Species of the Genus Paroniella Fuhrmann, 1920 (Cestoda: Davaineidae) from Bulbuls (Passeriformes: Pycnonotidae): Redescription of P. perreti (Mahon, 1954) and Description of P. neolestes n. sp. from Africa
Purpose
The purpose of the present study is to contribute to the knowledge on the diversity of cestodes of the genus Paroniella Fuhrmann, 1920 parasitising passerine birds of the family Pycnonotidae (bulbuls) in the Afrotropical Region. The only known species of this groups, Paroniella perreti (Mahon, 1954) from Pycnonotus tricolor (Hartlaub) in the Democratic Republic of the Congo, is poorly described. Therefore, it needed a detailed redescription in order to make a reliable comparison and provide differentiation among this species and newly-collected davaineid specimens. Based on new materials collected from Neolestes torquatus Cabanis in Gabon, Paroniella neolestes n. sp. is described.
Methods
The type series of P. perreti from the collection of the Natural History Museum of Geneva is redescribed and figured using conventional light microscopy and interference-contrast microscopy. The specimens of the new species were stained by iron acetocarmine and mounted in Canada balsam.
Results
The present study provided more detailed and accurate data on P. perreti (compared to its original description) in relation mostly to the armament of suckers (not mentioned in the original description), the structure of the copulative apparatus, the number of rostellar hooks and the number of testes. The morphological comparison of the specimens from Neolestes torquatus from Gabon with the known 53 species of the genus Paroniella (presented in a table format) characterised them as belonging to a new species. The new combination Paroniella oitaensis (Kugi, 1990) n. comb. was proposed.
Conclusions
Based on the present state of knowledge, P. perreti and P. neolestes seem to be specific each to a single host species, i.e. Pycnonotus tricolor and Neolestes torquatus, respectively. Further studies of davaineid cestodes from pycnonotids from Africa as well as from South and Southeast Asia may result in discovering much greater diversity of this group than currently known.
期刊介绍：
Acta Parasitologica is an international journal covering the latest advances in the subject.
Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews.
The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
