Two species of Digenea, Mesocoelium monas and Parallopharynx arctus, 1 species of Cestoda, Oochoristica gymnophthalmicola n. sp., 21 species of Nematoda, 19 species capable of completing their life cycle in lizards, Africana telfordi, Aplectana herediaensis, Cosmocercoides variabilis, Cruzia mexicana, Cyrtosomum longicaudatum, Macdonaldius grassi, Oswaldocruzia panamaensis n. sp., Oswaldofilaria brevicaudata, Ozolaimus cirratus, Parapharyngodon colonensis n. sp., Physaloptera retusa, Piratuba digiticauda, Skrjabinelazia galliardi, Skrjabinodon caudolumarius n. sp., Skrjabinodon crassicauda n. sp., Skrjabinodon scelopori, Spauligodon oxkutzcabiensis, Spinicauda spinicauda, and Strongyluris panamaensis, and 2 species utilizing lizards as paratenic hosts, Ophidascaris sp. (larvae) and Acuariidae gen. sp. (larvae in cysts), and 1 species of Acanthocephala (cystacanths), were found. Thirty-seven new host records and 13 new locality records are reported.

Gastrointestinal Helminths of 14 Species of Lizards from Panama with Descriptions of Five New Species

We examined 404 specimens representing 7 species of sceloporine lizards from Mexico (Sceloporus formosus, S. grammicus, S. megalepidurus, S. mucronatus, S. parvus, S. torquatus, and S. variabilis) for helminths. Two species of Cestoda (Oochoristica scelopori and Mesocestoides larvae) and 9 species of Nematoda (Atractis penneri, Physaloptera retusa, Spauligodon giganticus, S. oxkutzcabiensis, Strongyluris similis, Thubunaea intestinalis, Ascarops larvae, Physocephalus larvae, and Acuariidea larvae) were found. The mean number of helminth species for each species of lizard was 4.7 ± 1.5 SD (range = 3 to 7). Twenty-six new host records and 23 new locality records are reported.

Redescription of some Spauligodon spp. and Parapharyngodon spp., and of skrjabinodon mabuyae (Sandground, 1936) inglis, 1968 (Pharyngodonidae: Oxyuroidea) from insectivorous South African lizards.

Rhabdias leonae n. sp., a parasite of the lungs of Norops megapholidotus, is described and illustrated. The Mexican taxon differs from the other species in the genus by a combination of characters: possession of 4 lips, corpus slightly inflated, slightly postequatorial vulva, and presence of swollen cuticle of anterior and posterior ends. This is the 12th species described in the Neotropical realm and the first species of Rhabdias described from an endemic Mexican lizard.

A new rhabdiasid species from norops megapholidotus (sauria: polychrotidae) from mexico

Entomelas duellmani n. sp. (Rhabditida: Rhabdiasidae) from the lungs and Skrjabinodon cortagoensis n. sp. (Oxyurida: Pharyngodonidae) from the intestines of Mesaspis monticola (Sauria: Anguidae) are described and illustrated. E. duellmani is the sixth species assigned to the genus and is the third species described from the Western Hemisphere. It is easily separated from other neotropical species in the genus by pre-equatorial position of its vulva. Skrjabinodon cartagoensis is the 24th species assigned to the genus and differs from other neotropical species in the genus by female tail morphology.

Helminths in mesaspis monticola (squamata: anguidae) from costa rica, with the description of a new species of entomelas (nematoda: rhabdiasidae) and a new species of skrjabinodon (nematoda: pharyngodonidae)

Thubunaea ctenosauri sp n is described from the large intestine of the iguanid lizard Ctenosaura pectinata from Aguamilpa, Mexican State of Nayarit It is characterized mainly by the position of the vulva, number and distribution of caudal papillae, length of spicules (0066 mm), and size of eggs (0054-0060 X 0039-0042 mm) Other recorded species of parasitic nematodes are Skrjabinodon scelopori from Phyllodactylus lanei; Parapharyngodon alvarengai from P lanei, Anolis nebulosus, and Sceloporus nelsoni; and Atractis sce- lopori from C pectinata and Sceloporus sp The findings represent new host records, and P alvarengai is reported from Mexico for the first time
