Cyrtosomum penneri n. sp. (Oxyuroidea; Atractidae)

Origin of the Helminth Community of an Exotic Invasive Lizard, the Brown Anole,Anolis sagrei(Squamata: Polychrotidae), in Southwestern Taiwan

“…One hundred and thirty one (96% of infected hosts) anoles were infected by C. penneri; 13 anoles (9%) by M. monas, one anole (<1%) by a Parapharyngodon sp., and one anole by an Table 2, two species of Cyrtosomum have been reported in A. sagrei from Florida: C. penneri by Goldberg et al (1994) and C. scelopori Gedoelst, 1919, by Price and Underwood (1984). Cyrtosomum penneri can be distinguished from C. scelopori by the spic ule appearance: the spicules of C. scelopori are equal in length (Gedoelst 1919), and those of C. penneri are unequal in length (Gambino 1957). We have assigned our specimens to C. penneri because the males possess spicules of unequal length.…”

“…Population terminology is ac cording to Bush et al (1997). Statistical anal ysis followed the methods outlined by Brower et al (1998 Gambino, 1957 (large and small intestines), an unidenti fied species of Parapharyngodon (large intes tine), and a larva of an acuariid nematode (small intestine). The number, prevalence (number of infected host species as percent age), mean intensity (mean number of hel minths per infected host), and abundance (t otal number of parasites in a host sample di vided by total number of hosts in the sample) by helminth species are given in Table 1.…”
