Heterophyid trematodes (Digenea) from penguins: A new species of Ascocotyle Looss, 1899, first description of metacercaria of Ascocotyle (A.) patagon…
2019
Two species of heterophyid trematodes were found in the Magellanic penguin, Spheniscus magellanicus (Forster), from Patagonia, Argentina. Ascocotyle (Ascocotyle) patagoniensis Hernández-Orts et al. (2012) is re-described based on new, properly fixed specimens (original material from South American sea lion, Otaria flavescens Shaw, was from frozen hosts). Metacercariae of this species are reported and described for the first time from the heart of the silversides, Odontesthes argentinensis (Valenciennes) and O. smitti (Lahille), from Patagonia. Ascocotyle (Phagicola) cameliae n. sp. is described from the intestine of S. magellanicus. The new species is placed into the subgenus Phagicola Faus…
Revision ofHalisiphoniaAllman, 1888 (Cnidaria, Hydrozoa, Hebellidae), with comments on its taxonomic position
2006
The deep‐water genus Halisiphonia is reviewed, based on redescriptions of all available type specimens of its species. The genus includes four valid species, H. arctica, H. galatheae, H. megalotheca, and H. nana, and one species inquirenda, H. spongicola, for which the type could not be located.
<p><strong>Revision of the Antarctic species of <em>Halecium</em> Oken, 1815 (Cnidaria, Hydrozoa, Haleciidae)</strong>&…
2014
A revision of the known Antarctic species of the genus Halecium has been carried out, based on the study of both type and non-type material. For each species a list of synonyms, a diagnosis, a broad description (with the exception of the recently described H. frigidum and H. exaggeratum), a discussion of its relationship with other members of the genus, and an account of its autecological data are given. Thirteen Antarctic species of the genus, including H. pseudodelicatulum sp. nov. and H. pseudoincertus sp. nov., are considered valid. Halecium tubatum is considered as species inquirenda. Halecium ovatum and H. macrocaulus are considered to be junior synonyms of H. interpolatum and H. ince…
Revision of the genus Filellum Hincks, 1868 (Lafoeidae, Leptothecata, Hydrozoa)
2011
A taxonomic review of the cosmopolitan genus Filellum was performed considering morphology, morphometry and cnidome. Species for which we had access to materials were redescribed and morphologically characterized based on optical and scanning electron microscopy (SEM). The materials examined belong to museum collections, including type specimens. All records found in the literature were checked. Our analyses confirmed the validity of 10 out of the 18 nominal species referred to the genus, and established four others (F. adnatum, F. bouvieri, F. contortum and F. plicatum) as species inquirenda. A new species, Filellum bouvetensis sp. nov., is described. The species Reticularia annulata Watso…
