuccessful in recovering parasites from different laboratory models (canaries, chicks, rats, snakes, ducks, pigeons, cats, mice, and rats). Previous studies have only been able to obtain these parasites from canaries, which were often observed to have a low prevalence and intensity of infection (BEAVER, 1939;ABDEL-MALEK, 1953;NASSI, 1980;OSTROWSKI DE NÚÑEZ, 1982;KOSTADINOVA;CHIPEV, 1992;KOSTADINOVA, 1997). It is expected that the advent of molecular approaches, such as those recently used to elucidate the life cycle of Petasiger islandicus Kostadinova andSkírnisson, 2007 (GEORGIEVA et al, 2012), will promote an understanding of the association between larvae and adults of different species of Petasiger, including South American species.…”

“…After emerging from the mollusks, cercariae display a fishing lure swimming behavior and are ingested by fish, in which they encyst in the oral cavity. Upon ingestion of the fish by fish-eating birds, the metacercariae develop into adult parasites in the small intestines of these hosts (BEAVER, 1939;ABDEL-MALEK, 1952, 1953KOSTADINOVA;CHIPEV, 1992;GEORGIEVA et al, 2012).…”

Species of Petasiger Dietz, 1909 are intestinal trematodes of aquatic birds. Despite the diversity of described species in Europe and North America, only two South American species are known and no species have been previously reported in birds from Brazil. During a study of helminths recovered from the Least Grebe, Tachybaptus dominicus (Linnaeus, 1766), from the state of Minas Gerais, Brazil, adult trematodes identified as Petasiger novemdecim Lutz, 1928 were found. The prevalence of infection was 55% (5/9), and the mean intensity of infection was 8 (1-32) parasites. Additionally, Biomphalaria straminea (Dunker, 1848) and Biomphalaria tenagophila (d'Orbigny, 1835) obtained from aquatic collections in the same state were found to harbor two species of echinostome cercariae of the Magnacauda group. These cercariae developed into metacercariae in experimentally infected Poecilia reticulata Peters, 1859. Attempts to obtain adult parasites in vertebrate host models (mice, chickens, ducks and canaries) were unsuccessful. The present study is the first report of Petasiger in Brazilian birds and the first morphological description of larvae of these parasites in Brazilian mollusks. Taxonomic aspects related to South American species of Petasiger are discussed. It is suggested that, based on significant morphological differences observed in larval stages (i.e., larval dimensions) and adult parasites (i.e., disposition of the testes), Petasiger caribbensis Nassi, 1980 should be reconsidered as a distinct species from P. novemdecim.Keywords: Trematodes, grebes, mollusks, cercariae, Petasiger, Brazil. ResumoEspécies do gênero Petasiger Dietz, 1909 são trematódeos intestinais de aves aquáticas. Apesar da diversidade de espécies descritas na Europa e América do Norte, somente duas espécies são conhecidas na América do Sul, e nenhuma espécie reportada previamente em aves do Brasil. Durante o estudo de helmintos recuperados de Mergulhão pequeno, Tachybaptus dominicus (Linnaeus, 1766), do estado de Minas Gerais, Brasil, trematódeos adultos identificados como Petasiger novemdecim Lutz, 1928 foram encontrados. A prevalência de infecção foi 55% (5/9) e a intensidade média de infecção 8 (1-32) parasitos. Adicionalmente, Biomphalaria straminea (Dunker, 1848) e Biomphalaria tenagophila (d'Orbigny, 1835) obtidas em coleções aquáticas do mesmo estado foram encontradas albergando duas espécies de cercárias do tipo equinóstoma pertencentes ao grupo Magnacauda. Estas cercárias desenvolveram-se em metacercárias em Poecilia reticulata Peters, 1859 experimentalmente infectados. Tentativas de obtenção de parasitos adultos em modelos experimentais (camundongos, frangos, patos e canários) demonstraram-se sem sucesso. O presente estudo é o primeiro relato de Petasiger em aves brasileiras e primeira descrição morfológica de larvas destes parasitos em moluscos do Brasil. Aspectos taxonômicos relacionados às espécies sul-americanas de Petasiger são discutidos. Sugere-se que, em vista das diferenças morfológicas observadas nos estágios larv...
