Two New Species of Encotyllabe (Monogenea: Capsalidae) from Brazil: Morphological and Molecular Evidence

et al. 2023

Currently, 24 species of Encotyllabe Diesing, 1850 (Monogenea: Capsalidae), are recorded as parasites on teleost fishes, but the validity of many species has been questioned due to deficient or incomplete descriptions. Almost all species in the genus have been described from one host species or closely related host species, suggesting host specificity, but some species, specifically Encotyllabe spari Yamaguti, 1934, have been reported from at least 19 species belonging to nine families in two orders (Perciformes and Scorpaeniformes) from Japan, Arabian Gulf and Brazil. Concerning Brazilian records of Encotyllabe spari and Encotyllabe cf. spari, seven species belonging to four families and two orders have been reported as hosts for this species. The aim of this study was to describe two new species of Encotyllabe from Brazil, previously considered as E. spari. Morphological and morphometric (multivariate analysis of proportional measurements standardized by total length) and molecular analysis (LSU rRNA and cox1 gene) were performed in order to identify the collected monogeneans. The description of two new species, namely Encotyllabe bifurcatum n. sp. and Encotyllabe parvum n. sp., parasitizing Pagrus pagrus and Orthopristis ruber, respectively, is the result of the three approaches. The main morphological differences from the most related species include a combination of body size, shape of the male copulatory organ, size and position of the testes. Our results suggest host specificity for members of Encotyllabe and specimens previously recorded as E. spari, other than those from the original description, must be revisited.

“…Finally, the Laboratory of Evolutionary Helminthology from USP includes a productive group focusing on the taxonomy of cestodes parasitic in Chondrichthyes (Marques et al ., 2012; Marques & Reyda, 2015). It is also important to highlight the activity of researchers from UFRRJ in several studies on the ecology of parasites from fish (Amarante et al ., 2015; Soares & Luque, 2015), which is a subject equally explored by the research group from the Laboratory of Ichthyoparasitology, UEM, State of Paraná (southern Brazil) (Bellay et al ., 2015a, b). Also in Paraná, the group formed by researchers from the Department of Zoology of the UFPR, have produced one of the most impressive collections of literature on the morphological and molecular taxonomy of monogeneans (Boeger et al ., 2014b, 2015).…”

Helminth parasites of South American fishes: current status and characterization as a model for studies of biodiversity

et al. 2016

The South American subcontinent supports one of the world's most diverse and commercially very important ichthyofauna. In this context, the study of South American fish parasites is of increased relevance in understanding their key roles in ecosystems, regulating the abundance or density of host populations, stabilizing food webs and structuring host communities. It is hard to estimate the number of fish parasites in South America. The number of fish species studied for parasites is still low (less than 10%), although the total number of host-parasite associations (HPAs) found in the present study was 3971. Monogeneans, with 835 species (1123 HPAs, 28.5%), and trematodes, with 662 species (1127 HPAs, 30.9%), are the more diverse groups. Data gathered from the literature are useful to roughly estimate species richness of helminths from South American fish, even though there are some associated problems: the reliability of information depends on accurate species identification; the lack of knowledge about life cycles; the increasing number of discoveries of cryptic species and the geographically biased number of studies. Therefore, the closest true estimations of species diversity and distribution will rely on further studies combining both molecular and morphological approaches with ecological data such as host specificity, geographical distribution and life-cycle data. Research on biodiversity of fish parasites in South America is influenced by problems such as funding, taxonomic impediments and dispersion of research groups. Increasing collaboration, interchange and research networks in the context of globalization will enable a promising future for fish parasitology in South America.

“…With regard to the Brazilian records, E. spari (but also E. cf. spari) has been recorded from at least four species of Haemulidae, Conodon nobilis, Anisotremus surinamensis, Haemulun sciurus and Orthropristis ruber; one species of Sparidae, Pagrus pagrus (Sparidae); two species of Sciaenidae (Menticirrhus americanus, Micropogonias furnieri); and one species of Dactylopteridae (Dactylopterus volitans) [15,16,20,22,25,26] (Table 3). Our data challenge the low host speci city of Encotyllabe from Brazil; worms from the Sparid Pagrus and those from the Haemulid Orthopristis ruber belong to different species, as demonstrated by molecular tools (Fig.…”

BackgroundCurrently, 24 species of Encotyllabe Diesing, 1850 (Monogenea: Capsalidae) are listed in WoRMS, but the validity of many species has been questioned due to deficient or incomplete descriptions. On the other hand, almost all species in the genus have been described from one host species or closely related host species, suggesting host specificity, but other species, specifically Encotyllabe spari Yamaguti, 1934, have been reported at least from 19 species belonging to nine families in two orders (Perciformes and Scorpaeniformes) from Japan, the Arabian Gulf and Brazil. Concerning Brazilian records of Encotyllabe spari (but also as Encotyllabe cf. spari); seven host species belonging to four families and two orders have been reported as hosts for this species. The aim of this study was to describe two new species of Encotyllabe from Brazil, previously considered as E. spari.MethodsDuring 2016, we examined specimens of Orthophristis ruber (Cuvier) (Haemulidae) and Pagrus pagrus (Linnaeus) (Sparidae) caught off the coast of Cabo Frio, Rio de Janeiro, Brazil by local fishermen. Specimens of Encotyllabe were collected from the pharyngeal plates of the hosts. Morphological and morphometric (multivariate analysis of proportional measurements standardized by total length) and molecular analysis (LSU rRNA and cox1 gene) were performed in order to identify the collected monogenea. ResultsThe presence of two new species of Encotyllabe, Encotyllabe yamagutii n. sp. and Encotyllabe haemuli n. sp., parasitizing the pharyngeal plates of Pagrus pagrus and Orthopristis ruber, respectively, is strongly suggested by the three approaches used in this study. The main morphological differences from the most related species include a combination of body size, shape of the penis, and size and position of the testes.ConclusionsSpecimens of Encotyllabe, hitherto recorded as E. spari or E. cf. spari, belong to two new species. Our results suggest that the host specificity for members of Encotyllabe and specimens registered as E. spari, other than those from the original description, must be revisited.
