Henckelia arupii, a new species discovered from Arunachal Pradesh, India, is described and illustrated. The new species is superficially similar to Henckelia adenocalyx and three other Northeast Indian species in habit, in the broadly ovate foliaceous bracts covering the flower buds, in the parallel-convergent venation of the bracts and in the infundibuliform corolla. However, it differs in having cymes reduced to solitary flowers, a campanulate, narrowly pleated calyx and lanceolate to elliptic revolute calyx segments. A detailed description and photographic illustration of the morphological characters is presented. So far, Henckelia arupii is only known from the type locality.
