“…Rego (1994) criticised tion and generical classification. Rego (1995) proposed a radical solution, which was to eliminate the taxa Monticelliidae, and to accept only one family, Proteocephalidae, for the South American species, with two subfamilies, Corallobothriinae and Proteocephalinae, for the species with or without a metascolex. Rego et al (1998) published a cladistic analyses of proteocephalid subfamilies; the Monticelliid sufamilies were provisionally maintained, depending of further phylogenetic analyses of the South American genera.…”

The morphology of the scolices and metascolices of 29 proteocephalid species, parasites of freshwater fishes from Brazil was compared by using scanning electron microscope, light and laser microscopy. The following species were evaluated: Proteocephalus vazzolerae, P. piramutab, Robertiella paranaensis, Travassiella avitellina, Monticellia loyolai, M. spinulifera, M. belavistensis, Houssayela sudobim, Zygobothrium megacephalum, Gibsoniela mandube, Cangatiella arandasi, Nomimoscolex sudobim, N. lopesi, N. admonticellia, N. piraeeba, N. pirarara, Harriscolex kaparari, Crepidobothrium eirasi, Spatulifer rugosa, Megathylacus brooksi, Choanoscolex abscisus, Amphoteromorphus peniculus, A. piraeeba, Paramonticellia itaipuensis, Peltidocotyle rugosa, Othinoscolex lenha, Rudolphiella rugata, R. piranabu, Jauella glandicephalus.Some features as overall shape of scolex, suckers, apical sucker, frontal glands and several kinds of metascolex were analyzed. The taxonomic importance of scolex and metascolex is discussed.Key words : Cestoda Proteocephalidea -parasites of freshwater fishes -South American fish parasites Proteocephalid Cestodes are parasites of freshwater fishes, specially Siluriforms (catfishes), Amphibia and Reptilia. They are the most importante parasites in Siluriforms, considering the number of parasite species described within those hosts.The morphology of the scolex is one of the most important characteristics used for classification of proteocephalids at generic and subamily level (Scholz et al. 1998). However, morphological features of scolex/metascolex have been neglected in the definition of the subfamilies and families, particularly in the classification of South American proteocephalids. Woodland (1933Woodland ( -1935 and the following authors preferred to utilise the characteristics of reproductive organs, and their relationships with the internal longitudinal musculature to separate the taxa. Rego (1995) disagreed with this scheme of classification, and proposed the elimination of the Monticelliidae and its subfamilies, based in the fact that the actual classification is not suitable for the forms of proteocephalids recently described, which present intermediate characteristics, and others with inconspicuous longitudinal musculature, resulting the impossibility of the definition of the taxa they belong to. Rego et al. (1998) carried a cladistic analysis based on comparative morphology, to examine the subfamily-level relationships within the order Proteocephalidea. The study did not evaluate relationships at the generic level, particularly those within the Monticelliidae (sensu Rego 1994). It is fundamental to conduct a phylogenetic analyses of the genera, to the resolution of taxonomic problems of South American proteocephalids. In that paper, on considering the character metascolex, only two states were considered (presence versus absence). However, several types of metascolex have been recognized by the authors. The goal of the present paper is to contributes to a definition and to distinguish t...

“…Therefore, our findings bring into question the restriction of this dense material to the basal cestodes proposed by Bruňanská and Poddubnaya (2010) on the base of available data at this time. In fact, the Proteocephalidea are considered the most closely related order to the Cyclophyllidea (Rego 1994(Rego , 1995. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 flagella resulting in the observation of two unequal flagella during spermiogenesis.…”

“…The Proteocephalidea Mola, 1928 have been recognized as an interesting group from an evolutionary point of view, because it was supposed to include the closest relatives of the ancestors of the Cyclophyllidea van Beneden in Braun, 1900 (Rego 1994(Rego , 1995. However, phylogenetically, they have also been regarded as a problematical group (Zehnder and Mariaux 1999, Škeříková et al 2001, Scholz and de Chambrier 2003, de Chambrier et al 2004).…”
