J. Helminthol. Soc. Wash. 66(2), 1999 pp. 175-179 Skrjabinodon piankai sp. n. (Nematoda: Pharyngodonidae) and Other Helminths of Geckos (Sauria: Gekkonidae: Nephrurus spp.) from Australia CHARLES R. BURSEYU AND STEPHEN R. GOLDBERG2 1 Department of Biology, Pennsylvania State University, Shenango Campus, Sharon, Pennsylvania 16146, U.S.A. (e-mail: cxbl3@psu.edu), and 2 Department of Biology, Whittier College, Whittier, California 90608, U.S.A. (e-mail: sgoldberg@whittier.edu) ABSTRACT: Skrjabinodon piankai sp. n. from the large intestine of the Australian gecko Nephrurus laevissimus is described and illustrated. It is also reported from Nephrurus levis and Nephrurus vertebralis. Skrjabinodon piankai differs from 6 other Australian realm species in the number of tail filament spines and egg shape. Other helminths found include Oochoristica piankai, Maxvachonia brygooi, Pharyngodon tiliquae, Physalopteroides filicauda, Wanaristrongylus ctenoti, third-stage larvae of Abbreviata sp., third-stage larvae of Physaloptera sp., and Raillietiella scincoides. New host records are established for O. piankai and R. scincoides in N. laevissimus; M. brygooi and P. filicauda in N. levis; and P. tiliquae in N. vertebralis. KEY WORDS: Skrjabinodon piankai sp. n., Pharyngodonidae, helminths, Nephrurus laevissimus, Nephrurus levis, Nephrurus vertebralis, Gekkonidae, Sauria, Australia. Four species of Skrjabinodon Inglis, 1968 have been reported previously from reptiles of Australia. Parathelandros oedurae Johnston and Mawson, 1947, was originally described from specimens taken from the robust velvet gecko, Oedura robusta Boulenger, 1885, collected in southeast Queensland. Inglis (1968) revised Parathelandros Diesing, 1861, retaining the genus for parasites of Australian amphibians and erecting Skrjabinodon as a new genus for parasites of reptiles; 7 species, including P. oedurae, were placed in the new genus. Skrjabinodon smythi Angel and Mawson, 1968 was described from the marbled gecko, Christinus (=Phyllodactylus) rnarmoratus (Gray, 1845) collected in South Australia. Skrjabinodon parasmythi Mawson, 1971, from the thick-tailed gecko, Underwoodisaurus milii (Bory de Saint-Vincent, 1825), and Skrjabinodon leristae Mawson, 1971, from a skink, Lerista sp., were described from specimens collected on Flinders Island, South Australia. In addition, 2 species, Skrjabinodon trimorphi Ainsworth, 1990, from the common skink, Leiolopisma nigriplantara Patterson and Daugherty, 1990, and Skrjabinodon poicilandri Ainsworth, 1990 from the common gecko, Hoplodactylus maculatus Boulenger, 1885, have been described from specimens collected in New Zealand (Ainsworth, 1990). 3 Corresponding author. Nephrurus Giinther, 1876, is an endemic Australian gecko genus containing arid-adapted species characterized by large heads and short, fat tails that terminate in a small knob (Cogger, 1992). The spinifex knobtail gecko, Nephrurus laevissimus Mertens, 1958, occurs in southeastern Western Australia, northwestern South Australia, and southern parts of the Northern Territory; the smooth knobtail gecko, Nephrurus levis De Vis, 1886, occurs from the central coast of Western Australia to the arid parts of all states except Victoria; Storr's knobtail gecko, Nephrurus vertebralis Storr, 1963, occurs from the lower central interior of Western Australia to South Australia (Cogger, 1992). The ranges of these 3 nocturnal species overlap in Western Australia (Cogger, 1992). However, they are reported to favor different habitats (Pianka, 1972): TV. laevissimus is associated with sandridges; N. levis occurs on sandplains vegetated with dense clumps of perennial grasses of Triodia Brown, 1810; and N. vertebralis is associated with shrubs of Acacia Miller, 1754. There are 4 previous reports of nematodes from N. laevissimus (Jones, 1985, 1987, 1995a, b), 1 report from N. levis (Jones, 1995b), but, to our knowledge, no reports from N. vertebralis. We describe here a new species of Skrjabinodon that was found in the large intestines of TV. laevissimus, N. levis, and N. vertebralis from Western Australia and the Northern Territory and list other helminth parasites found in these hosts. 175 Copyright © 2011, The Helminthological Society of Washington
