“…Centrorhynchus guira differs from C. nahuelhuapensis by having a larger body (26.1–50.4 mm in C. guira vs 10.8–41 mm in the new species), a shorter proboscis (790–1000 μm in C. guira ), a larger proboscis receptacle (1400–1770 μm in C. guira vs 625–1575 μm in C. nahuelhuapensis ), more hooks per row (18–19), a different proboscis hook formula (8 – 9 + 4 – 6 + 6), and shorter true hooks (males 24–48 μm, females 31–48 μm in C. guira vs males 37–62 μm, females 37–77 μm in C. nahuelhuapensis ), and shorter spiniform hooks (14–26 μm in C. guira vs 17–40 μm in the new species). It also differs by having a bigger egg (53–64 μm long by 24–29 μm wide in C. guira vs 50–59 μm long by 14–17 μm wide in C. nahuelhuapensis ) (Lunaschi and Drago, 2010; Smales, 2013).…”

“…The species recorded from South America parasitize a wide range of birds in different families, e.g. Ardeidae, Cuculidae, Accipitridae, Falconidae, Furnariidae, Trudidae, Tyrannydae, Thamnophillidae and Strigidae (Lunaschi and Drago, 2010; Smales, 2013; Drago et al ., 2015; Grandón-Ojeda et al ., 2018). The only species of Centrorhynchus reported from Argentina is C. guira , described from the intestine of the guira cuckoo ( G. guira ) from northern Argentina (Lunaschi and Drago, 2010) and from Crotophaga ani (Linnaeus) recorded in Paraguay (Smales, 2013).…”

“…Centrorhynchus spinosus Kaiser, 1893 was recently recovered from Bubo maguellanicus (Lesson) in Chile (Grandón-Ojeda et al ., 2018). In Argentina, specimens of C. guira were found parasitizing Guira guira (Gmelin) (the guira cuckoo) and Theritiscus caudatus (Boddaert) (the buff-necked ibis) (Lunaschi and Drago, 2010; Lunaschi et al , 2015). Also recently one immature male specimen of Centrorhynchus sp.…”

Centrorynchus nahuelhuapensis n. sp. is described from the intestine of Strix rufipes, the rufous-legged owl, in Patagonia, Argentina. This species is characterized by the presence of 31–33 hook rows with 16–17 hooks per row, distributed as follows: 5 true hooks, 4 transitional hooks with 4 alate processes, more evident in the first three, 7–8 spiniform hooks, and three cement glands. It differs from most members of the genus by having a filiform body, the arrangement and size of the hooks, the number of cement glands, and egg size. Part of the SSU and LSU genes were sequenced and compared to those in GenBank. Sequences are most similar to other species of Centrorhynchus, supporting their placement within this genus. We present the first molecular study for a species of Centrorhynchus from South America. Additionally, it is the second species of the genus described in Argentina, and the first species of a terrestrial acanthocephalan from a bird in Patagonia.

“…However, new species can not be assigned to any of them based on other characteristics. In particular, C. albidus has at least 7, and C. guira has 8-9 first hooks in each row with large blades and powerful roots (Meyer, 1932;Lunaschi, Drago, 2010) vs 4-6, more often 5 in C. polissiensis sp. n. In C. javanicus and C. brama the anterior part of the proboscis bears first 10 hooks of each longitudinal row (Rengaraju, Das, 1975, 1980 vs 12-13 hooks in C. polissiensis sp.…”

The article presents the results of the investigation of material on the genus Centrorhynchus Lühe, 1911 stored in the collection of the Department of Parasitology, Schmalhauzen Institute of Zoology, National Academy of Sciences of Ukraine. Five species: Centrorhynchus aluconis, C. globocaudatus, C. spinosus, C. conspectus and C. polissiensis sp. n. were studied and described. Centrorhynchus polissiensis sp. n., differs from all known species by the complex morphological characters, in particular, by the formula of proboscis hooks in combination with the number of large hooks with roots, by the number of hooks in anterior part of the proboscis, and by comparatively smaller eggs. C. polissiensis sp. n. is most similar to C. aluconis, C. conspectus and C. globocaudatus. The main differences between the species are in the proboscis armament, 13–17 hooks in a longitudinal row in C. aluconis, 16–18 hooks in C. conspectus vs 19–20 hooks in C. polissiensis sp. n., and in the egg sizes, 56–65 × 28–30 for C. aluconis, 68–72 × 33–35 for C. conspectus vs 45–55 × 25 for C. polissiensis sp. n. C. polissiensis sp. n. differs from C. globocaudatus in shape and morphology of the proboscis hooks. We do not confirm the record of C. amphibius from birds of the territory of Ukraine. The data on synonymy, hosts and distribution in Ukraine and in the world are given for seven species of the genus recorded in Ukraine. Illustrated descriptions about the material of collection are presented for five species. We provide an identification key for nine species of the genus Centrorhynchus of the birds of the fauna of Ukraine and adjacent territories.

