First record of Pterygodermatites (Pterygodermatites) (Nematoda: Rictulariidae) in South America, with the description of a new species from the Atlantic Forest, southeast Brazil

Abstract

Pterygodermatites are parasitic nematodes found in mammals worldwide, except Australia. There are 38 described species, which are found parasitizing bats, rodents, marsupials, carnivores and primates. We present taxonomic notes on nematodes collected from the digestive tract of bats from the Atlantic Forest in southeast Brazil. Two species previously recorded in marsupials in this region, Pterygodermatites (Paucipectines) elegans and Pterygodermatites (Paucipectines) jagerskioldi, were found parasitizing molossid and vespertilionid bats, respectively. A new species Pterygodermatites (Pterygodermatites) atlanticaensis found in phyllostomid bats is here described. Despite earlier work based on females, taxonomic work on this group of nematodes is usually based on male characters, such as position and number of caudal papillae, which is a problem because males are short-lived and not easily found. Here we also describe in detail female characters, such as position of the last pair of cuticular processes relative to the posterior end. This is the first record of P. (Pterygodermatites) in South America and the first record of P. (Paucipectines) jagerskioldi in bats.

Bat parasites (Acari, Anoplura, Cestoda, Diptera, Hemiptera, Nematoda, Siphonaptera, Trematoda) in France (1762–2018): a literature review and contribution to a checklist

“…The original description of the rare nematode P. (Neopaucipectines) bovieri is based on material from M. myotis in France. To my knowledge, it is the first published observation in the country (dated September 1885) [ 56 , 66 , 230 ]. The original descriptions of Riouxgolvania nyctali and R. rhinolophi are based on material from M. blythii and R. euryale in the Netherlands and the French departments of Ariège and Pyrénées-Orientales [ 20 , 21 ].…”

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

“…In fact, the differentiation of cuticular projections (from combs to spines) occurs at the level of the vulva in P. ( P. ) plagiostoma whereas it occurs at a posterior level in P. ( P. ) aethechini [ 17 ]. On the other hand, the vulva position is posterior to the esophagus–intestine junction in P. ( P. ) plagiostoma whereas it is anterior in P. ( P. ) atlanticaensis [ 18 ]. There is also a higher number of both prevulvar and total pairs of cuticular projections (combs and spines) (43–46/71–77) in P. ( P. ) plagiostoma in comparison to the number of these characters (40/66) in P. ( P. ) mexicana [ 16 ] although the number of cuticular projection pairs in P. ( P. ) plagiostoma (71–77) is surpassed by the 84 pairs described in P. ( P. ) shaldybini [ 13 ].…”

“…Pterygodermatites ( P. ) plagiostoma is present in several hedgehog species ( A. algirus , E. europaeus , H. auritus , and P. aethiopicus ), and has a wide geographical distribution, including North Africa (Algeria, Tunisia and Egypt), Saudi Arabia, and Spain [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. As for the remaining species of the subgenus, P. ( P. ) atlanticaensis and P. ( P. ) mexicana are parasites of bats in Brazil and Mexico [ 16 , 18 ], P. ( P. ) spinosa were detected in bats from Baviera (Germany) [ 12 ], P. ( P. ) shaldybini were found in bats and hedgehogs from Asia (Kazakstan, Turkmenistan, and Mongolia) [ 13 , 25 , 26 ], and P. ( P. ) aethechini were recorded in the hedgehog Atelerix frontalis from South Africa [ 16 ]. The present study enlarges the distribution of P. ( P. ) plagiostoma to the Tenerife and Gran Canaria islands (Canary Archipelago, Spain).…”

“…Pterygodermatites ( P. ) plagiostoma is the type species of both genus and nominal subgenus. The subgenus P. ( Pterygodermatites ) has only six species, namely P. ( P. ) plagiostoma , P. ( P. ) aethechini , P. ( P. ) atlanticaensis , P. ( P. ) mexicana , P. ( P. ) shaldibini , and P. ( P. ) spinosa [ 13 , 16 , 17 , 18 ]. In the original description of P. ( P. ) plagiostoma , Wedl [ 8 ] illustrates the caudal extremity of a male specimen showing two unequal spicules, but no other morphologic characteristic or measurements are presented.…”
