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. © 2012 Springer Science+Business Media B.V.Mahidol UniversityImmunology and MicrobiologyArticleSCOPUS10.1007/s11230-012-9343-1