En el presente trabajo se abordan aspectos taxonómicos y ecológicos de los helmintos parásitos asociados a 12 especies de tres familias de murciélagos de 11 localidades de la provincia de Corrientes y una de Misiones: Eumops patagonicus, Eumops perotis, Molossops temminckii, Molossus molossus, Molossus rufus (Molossidae), Artibeus lituratus, Desmodus rotundus, Platyrrhinus lineatus, Sturnira lilium (Phyllostomidae), Eptesicus furinalis, Myotis albescens y Myotis cf nigricans (Vespertilionidae). Se describió la presencia y caracterizaron morfológicamente 12 taxones de helmintos: dos especies de cestodes Vampirolepis guarany y V. cf macroti (Hymenolepididae), siete especies de digeneos Anenterotrema eduardocaballeroi, A. liliputianun (Anenterotrematidae), Gymnoacetabulum talavarensis, Ochoterenatrema labda, Paralecithodendrium aranhai (Lecithodendriidae), Limatulum oklahomense (Phaneropsolidae), Urotrema scabridum (Urotrematidae) y tres taxones de nematodes Anoplostrongylus sp. (Trichostrongylidae), Pterygodermatites sp. (Rictulariidae) y Capillaria sp. (Trichuridae). Para cada taxón se elaboró una ficha taxonómica y un mapa de distribución a fin de visualizar los registros previos y el aporte de este estudio. Se efectuó la modificación parcial del inventario actual que compendia los helmintos parásitos de murciélagos de la región neotropical y se elaboró un inventario sobre los helmintos parásitos de murciélagos de Argentina. Se evaluaron 212 murciélagos, cuya prevalencia general de infección parasitaria fue 61,3%. Se observó que U. scabridum es la especie con mayor distribución hospedatoria, estando presente en seis especies de murciélagos de las familias Molossidae (E. patagonicus, M. temminckii, M. molossus y M. rufus) y Vespertilionidae (M. albescens y M. cf nigricans), al contrario A. liliputianum y Pterygodermatites sp. estuvieron presentes en una sola especie hospedadora (M. rufus y E. patagonicus respectivamente). A excepción de A. liliputianum, se amplía el rango de especies hospedadoras de todas las especies de helmintos hallados. Respecto a los cestodes se registran nueva asociación entre V. guarany y A. lituratus y entre Vampirolepis cf macroti y E. furinalis. En los digeneos se registran cuatro nuevas asociaciones entre O. labda y E. patagonicus, M. temminckii, M. rufus, M. albescens; dos entre U. scabridum y E. patagonicus, M. albescens; dos entre G. talavarensis y E. patagonicus, M. albescens; dos entre P. aranhai y E. patagonicus, Myotis cf nigricans; dos entre L. oklahomense y M. rufus,M. albescens y una entre A. eduardocaballeroi, M. temminckii. En cuanto a los nematodes se registran cuatro nuevas asociaciones entre Anoplostrongylus sp. y E. patagonicus, E. perotis, M. rufus, E. furinalis; tres nuevas asociaciones entre Capillaria sp. y M. temminckii, M. rufus, S. lilium y una entre Pterygodermatites sp. y E. patagonicus. Al orientar estos resultados con una perspectiva regional, se pone de relieve la contribución del presente estudio al conocimiento parasitológico de los murciélagos de Argentina elevando el número de especies de helmintos conocidas para el país de 20 a 25 y enriqueciendo el inventario faunístico de helmintos asociados a nueve especies de murciélagos con 23 nuevas asociaciones. La continuidad y profundización del estudio taxonómico y la aproximación en las estimaciones ecológicas, como fueron desarrolladas en esta investigación, permiten avanzar en el conocimiento y generar las bases para el estudio sobre la relación parásito/hospedador/ambiente y su impacto en la fauna parasitaria de animales silvestres, domésticos e incluso el hombre.
