  "abstract": "The genus Oochoristica Lühe, 1898 (Cyclophyllidea: Linstowiidae) primarily parasitizes reptiles. A new species of Oochoristica was collected from the small intestine of Eremias roborowskii (Bedriaga, 1906), from the Turpan Basin of the Xinjiang Uygur Autonomous Region, China. Following hematoxylin staining, through microscopic examination and detailed morphological description, a comparative morphometric analysis was conducted against closely related congeners, with particular emphasis on key taxonomic indicators, including the reproductive system and cephalic structures. Phylogenetic relationships were inferred using a multilocus analysis based on the 18S rRNA, ITS1-5.8S-ITS2 and COI gene regions. Genetic distances were calculated to support species delimitation. The parasite exhibits the following diagnostic features: proglottids significantly wider than long; a scolex lacking a rostellum and hooks; 20–25 spherical testes clustered in the posterior region of the proglottid; genital pores irregularly alternating along the lateral margins; a bilobed, highly branched ovary; and an elliptical vitellarium situated anterior to the ovary. Phylogenetic trees demonstrated that the new species formed a distinct, well-supported clade with lower intraspecific genetic variation than interspecific divergence, thereby supporting its status as an independent species. This new species is the 19th Oochoristica taxon recorded in the Palaearctic realm and the first novel cestode found in Eremias roborowskii. In the present study, an integrative taxonomic approach was employed, which combined comparative morphology with molecular phylogenetics and zoogeographic analyses, thereby elucidating the phylogenetic significance of this species within the genus Oochoristica.",
