The recently established genus Rajburicoris Carpintero and Dellapé, 2008 is recorded from India for the first time based on a new species, R. keralanus Yamada, collected from Kerala State. This new species feeds on Liothrips karnyi, which infests black pepper leaves and forms leaf-curl galls. It differs from R. stysi Carpintero and Dellapé, 2008 by the labium reaching middle of mesosternum, the ostiolar peritreme weakly curving anteriorly before strongly recurving posteriorly at apex, and the omphalus basally widened and gradually more slender apicad. Biological information of the new species is provided. The genus is redefined based on the following autapomorphies: 1) pygophore with an irregular, small parameroid along left edge; 2) paramere strongly curved, very long, basally widened, and gradually narrowed toward apex; and 3) omphalus extremely long and circularly curved.
