Primula atrodentata W. W. Sm. (Primulaceae) is recorded for the first time from the Trans-Himalayan region of Ladakh in India. The present study provides a taxonomic description, photographs of diagnostic features and distribution map of the species. Comparison of delimiting characters between P. atrodentata and closely related P. denticulata are provided to validate the new distribution record for the region. The species' differs from P. denticulata in lacking basal bud scales, black-colored sepals and mauve or pale blue-violet corolla with a prominent white or creamy eye. In addition, IUCN threat status of P. atrodentata was empirically assessed for the first time which revealed the species as Near Threatened (NT). In an era of rapid land-use and climate changes, the results from present study have wide relevance in devising successful conservation strategies for this endemic species in high-altitude habitats of the Himalaya.
