Abstract

Eight specimens of Prionobutis microps, ranging from 59.74 to 121.51 mm in standard length, were collected from multiple localities in West Bengal, eastern India. These specimens represent the first confirmed record of the species for India. The morphological characteristics of the specimens are described in detail, with Prionobutis microps characterised by equal-sized upper and lower jaws, a non-protruding chin with small, fleshy, barbel-like papillae, and both the mottled pectoral-fin base and the rays lacking distinct spots. While previous reports suggested the species' presence in eastern India, they remained unverified. This study confirms its occurrence in India, resolving uncertainties about the distribution of the species and extending its known range approximately 1600 km westward from Thailand.
