Protospirura siamensis n. sp (Nematoda: Spiruridae) from rodents in Thailand

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.
