Abstract
Rhabdias garhwalensis sp. nov. from the lungs of Duttaphrynus himalayanus (Günther, 1864) collected in Kimoi Tehsil, district Tehri Garhwal (Uttarakhand), India is described and illustrated. Rhabdias garhwalensis sp. nov. represents the 15th species described from the Oriental zoogeographical zone and the 9th species from India. The new species is differentiated from the closely related Oriental species in having 6 lips, cup–shaped buccal cavity with muscular striations in the posterior region and smaller esophagus to body length ratio. In addition to the new species, a second species, Cosmocercoides bufonis Karve, 1944, was found in the large intestine of D. himalayanus .
