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.

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 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.

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.
