Aplectana krausi sp. nov. (Ascaridida, Cosmocercidae) from the intestines of Platymantis boulengeri (Anura, Ceratobatrachidae) is described and illustrated. Aplectana krausi represents the 42nd species assigned to the genus, the 4th species reported from the Australo-Papuan region. It is easily separated from the three species previously reported from the region by the distribution pattern of male caudal papillae: A. macintoshii and A. novaezelandiae have irregular patterns; A. zweifeli and A. krausi have defined patterns. Aplectana zweifeli has 8–10 precloacal, no adcloacal, and 9 postcloacal pairs of papillae, there is a single median papillae just anterior to the cloaca; A. krausi has 5 precloacal, 1 adcloacal, and 5 postcloacal pairs of papillae, a median papillae is absent.
Oxyascaris mcdiarmidi sp. nov. (Nematoda, Cosmocercidae) from the small intestine of Duellmanohyla uranochroa from Costa Rica is described. Oxyascaris mcdiarmidi sp. nov. represents the 4th species assigned to the genus and is distinguished from congeners by the distribution pattern of the caudal papillae of the male, spicule length and vulvar position.
Cosmocerca oroensis sp. nov. (Ascaridida, Cosmocercidae) from the large intestine of Barygenys atra (Anura, Microhylidae) is described and illustrated. Cosmocerca oroensis represents the 26th species assigned to the genus and the 7th from the Australo-Papuan biogeographical region. Cosmocerca oroensis sp. nov. differs from the previously described Australo-Papuan species in number of plectanes: C. oroensis with 2 pairs; C. australis, 3–4 pairs; C. archeyi, C. tyleri and C. zugi, 4 pairs; C. limnodynastes and C. novaeguineae, 5 pairs. In addition to the new nematode species, Meteterakis crombiei (Nematoda, Heterakidae) was also found.
Thelandros vietnamensis sp. nov. (Oxyuroidea, Pharyngodonidae) from the intestines of an agamid lizard, Leiolepis reevesi, collected in Vietnam is described and illustrated. Thelandros vietnamensis represents the 3rd Oriental species to be described and is distinguished from all other species by length of spicule (485–536 μm) of the male; all other species have spicules less than 200 μm.
Two new nematode species, Bakeria schadi sp. nov. and Falcaustra malaysiaia sp. nov. from the gastrointestinal tract of McGuire’s rock gecko, Cnemaspis mcguirei (Sauria: Gekkonidae) collected in Peninsular Malaysia are described. The two species now assigned to Bakeria are separated on the bases of male bursa type and location of the excretory pore: type II in B. schadi sp. nov. and type I in B. bakeri; location of excretory pore, anterior to nerve ring in B. schadi sp. nov. and posterior to nerve ring in B. bakeri. Falcaustra malaysiaia sp. nov. is most similar to F. chabaudi, F. concinnae, F. condorcanquii, F. barbi, F. dubia, and F. tchadi in that these 7 species possess 1 pseudosucker, 1 median papilla plus 10 pairs caudal papillae, and spicules with lengths between 1 and 2 mm. F. barbi and F. tchadi lack adcloacal papillae; the remaining 5 species possess 1 pair of adcloacal papillae. Falcaustra chabaudi is known from Nearctic salamanders; F. concinnae from Nearctic turtles; F. condorcanquii from Neotropical frogs, F. dubia from Oriental frogs, and F. malaysiaia sp. nov. from Oriental geckos. Two additional species of Nematoda were found, Cosmocerca ornata and Meteterakis singaporensis. Cnemaspis mcguirei represents a new host record for Cosmocerca ornata and Meteterakis singaporensis.
Two new nematode species, Orientatractis hamabatrachos sp. nov. and Rondonia batrachogena sp. nov. (Nematoda: Atractidae), from the gastrointestinal tract of Austrochaperina basipalmata (Anura: Microhylidae) collected in Papua New Guinea are described. Orientatractis hamabatrachos sp. nov. is characterized by the presence of the cephalic end armed with 4 wellsclerotized structures, consisting of 2 “horns” extending outward and downward and immediately below a single well-sclerotized spine. It differs from 5 congeners in spicule lengths and caudal papillae arrangements. Rondonia batrachogena sp. nov. is characterized by the presence of a female cloaca. It differs from 2 congeners primarily in body size. Orientatractis hamabatrachos sp. nov. and Rondonia batrachogena sp. nov. represent the first species assigned to either genus found to infect anurans or to occur in the Australo-Papuan region.
