“…Some authors, for example Moravec et al (1997), considered that the morphological features of Thubunaea and Physalopteroides have rarely been analysed using techniques such as SEM, and that these observations could provide detailed information to assess the validity of these two genera. However, to the best of our knowledge, SEM studies are still scarce in both genera, being available for only three species of Thubunaea (Moravec et al 1997, Pazoki and Rahimian 2014, Ramallo et al 2016) and two species for Physalopteroides (Elwasila 1990, Goswami et al 2016). The specimens described in the present study show a symmetrical cephalic structure, as in Thubunaea .…”

A total of 61 specimens of the Red-headed Spiny Lizard Sceloporus pyrocephalus Cope (Phrynosomatidae) collected during the breeding season (June/July 2003, 2004 and 2005) from Western Mexico were examined for helminths. The morphological characterization of the helminths found was made through light microscopy and scanning electron microscopy. Nine taxa of helminths were identified, two cestodes: Mesocestoides sp. and Oochoristica sp., and seven nematodes: Parapharyngodon ayotzinapaensis Garduño-Montes de Oca, Mata-López & León-Règagnon, 2016, Parapharyngodon tikuinii Garduño-Montes de Oca, Mata-López & León-Règagnon, 2016, Parapharyngodon sp., Physalopterinae gen. sp., Skrjabinoptera scelopori Caballero-Rodríguez, 1971, Strongyluris similis Caballero, 1938 and a new species of Thubunaea Seurat, 1914. Larvae of Mesocestoides sp. and Physalopterinae gen. sp. were found in the body cavity and digestive tract, respectively. Excluding the species of Parapharyngodon Chatterji, 1933, S. pyrocephalus is recorded for the first time as a host of the remaining seven taxa of helminths. Additionally, Thubunaea leonregagnonae sp. n. is described and illustrated as a new nematode species, parasite of S. pyrocephalus from Mexico. This new species can be differentiated from the majority of its congeners by the absence of spicules, the particular pattern of caudal papillae in males and the small ratio of oesophagus length:male total body length (0.1–0.16).

“…In L. parvus, Parapharyngodon riojensis was found to be associated with the stomach. However, for other species like L. buergeri, L. ruibali, and species of the genus Phymaturus, nematodes were located in the long intestine (Ramallo et al, , 2016(Ramallo et al, , 2017Goldberg et al, 2004;Castillo et al, 2017aCastillo et al, , 2018.…”

The objective of this study was to describe temporal variations in the diet and parasitological aspects in Liolaemus parvus. In order to examine the diet, we determined the volume, numerousness, and frequency of occurrence for each prey item and calculated the relative importance index. We removed nematodes from the stomach and estimated parasitic indicators. Liolaemus parvus presents an active searching mode. It is a predominantly insectivorous species with low intake of plant material and a specialist in feeding on prey items of the family Formicidae, although it also feeds on other arthropods like coleopterans, hemipterans, and spiders. We found temporal variations in its diet. The first record of Parapharyngodon riojensis nematodes is reported herein. Males showed higher nematode prevalence than females. We have expanded the number of host species and the distribution range of Parapharyngodon riojensis. The information provided about trophic ecology and parasitism is the first contribution to this lizard species' biology.

“…The information available on metazoan parasites of the herpetofauna from the Monte desert in Argentina mostly refers to helminth species found in reptiles (Ramallo and Díaz, 1998;Ramallo et al, 2002a;2002b;2016a;2017;Goldberg et al, 2004). Regarding helminths found in amphibians, González et al (2013a) described the nematode Falcaustra sanjuanensis González, Sanabria and Quiroga, 2013 from the large intestine of Odontophrynus cf.…”

Here we describe a new cosmocercid nematode, Aplectana nebulosa sp. nov., from the small and large intestines of Pleurodema nebulosum (Anura: Leptodactylidae), from the Monte desert of San Juan, Argentina. The new species belongs to the Aplectana group that possesses a gubernaculum and unpaired adcloacal papilla anteriorly to cloaca. It resembles A. membranosa, A. paraelenae and A. travassosi by the presence of four adcloacal papillae, but differs from those species by the following characters: number and arrangement of precloacal papillae; number and arrangement of postcloacal papillae; shape and size of spicules and gubernaculum, and by the presence of lateral alae in caudal region of males. The description of the new species is based on light microscopy and scanning electron microscopy (SEM) and we also provide a key to Neotropical species of Aplectana.
