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.
