Skrjabinodon heliocostai sp.n. (Nematoda, Pharyngodonidae) parasitizing Mabuya frenata (Cope) (Lacertilia, Scincidae) in Brazil and the reallocation of Skrjabinodon capacyupanquii (Freitas, Vicente & Ibanez) in the genus Thelandros Wedl

Abstract

ABSTRACT. The present report is related to an oxyurid nematode recovered from a reptilian host, Mabllya jrenata (Cope, 1862) and the proposal of Slajabinodoll helicostai sp.n., based mainly on findings referring to the lateral alae, position of excretory pore and vulvar apet1ures, cuticular spines of the tail and aspect of the eggs. The examination of types of Skljabillodoll capacyupanquii (Freitas, Vicente & Ibanez, 1968) from a Peruvian lizard, indicated the reallocation of this species in the genus The/alldros Wed!., 1862, as T. capacYllpcmqllii comb.n., based on the diameter of the caudal appendage of males and position of the vulvar aperture. The new species described herein represents the first rep0\1 of a species of the genus Slajabillodoll Inglis, 1968 in South America. KEY WORDS. Nematodes, Skljabillodoll, new species, The/andros, new combination, lizard, South America Nematodes occurring in Brazilian reptiles were fully reported from 1861 to 1988 (VICENTE et af. 1993b) when several nematode species have been referred parasitizing lizards in Brazil. Nevertheless, only a couple of them are related to Scincidae hosts, namely Mabuya maboya mabouya (Lace pede, 1788) and M maculata (Gray, (839). The present findings are related to the proposition ofa new taxon and a new combination regarding nematode species from reptilian hosts in Brazil and Peru, respectively. MATERIALS AND METHODSTwo-hundred and thirty-two lizards Mabuyafrenata (Cope) were captured between 1993-1995. Worms were recovered in a 0.85% NaCI solution, fixed in hot 700GL ethanol and were processed for study as described elsewhere (VICENTE et af. 1993a).

Checklist of helminths from lizards and amphisbaenians (Reptilia, Squamata) of South America

“…(117), this oxyurid was incorrect described in "Libro de Resumenes del IV Congreso Nacional de Biologia", a meeting abstract. Due to an inaccordance with articles 8.1 and 9.9 of the International Code for Zoological Nomenclature, it was therefore considered a species inquirenda (107,118 (165). Moreover, the species was cited in Guillén-Hernández et al (166).…”

Pulmonary infection in two sympatric lizards, Mabuya arajara (Scincidae) and Anolis brasiliensis (Polychrotidae) from a cloud forest in Chapada do Araripe, Ceará, Northeastern Brazil

“…Despite the numerous studies on lizard parasites in Brazil (Rocha, 1995;Ribas et al, 1998;Vrcibradic et al, 1999;Vicente et al, 2000;Vrcibradic et al, 2001;Vicente et al, 2002;Vrcibradic et al, 2002a, b;Anjos et al, 2005;Bursey et al, 2010), most focus on species of lizards restricted to biomes and ecosystems from the Southeast region. In relation to lung parasites, only two host species were studied in skinks, Mabuya agilis (Raddi, 1823), which was recorded as a host of an unidentified species of the pentastomid Raillietiella sp.…”

New Species of Skrjabinodon (Nematoda: Pharyngodonidae) in Uracentron Flaviceps (Squamata: Iguanidae) From Ecuador and Peru

“…is most similar to those species lacking a spicule (see Table I), namely, S. apapillosus (Koo, 1938), S. dossae (Caballero, 1968), S. heliocostai Vicente, Vrcibradic, Muniz-Pereira andPinto, 2000, S. leristae Mawson, 1971, S. mabuiensis (Malan, 1939), S. megalocerca (Skrjabin, 1916), S. ovocaudatus Caballero, 1968, S. pigmentatus Markov and Bogdanov, 1961, and S. smythi Angel and Mawson, 1968. Of these, only males of S. dixoni, S. leristae, and S. smythi have cuticular spines on the tail filament.…”

“…Four species of Skrjabinodon Inglis, 1968 are currently known from neotropical lizards (Table I): S. cricosaurae Barus and Coy Otero, 1974 from the Cuban night lizard (Cricosaura typical), collected in Cuba; S. heliocostai Vicente, Vrcibradic, Muniz-Pereira and Pinto, 2000 from Cope's mabuya (Mabuya frenata), collected in Brazil; S. spinulosus Vicente, Vrcibradic, Rocha and Pinto, 2002 from the Paraguay mabuya (Mabuya dorsivittata), also collected in Brazil; and S. scelopori (Caballero, 1938) from the crevice swift (Sceloporus torquatus), collected in Mexico (Caballero, 1938;Barus and Coy Otero, 1974;Vicente et al, 2000Vicente et al, , 2002. The purpose of this paper is to describe a new species of Skrjabinodon.…”
