A NewPhysaloptera(Nematoda: Physalopteridae) Parasite ofTupinambis merianae(Squamata: Teiidae) from Southeastern Brazil

Abstract

Physaloptera tupinambae n. sp. (Nematoda: Physalopteridae) collected from the stomach of 1 Tupinambis merianae (Squamata: Teiidae) male lizard is described. Physaloptera tupinambae, which belongs to the didelphys group, is the only species in the genus that exhibits a bipartite internal tooth and in which the excretory pore is anterior to the deirids. The new species can be differentiated from the other congeners mainly based on the number and pattern of caudal papillae and the length and shape of spicules. Physaloptera murisbrasiliensis and Physaloptera clausa orientalis are the only physalopterids with the same number of caudal papillae as for P. tupinambae, but they differ from the new species mainly in length and shape of spicules. Based on morphological analysis, the speciation process among Physaloptera probably occurred via host capture, and P. tupinambae occupies an intermediate phylogenetic position in the genus. Most likely, the new parasite was acquired by the lizard through ingestion of an intermediate host. Finally, Physaloptera calotisi, Physaloptera funambuli, Physaloptera guptae, Physaloptera indica, Physaloptera johnsoni, Physaloptera kherai, and Physaloptera thaparus are moved to Abbreviata.

New records of Helminths in Reptiles from five states of Brazil

“…Paracapillaria, Dracunculus and Physaloptera are considered generalists, being frequently reported infecting amphibians and reptiles (Torres and Puga, 1996;Timi et al, 2007;Moravec and Santos, 2009;Pereira et al, 2012).…”

“…Erythrolamprus viridis and Ceará state is a new host and new locality record for P. liophis. Physaloptera tupinambae (Pereira et al, 2012) can be distinguished from the other Neotropical species of Physaloptera by length of spicules and by possessing a bipartite internal tooth (Pereira et al, 2012).…”

“…Moreover, parasitism is a key feature in population dynamics and community structure (Ernst and Ernst, 1980). Inventories of helminths from reptiles are relatively frequent and are very useful for filling the gaps in the ecological and taxonomic knowledge, for they enhance and constitute the development and the comprehension of the parasitism in the vertebrates (Muzzall, 2005;Pereira et al, 2012;Albuquerque et al, 2013;Cabrera-Guzmán and Garrido-Olvera, 2014).…”

Helminths of the Lizard Salvator merianae (Squamata, Teiidae) in the Caatinga, Northeastern Brazil

“…The nematodes were cleared using lactophenol, mounted on temporary slides, analyzed with a microscope and identified through the literature (Pereira et al, 2012(Pereira et al, , 2014Vicente et al, 1993). Subsequently, they were deposited in the Parasitological Collection of the Regional University of Cariri (URCA-P: 444-466).…”
