Abstract
We describe a new species of the genus Mesalina from Rajasthan, India. The new species is genetically distinct and belongs to the M. watsonana species complex, and differs from all other congeners in a combination of morphological characters, such as 10 upper labials; eight lower labials; two large transparent shields of lower eyelid accompanied with three smaller shields; scales on tibia keeled; ventral plates in eight straight longitudinal series, ventral plates in 30 transverse rows; 34 dorsal granular scales across middle of back; nine collars; five submaxillaries; 24 gulars; four supraoculars; 6-7 supraciliaries; one very large preanal shield surrounded above and at the sides by two rows of smaller scales; 14 femoral pores on each side of the thigh, narrowly separated by 2 scales; 21 lamellae under fourth toe.

Mesalina bishnoi sp. nov.
Etymology: The specific epithet bishnoi (noun in apposition) honours the Bishnoi community of Rajasthan, India, an indigenous socio-ecological group renowned for their long-standing traditions of biodiversity conservation and sustainable coexistence with wildlife. Bishnoi cultural tenets, grounded in a deep reverence for nature, have contributed to the protection of numerous desert species and ecosystems in the Thar Desert since the 15th century. By naming this species Mesalina bishnoi, we recognise and celebrate the enduring environmental stewardship of the Bishnoi people and their contribution to the preservation of arid-zone herpetofauna.
