Abstract The aim of the present study was to evaluate the state of knowledge about the helminthology of wild mammals in Argentine Patagonia and its link with the conservation of parasite species and biodiversity. To this end, the information included in the previously reported checklist of the helminths found in terrestrial wild mammals of Argentine Patagonia was completed and updated. The methodology used for the search was the same as that previously used, with slight modifications. Eighty-two species of mammals currently inhabit the region, and an additional six species are considered to have become extinct before the 20th century. The reports used to complete and update the information correspond to research done since 2015 to date. Considering the number of records analysed in the previously reported checklist and those of the current update, a total of 1918 helminthological reports for current Patagonian mammals and 2141 on mammal species that inhabited Patagonia before the 20th century were accounted for. It is important to point out that 41% of the 82 species of wild mammals currently inhabiting Patagonia have not been studied helminthologically; 38% of these without helminthological records are either threatened or do not have categorization, and 79% of mammals without helminthological studies have some degree of endemism. Therefore, in order to evaluate conservation priorities, the information about the parasitic richness in Patagonian wild mammals should be substantially increased, especially in those endangered or endemic.

“…According to Quentin [ 13 ], the type Ascaridida, which corresponds to the most primitive arrangement of cloacal papillae, is present in rictulariids included in both genera Pterygodermatites and Rictularia , e.g., P. ( Paucipectines ) coloradensis , P. ( Pa. ) microti , P. ( Pa. ) ondatrae , P. ( Pa. ) zygodontomis , P. ( Neopaucipectines ) desportesi , R. citelli , R. dhanra , R. halli , R. lucifugus , R. macdonaldi , and R. proni , among others. After the review of Quentin [ 13 ], the Ascaridida type of arrangement of cloacal papillae has been described in other species, particularly those belonging to the subgenus P. ( Paucipectines ), e.g., P. ( Pa. ) andyraicola , P. ( Pa. ) argentinensis , P. ( Pa. ) baiomydis , P. ( Pa. ) chaetophracti , and P. ( Pa. ) hispanica [ 28 , 29 , 30 , 31 ]. With respect to the subgenus P. ( Pterygodermatites ), Le Roux [ 17 ] reported only three precloacal and five postcloacal pairs of cloacal papillae in P. ( P. ) aethechini .…”

New Data on Pterygodermatites (Pterygodermatites) plagiostoma Wedl, 1861 (Nematoda, Rictulariidae) Parasite of the Algerian Hedgehog Atelerix algirus Linnaeus, 1758 (Eulipotyphla: Erinaceidae) from the Canary Islands

A redescription of the rictulariid nematode Pterygodermatites (Pterygodermatites) plagiostoma Wedl, 1861, is made by means of light and scanning electron microscopy, including the first data on male specimens. The morphologic study was based on specimens recovered from two Algerian hedgehogs (Atelerix algirus) from Tenerife and Gran Canaria islands (Canary Archipelago, Spain). The main characteristics of P. (P.) plagiostoma males are the presence of 49–53 pairs of cuticular projections, the presence of one or two midventral precloacal fans (generally one), and the size of two unequal spicules, measuring 98–123 µm (right spicule) and 185–236 µm (left spicule). The cloacal papillae are arranged according to the Ascaridida type. They include two precloacal pairs, an unpaired precloacal papilla, one pair lateral to the cloaca, six postcloacal pairs, and a pair of phasmids near the tail tip. Females are mainly characterized by the presence of 71–77 pairs of cuticular projections, with 43–46 pairs of prevulvar combs, by the differentiation from combs to spines at the level of or slightly posterior to the vulva and by the position of the vulva, located posteriorly to the esophagus–intestine junction. Clear differences were found between P. (P.) plagiostoma and related species of the subgenus P. (Pterygodermatites).
