Seventeen specimens of Bodianus diplotaenia (Gill) (Labridae), 22 Calamus brachysomus (Lockington) (Sparidae) and 18 Pronotogrammus multifasciatus Gill (Serranidae), were examined. Three new species of Dactylogyridae n. gen.; two new species of Euryhaliotrema Kritsky & Boeger, 2002, two new species of Haliotrema Johnston & Tiegs, 1922 and a new species of Parancylodiscoides Caballero y Caballero & Bravo-Hollis, 1961 were described: Dactylogyridae n. gen., n. sp1., Dactylogyridae n. gen., n. sp2. and Dactylogyridae n. gen., n. sp3. from P. multifasciatus, Euryhaliotrema luisae Cruces, Chero & Luque, 2018; Euryhaliotrema magnopharyngis Cruces, Chero & Luque, 2018 and Haliotrematoides mediohamides Kritsky e Mendoza-Franco, 2009 from C. brachysomus, Haliotrema diplotaenia Cruces, Chero & Luque, 2018 and Haliotrema saezae Cruces, Chero & Luque, 2018 from B. diplotaenia and Parancylodiscoides n. sp. of P. multifasciatus. Dactylogyridae n. gen. is mainly characterised by having broadly fork-shaped dorsal anchors, which have an accessory anchor sclerite articulated to tip of the superficial roots. In addition, Dactylogyridae n. gen. is also characterized by: (1) a tubular tapered-shaped male copulatory organ (MCO), filamentous distally, with a counterclockwise coil at distal end or not, lacking accessory piece; (2) a dorsal bar with an anteromedial umbelliform membrane supported by two processes; (3) hooks with upright blunt thumb and uniform shank; (4) a vaginal aperture dextrolateral; and (5) eye-spot or chromatic granules absent. Euryhaliotrema luisae from C. brachysomus is distinguished from other species of the genus by the morphology of the MCO, which comprises a coil of nine counterclockwise rings, and by the morphology of the anchors and bars. Euryhaliotrema magnopharyngis from C. brachysomus can be distinguished from all other congeners by having a well-developed pharynx occupying much of the anterior region and by the ventral bar, which is V-shaped, with well-elongated, thin arms. In addition, E. luisae and E. magnopharyngis can be differentiated from all other members of Euryhaliotrema by the presence of a glandular oval plate lying on peduncle. Haliotrema diplotaenia from B. diplotaenia is characterized by the structure of the CMO, comprising a tapered-shaped cirrus tube with twisted acute tip and a filament-shaped accessory piece with medial and distal expansions. Haliotrema saezae from B. diplotaenia differs from all other members of Haliotrema by having a tubular copulatory organ with curved distal tip and a filament-shaped accessory piece without lateral expansions. Parancylodiscoides n. sp. from P. multifasciatus could be differentiated from all other congeners by the morphology of the MCO, which is a sinuous sclerotized tube with filament-like distal end. Additionally, new morphological data on H. mediohamides are presented in the present study. Uma pesquisa parasitol?gica foi realizada para coletar dactilogir?deos (Monogenea) que infestam as br?nquias de peixes marinhos da zona costeira do Puerto Pizarro, Regi?o de Tumbes, Peru, em maio de 2017 e fevereiro de 2019. Dezessete esp?cimenes de Bodianus diplotaenia (Gill) (Labridae), 22 Calamus brachysomus (Lockington) (Sparidae) e 18 Pronotogrammus multifasciatus Gill (Serranidae), foram examinados. Tr?s novas esp?cies de Dactylogyridae n. gen.; duas novas esp?cies de Euryhaliotrema Kritsky e Boeger, 2002, duas novas esp?cies de Haliotrema Johnston & Tiegs, 1922; uma nova esp?cie de Parancylodiscoides Caballero y Caballero e Bravo-Hollis, 1961 e uma esp?cie de Haliotrematoides Kritsky, Yang & Sun, 2009 foram descritas: Dactylogyridae n. gen., n. sp1., Dactylogyridae n. gen., n. sp2. e Dactylogyridae n. gen., n. sp3. de P. multifasciatus, Euryhaliotrema luisae Cruces, Chero e Luque, 2018; Euryhaliotrema magnopharyngis Cruces, Chero e Luque, 2018 e Haliotrematoides mediohamides Kritsky e Mendoza-Franco, 2009 de C. brachysomus, Haliotrema diplotaenia Cruces, Chero e Luque, 2018 e Haliotrema saezae Cruces, Chero e Luque, 2018 de B. diplotaenia e Parancylodiscoides n. sp. de P. multifasciatus. Dactylogyridae n. gen. ? caracterizado principalmente por possuir ?ncoras dorsais em forma de garfo, tendo um esclerito acess?rio articulado ? ponta da raiz superficial. Al?m disso, Dactylogyridae n. gen. tamb?m ? caracterizado por ter: (1) um ?rg?o copulador masculino (COM) tubular com forma c?nica, distalmente filamentoso, com um anel no sentido anti-hor?rio na extremidade distal ou n?o, sem pe?a acess?ria; (2) uma barra dorsal com uma membrana anteromedial suportada por dois processos; (3) ganchos com ?ded?o? ereto e l?mina uniforme; (4) uma abertura vaginal dextrolateral; e (5) gr?nulos crom?ticos ou ocelos ausentes. Euryhaliotrema luisae de C. brachysomus ? diferenciada de outras esp?cies do g?nero pela morfologia do OCM, que compreende uma estrutura em forma de bobina de nove an?is no sentido anti-hor?rio e pela morfologia das ?ncoras e barras. Euryhaliotrema magnopharyngis de C. brachysomus pode ser distinguido de todos os outros cong?neres por ter uma faringe bem desenvolvida ocupando grande parte da regi?o anterior e pela barra ventral, em forma de V, com bra?os finos e alongados. Al?m disso, E. luisae e E. magnopharyngis podem ser diferenciados de todos os outros membros de Euryhaliotrema pela presen?a de uma placa oval glandular apoiada no ped?nculo. Haliotrema diplotaenia de B. diplotaenia ? caracterizada pela estrutura do OCM, compreendendo um tubo c?nico com ponta aguda torcida e uma pe?a acess?ria em forma de filamento com expans?es mediais e distais. Haliotrema saezae de B. diplotaenia difere de todos os outros membros de Haliotrema por possuir um OCM tubular com ponta distal curva e uma pe?a acess?ria em forma de filamento sem expans?es laterais. Parancylodiscoides n. sp. de P. multifasciatus pode ser diferenciado dos cong?neres pela morfologia do OCM, que ? um tubo esclerotizado sinuoso com a extremidade distal semelhante a um filamento. Adicionalmente, novos dados morfol?gicos de H. mediohamides s?o presentadas no presente estudo. |
