Abstract

Rhabdias pearsoni Kuzmin et Tkach, sp. n. is described based on specimens found in the lung of the keelback Tropidonophis mairii (Gray, 1841) from southern Queensland, Australia. The new species is most similar morphologically to Rhabdias horigutii Yamaguti, 1943 and Rhabdias vibakari Kuzmin, 1999 with all three species lacking buccal capsule. The new species differs from R. horigutii by the smaller circumoral lips and papillae, and shorter tail. R. pearsoni sp. n. differs from R. vibakari by position of the nerve ring (in R. vibakari, it is closer to the anterior end than in the new species) and shorter tail. Australian R. pearsoni sp. n. is geographically isolated from R. horigutii and R. vibakari, both occurring in Eastern Asia.
