Material examined Holotype, female (ICAR / NBAIR / P4829), INDIA: Karnataka: Bengaluru, Jarakabande Kaval, 13.124°N, 77.548°E, ca 920 m, MT, 23 January 2015. Etymology The specific name ‘stupa’ refers to the arched submedian carina of the frontal depression which resembles the hemispherical stupas or reliquaries containing the remains of Buddhist monks and nuns or artefacts associated with them. The name is treated as an adjective. Diagnosis Hadronotus stupa sp. n. is similar to H. taraka sp. n. but differs from it in the following character states: In H. stupa central keel is short, at most 0.1× length of frontal depression and mesoscutum and mesoscutellum with longitudinal carinae, while in H. taraka central keel is half the length of frontal depression and mesoscutum and mesoscutellum are without longitudinal carinae.
