Molecular and morphological characterization of Contracaecum pelagicum (Nematoda) parasitizing Spheniscus magellanicus (Chordata) from Brazilian waters

“…Other morphological features such as number of papillae, length and shape of spicules in males, were similar to the ones previously described for C. pelagicum (LENT;FREITAS, 1948;SANTOS, 1984;FAGERHOLM et al, 1996;GARBIN et al, 2007), thus confirming the morphological diagnosis.…”

“…The species was first described from albatrosses from Australia and, since then the species was reported in South America from Thalassarche melanophris (=Diomedea melanophris (Temminck, 1828), the South American penguin, Spheniscus magellanicus (Forster, 1781), Spheniscus humboldti Meyen, 1834 and Sula leucogaster Boddaert, 1783 (LENT;FREITAS, 1948;SANTOS, 1984;MANN, 1992;SILVA et al, 2005;GARBIN et al, 2007;GONZÁLEZ-ACUÑA et al, 2008;EDERLI et al, 2009;DIAZ et al, 2010;PRADO et al, 2011;YÁÑEZ et al, 2012;REZENDE et al, 2013;CAMPOS et al, 2013).…”

Nematodes associated with Iguana iguana (Linnaeus, 1758) (Squamata, Iguanidae) in Semi-arid areas of Northeastern Brazil

“…Alaeuris caudatus has been recorded infecting this lizard in Brazil, Peru, Venezuela and Puerto Rico (Vicente et al, 1993;Dyer et al, 1999;Ávila and Silva, 2010), but there has been no report of the parasitological indices for abundance these species. There have been reports of A. vogelsangi infecting iguanas in the following countries: Brazil (Petter, 1970;Ávila and Silva, 2013), Puerto Rico (Dyer et al, 1999) and Venezuela (Lent and Freitas, 1948). In the Caatinga areas from Ceará, Brazil, Lopes et al (2007) noted prevalence 100% (3/3) and mean intensity of infection 4,866.6 ± 318,1, and Ávila and Silva (2011) registered prevalence 40% (2/5) and mean intensity of infection 9,604.5 ± 5,424.2 in Mato Grosso, Brazil.…”

Aplectana artigasi n.sp. (Nematoda: Cosmocercidae) from the Frog Eupsophus calcaratus (Anura: Leptodactylidae) in Southern Chile

“…No. 231555), from P. thaul (Benavides et al 1996) showed the characteristics of the original description of Lent and Freitas (1948), but the male specimen showed one unpaired papilla on the anterior lip of the anus, a characteristic that was not mentioned in the original paper.…”

“…Compared with descriptions of the above mentioned species by Miranda (1924), Travassos (1931), Lent andFreitas (1948), da Silva (1954), Pallarés and Maciel (1974) Baker (1980), Baker and Vaucher (1986) and Dyer (1990), the new species can be distinguished from A. membranosa, A. micropenis, A. vellardi, A. hylambatis, A. lopesi, A. elenae, A. paraelenae, A. pudenda, A. travassosi, and A. macintoshii because it does not have a gubernaculum.…”