Mathevotaenia panamaensis sp. nov. (Cestoda, Anoplocephalidae, Linstowiinae) from a green spiny lizard, Sceloporus malachiticus, collected in Panama is described. This is the first species of Mathevotaenia reported from a lizard host. The new species is most similar to Mathevotaenia bivittata in that mature eggs are concentrated along the lateral margins of the proglottids. Major differences between the two species include oval cirrus sac in M. bivittata, a spherical cirrus sac in M. panamaensis; ovary compact consisting of 10–15 short lobules in M. bivittata, ovary bilobed with each lobe consisting of 3–4 lobules in M. panamaensis.
Falcaustra desilvai sp. nov. (Ascaridida, Kathlaniidae) from the large intestine of Cnemaspis aff. tropidogaster (Squamata, Gekkonidae) is described and illustrated. Falcaustra desilvai represents the 4th nematode species from Sri Lanka to be assigned to the genus and is distinguished from other Sri Lankan species by the distribution pattern of caudal papillae (12 precloacal, 2 adcloacal, 10 postcloacal, and 1 median), length of spicules (956–1046 μm) and absence of a pseudosucker.
Maxvachonia ingens sp. nov. from the intestines of Litoria darlingtoni (Hylidae) from Papua New Guinea is described and illustrated. Maxvachonia ingens sp. nov. represents the 7th species assigned to the genus and the 5th from the Australo-Papuan Region. The new species differs from other species assigned to Maxvachonia by the position of the vulva in the female (the only species with a post-oesophageal position) and the spicule/gubernaculum ratio of the male (the only species with ratio greater than 1). Females of the new species are most similar to M. dimorpha and M. ewersi in that the posterior ends of these three species are rounded. These species are easily separated: M. ewersi possesses lateral alae, the other 2 do not; the posterior end of M. dimorpha terminates in a mucro, M. ingens sp. nov. lacks terminal ornamentation.
Cosmocerca tyleri sp. nov. (Ascaridida, Cosmocercidae) from the large intestine of Genyophryne thomsoni (Anura, Microhylidae) is described and illustrated. Cosmocerca tyleri sp. nov. represents the 23rd species assigned to the genus and the 6th from the Australian realm. Of the 5 Australian species previously described, C. tyleri sp. nov. differs from C. limnodynastes and C. novaeguineae in number of plectanes, 4 pairs in C. tyleri, 5 pairs in C. limnodynastes and C. novaeguineae. Cosmocerca australis has 3–4 pairs of plectanes, C. archeyi and C. zugi each have 4 pairs of plectanes; however, in each species the plectanes lie in the fourth quarter of the body and just anterior to the cloaca. In C. tyleri sp. nov. the plectanes lie in the third quarter of the body and there is significant space between the cloaca and the posterior pair of plectanes.
Falcaustra papuensis sp. nov. (Ascaridida, Kathlaniidae) from the large intestine of Sphenomorphus simus (Squamata, Sciencidae) is described and illustrated. Falcaustra papuensis represents the 4th Australo-Papuan species assigned to this genus and is distinguished from other Australo-Papuan species by the distribution pattern of caudal papillae (6 precloacal, 6 adcloacal, 8 postcloacal, and 1 median), length of spicules (561–714 μm) and presence of a pseudosucker. Sphenomorphus simus was found to harbor 2 additional species of nematodes, Meteterakis crombiei and Oswaldocruzia bakeri. Sphenomorphus simus represents a new host record for each of these nematode species.
Pharyngodon novaeguineae sp. nov. from the large intestines of Cyrtodactylus louisiadensis (Sauria, Gekkonidae), from Papua New Guinea is described and illustrated. Pharyngodon novaeguineae represents the 36th species assigned to the genus and is separated from its congeners based upon absence of a spicule, egg morphology, and excretory pore position.
