Acanthocephalans Of The Genus Centrorhynchus (Palaeacanthocephala, Centrorhynchydae) From Birds Of Ukraine With The Description Of A New Species

Abstract

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.

New data on helminth fauna of birds of prey (Falconiformes, Accipitriformes, Strigiformes) in the Slovak Republic

“…On the other hand, C. buteonis has been documented not only in Falconiformes and Accipitriformes, but also in owls, especially in the Strix genus (Furmaga, 1957;Yamaguti, 1963;Michálek, 1984;Kritscher, 1985;Sitko 2011;Dimitrova & Dimitrova, 2012;Shirazi et al, 2014). The widest host range, as confi rmed by the above mentioned authors, was observed in C. globocaudatus, primarily infecting diurnal raptors (Sanmartín et al, 2004;Lisitsyna & Greben, 2015). Within our research, a total of 23 helminth species consisting of ten Trematoda species, six Cestoda species, fi ve taxa of the Secernentea class, and one species of Paleacanthocephala were observed for the fi rst time in birds of prey from Slovakia.…”

“…The majority of literature data on acanthocephalans of birds of prey suggests a rather low host specifi city of individual species of the Centrorhynchus genus. For instance, C. aluconis is considered as an owl parasite in Europe (Kutzer et al, 1982;Kritscher 1985;Ewald & Crompton, 1993;McInnes et al, 1994;Sitko 1994;Dimitrova et al, 1995;Ferrer et al 2004;Dimitrova & Dimitrova 2012;Santoro et al, 2012b;Lisitsyna & Greben, 2015), but it has sometimes been observed also in diurnal raptors (Yamaguti 1963, Illescas Gomez et al 1993Borgsteede et al 2003, Sitko 2011. On the other hand, C. buteonis has been documented not only in Falconiformes and Accipitriformes, but also in owls, especially in the Strix genus (Furmaga, 1957;Yamaguti, 1963;Michálek, 1984;Kritscher, 1985;Sitko 2011;Dimitrova & Dimitrova, 2012;Shirazi et al, 2014).…”

Description and molecular analysis of an Italian population of Centrorhynchus globo caudatus (Zeder, 1800) Lühe, 1911 (Acanthocephala: Centrorhynchidae) from Falco tinnunculus (Falconidae) and Buteo buteo (Accipitridae)

“…Descriptive reports variably document its morphology using only line drawings. Among these, we consider the line drawings in Petrochenko (1950) and Lisitsyna & Greben (2015) to be the most complete and adequately representative. Minor exceptions are noted.…”

“…Setting the record straight • Lisitsyna & Greben (2015) stated that the proboscis has a 'maximum width at the anterior part' of males and females and their Fig. 3a shows a posterior proboscis constriction.…”

Gastrointestinal and external parasites of the Variable hawk Geranoaetus polyosoma (Accipitriformes: Accipitridae) in Chile

“…Centrorhynchus includes about 90 described species which parasitize a wide variety of avian hosts, being the most speciose acanthocephalan genus parasitic in birds (GOLVAN, 1994). A great number of Centrorhynchus species parasitising diurnal and nocturnal raptors were reported from Italy, Ukraine, Slovakia, USA and Ivory Coast (RICHARDSON & NICKOL, 1995;DIMITROVA & GIBSON, 2005;SANTORO et al, 2010SANTORO et al, , 2012KOMOROVÁ et al, 2015;LISITSYNA & GREBEN, 2015). In South America, there are reports of larval stages (cystacanths) of Centrorhynchus spp.…”
