Abstract
Aplectana samarensis sp. nov. (Ascaridida, Cosmocercidae) from the intestines of Limnonectes magnus (Anura, Dicroglossidae) is described and illustrated. Aplectana samarensis sp. nov. represents the 53rd species assigned to the genus and the 6th species reported from the Oriental region. It is easily separated from the 5 species previously reported from the region by the presence of a gubernaculum and the distribution pattern of male caudal papillae: A. macintoshii has an irregular pattern, no precloacal papillae in rows; both A. akhrami and A. dubrajpuri lack a gubernaculum; A. duttaphryni has 3 pairs of precloacal papillae forming 2 rows; A. ranae has 7 pairs of precloacal papillae forming 2 rows; A. samarensis sp. nov. has 4 pairs of precloacal papillae in 2 rows. In addition to the new species, individuals of Falcaustra dubia and Pseudoacanthocephalus bufonis as well as cestode plerocercoids were also found.
