Two New Species of Cosmocercids (Ascaridida) in the Toad Chaunus Arenarum (Anura: Bufonidae) From Argentina

Abstract

Aplectana tarija n. sp. and Cosmocercoides lilloi n. sp., intestinal parasites of the toad Chaunus arenarum, are described. Of the 41 nominal species of Aplectana, A. tarija n. sp. represents the 22nd Neotropical species and the second species reported from Argentina. Of the 14 nominal species of Cosmocercoides, C. lilloi n. sp. represents the 15th species and the first species reported from South America.

Primer registro de nematodos parásitos de Physalaemus santafecinus (Anura: Leiuperidae) de Corrientes, Argentina

“…Also, 5 species of genus Aplectana: A. tarija Ramallo, Bursey and Goldberg, 2007 in Rhinella arenarum; A. adaechevarriae Ramallo, Bursey and Goldberg, 2008 in R. granulosa and R. schneideri from Salta Province (Ramallo et al, 2007;2008); A. meridionalis Lent andFreitas, 1948 in Pleurodema borellii (Peracca, 1895) from Jujuy Province (Baker, 1980); A. delirae (Fabio, 1971) in R. granulosa from Corrientes Province, and, A. hylambatis in bufonids from Salta, Córdoba, Buenos Aires and Corrientes Provinces and, in leptodactylids from Corrientes Province (Gutierrez, 1945;Sueldo and Ramírez, 1976;Ramírez et al, 1979;González and Hamann, 2006b;Hamann et al, 2006aHamann et al, , 2006b) have been found. In this study, P. santafecinus represents new host record for C. podicipinus, C. parva and A. hylambatis.…”

“…Many studies in nematode parasites of amphibians have been recently conducted in the Neotropical Realm, including a description of new species or genus (González and Hamann, 2004, 2007aBursey and Goldberg, 2007;Martínez-Salazar and León-Règagnon, 2007;Ramallo et al, 2007Ramallo et al, , 2008Martínez-Salazar, 2008) as well as, checklists that summarize the diversity of these parasites in these vertebrate hosts González and Hamann, 2006b, 2007b, 2009Bursey, 2008a, 2008b;. Despite the fact that many species of parasites are cited in a wide variety of hosts, there are few studies that deal with the morphological and metrical aspects of these nematodes.…”

Study of Helminth Parasites of Amphibians by Scanning Electron Microscopy

“…76). Lavilla et al (2000) reported a total of 271 amphibian species for Argentina (167 anurans and 4 gymnophions); of these, only 32 (11.8%) have been cited as hosts for helminth parasites (González and Hamann, 2004, 2009, 2010a, 2010b, 2011Hamann and Pérez, 1999;Hamann et al, 2006aHamann et al, , 2006bHamann et al, , 2009aHamann et al, , 2009bHamann et al, , 2010Lajmanovich and Martinez de Ferrato, 1995;Lunaschi and Drago, 2007;Ramallo et al, 2007aRamallo et al, , 2007bRamallo et al, , 2008. Of all the anuran families, the most studied for helminth parasites are Hylidae, Bufonidae, Leiuperidae and Leptodactylidae.…”

A newCosmocercoidesspecies (Ascaridida: Cosmocercidae),C. wuyiensisn. sp., from the Asiatic frogAmolops wuyiensis(Amphibia: Anura)

“…in the small intestine. To our knowledge, 25 species of Cosmocercoides have been reported so far, distributed across China (Baylis, 1927; Hsü, 1933; K'ung & Wu, 1945; Wang, 1980; Wang et al , 1981; Chen et al , 2018), India (Karve, 1944; Khera, 1958; Arya, 1979, 1991; Rao, 1979; Rizvi, 2009; Rizvi & Bursey, 2014), Japan (Wilkie, 1930), Malaysia (Bursey et al , 2015), Ceylon (Ogden, 1966), Vietnam (Tran et al , 2015), Argentina (Ramallo et al , 2007), Brazil (Ávila et al , 2010), USA (Holl, 1928; Harwood, 1930), Mexico (Martínez-Salazar et al , 2013), Ukraine (Ivanitzky, 1940) and Italy (Ricci, 1987). These nematodes usually parasitize amphibians (17 species known so far) and reptiles (eight species), but are occasionally detected in land snails and slugs as well (Vanderburgh & Anderson, 1986).…”
