Background  The Tibetan antelope  Pantholops hodgsonii  (Abel) (Artiodactyla: Bovidae) is an endangered species of mammal endemic to the Qinghai-Tibetan Plateau. Parasites and parasitic diseases are considered to be important threats in the conservation of the Tibetan antelope. However, our present knowledge of the composition of the parasites of the Tibetan antelope remains limited.    Methods  Large numbers of nematode parasites were collected from a dead Tibetan antelope. The morphology of these nematode specimens was observed using light and scanning electron microscopy. The nuclear and mitochondrial DNA sequences, i.e. small subunit ribosomal DNA ( 18S ), large subunit ribosomal DNA ( 28S ), internal transcribed spacer (ITS) and cytochrome  c  oxidase subunit 1 ( cox 1), were amplified and sequenced for molecular identification. Moreover, phylogenetic analyses were performed using maximum likelihood (ML) inference based on  28S  and  18S  +  28S  +  cox 1 sequence data, respectively, in order to clarify the systematic status of these nematodes.    Results  Integrated morphological and genetic evidence reveals these nematode specimens to be a new species of pinworm  Skrjabinema longicaudatum  (Oxyurida: Oxyuridae). There was no intraspecific nucleotide variation between different individuals of  S. longicaudatum  n. sp. in the partial  18S ,  28S , ITS and  cox 1 sequences. However, a high level of nucleotide divergence was revealed between the new species and its congeners in  28S  (8.36%) and ITS (20.3–23.7%) regions, respectively. Molecular phylogenetic results suggest that the genus  Skrjabinema  should belong to the subfamily Oxyurinae (Oxyuroidea: Oxyuridae), instead of the subfamily Syphaciidae or Skrjabinemiinae in the traditional classification, as it formed a sister relationship to the genus  Oxyuris .    Conclusions  A new species of pinworm  Skrjabinema longicaudatum  n. sp. (Oxyurida: Oxyuridae) is described.  Skrjabinema longicaudatum  n. sp. represents the first species of Oxyurida (pinworm) and the fourth nematode species reported from the Tibetan antelope. Our results contribute to the knowledge of the species diversity of parasites from the Tibetan antelope, and clarify the systematic position of the genus  Skrjabinema .
