RESUMEN
A new species of filarioid nematode of the genus Breinlia Yorke & Maplestone, 1926 (Nematoda: Filarioidea) is described from rodents in Lao PDR and according to its morphology, is placed in the subgenus Breinlia. Breinlia (Breinlia) jittapalapongi n. sp. occurs in the Asian house rat (Rattus tanezumi Temminck) and the Sikkim rat (Rattus andamanensis Blyth) and is reported from two localities (Luang Prabang and Champasak). The new species can be distinguished from all other congeners, which are mostly distributed in Australasia (twenty-two species), South East Asia (four species) and India (two species), by the following characters of the males: shape and size of gubernaculum, length of spicules, pattern of cloacal papillae and presence of sclerotised ring in the buccal capsule. This is the fifth species of Breinlia described from South East Asia.

During a study of the helminth fauna of 1,643 rodents trapped along the Mekong River (Thailand, Lao People's Democratic Republic and Cambodia) in 2008-2011, the spirurid nematode Physaloptera ngoci Le-Van-Hoa, 1961 was recovered with an overall prevalence of 2.8%. Based on the original description, it was identified in nine of 23 different Murinae host species and is here reported for the first time from these three countries. A scanning electron microscopy study provides additional morphological data.

A large number (828) of rodents belonging to nine genera (Bandicota, Berylmys, Chiropodomys, Hapalomys, Leopoldamys, Maxomys, Mus, Niviventer and Rattus) were trapped in four Thai provinces between 2008 and 2010. A new species of Protospirura (Nematoda: Spiruridae) was identified and described. Protospirura siamensis n. sp. was found in 10 rodent species from the four Thai provinces surveyed. The new species can be distinguished from known species of the genus by the arrangement of the papillae on the male and the morphology and length of the spicules. This is the first species of Protospirura to be described from South-East Asia.
