Case Presentation: A five-year-old female Gray Langur was rehabilitated at Wildlife Research & Training Centre, Gorewada, Nagpur, India. The Langur was found dead and a post mortem examination was conducted. Two cysts were detected, one on the liver and the other on the large intestine. The cysts were dissected and processed for histopathology investigation. Molecular investigation confirmed Cysticercus tenuicollis through PCR and Sequencing. The sequence was submitted to public domain database. Phylogenetic analysis found similarity with previously reported sequences from Asia and Europe. This was the first evidence of Cysticercus tenuicollis from India in a non-human primate.

Conclusion: The case report provides evidence of Cysticercus tenuicollis in Gray Langur. There are definite research gaps in the knowledge about the spread and wild reservoirs of the infection. The need to access the impact of the disease in endangered canids is essential.
