Two new species of Pharyngodonidae (Nematoda, Oxyuroidea) in Gekko ulikovskii from Vietnam

Abstract

Pharyngodon duci sp. nov. and Spauligodon vietnamensis sp. nov. (Nematoda, Pharyngodonidae) from the large intestine of a gecko, Gekko ulikovskii (Sauria, Gekkonidae), from Vietnam are described and illustrated. Pharyngodon duci is the 35th species assigned to the genus and is separated from its congeners based upon the lack of a spicule, egg morphology, mouth morphology and cloacal lip morphology. Spauligodon vietnamensis is the 44th species assigned to the genus and is separated from its congeners by the lack of a spicule, egg morphology, and tail filament morphology.

A phylogenetic assessment of the colonisation patterns in Spauligodon atlanticus Astasio-Arbiza et al., 1987 (Nematoda: Oxyurida: Pharyngodonidae), a parasite of lizards of the genus Gallotia Boulenger: no simple answers

“…Recent descriptions of new Spauligodon spp. still rely on morphology only (Binh et al, 2007;Bursey et al, 2007;Monks et al, 2008). S. atlanticus was also described based exclusively on morphological characters.…”

“…Spauligodon Skrjabin, Schikhobalova & Lagodovskaja, 1960 (Oxyurida) is a cosmopolitan genus of intestinal nematodes that comprises at least 46 described species (Binh et al, 2007;Bursey et al, 2007;Monks et al, 2008), with 20 of them occurring in the Palaearctic region (Bursey et al, 2005). S. atlanticus Astasio-Arbiza, Zapatero-Ramos, Ojeda-Rosas & Solera-Puertas, 1987 was described as an obligate parasite specific to lacertid lizards of the genus Gallotia Boulenger endemic to the Canary Islands .…”

Pharyngodon mamillatus (Nematoda: Pharyngodonidae) in the ocellated skink Chalcides ocellatus (Squamata: Scincidae) from Egypt: Light and scanning electron microscopic studies

“…According to the egg morphology, it differs from P. lepidodactylus Bursey and Goldberg (1996) and P. oceanicus in having bottle‐shaped eggs with cuticular knobs at poles in the former and unadorned poles in the latter; P. asterostoma Adamson (1984), P. australis Johnston and Mawson (1942), P. brevibursata Caballero Rodriguez (1968), P. cesarpintoi , P. cnemidophori , P. hierrensis Solera‐Puertas et al (1988), P. hispanicus , P. kirbii , P. tiliquae Adamson (1984), P. warneri , P. duci Binh et al (2007), and P. yucatanensis in having eggs with truncated ends. At both the morphological and morphometric levels, it could be identified as P. mamillatus .…”

A new species of Pharyngodon (Nematoda, Pharyngodonidae) and other helminths in Cyrtodactylus louisiadensis (Sauria, Gekkonidae) from Papua New Guinea

“…elongata Markov et Bogdanov, 1961;P. sphaerodactyli Barus et Coy Otero, 1974;and, P. polypedatis Yamaguti, 1941(Binh et al 2007. The purpose of this paper is to describe the 36th species assigned to Pharyngodon.…”
