The forewing length is 13.5–14.0 mm in males and 15.5–16.0 mm in females. <i>Teulisna khasiana</i> <b>sp. n.</b> is externally different from other similar congeners in the strongly elongate forewing with a short costal protrusion and reddish-brown ground colour. In the male genitalia, <i>T. khasiana</i> <b>sp. n.</b> is distinguished from similar species in the lack of the pseudoampulla and the bilobate vesica with a medial-lateral lobe bearing a vesica ejaculatorius, three short subdiverticula of various shapes, and an elongate and narrow tubular subdiverticulum bearing a spearhead-shaped terminal cornutus. The distal lobe is represented by the broad and tubular distal diverticulum bearing a robust spike-shaped terminal cornutus. The female genitalia of <i>T. khasiana</i> <b>sp. n.</b> are most similar to <i>T. obliquistria</i> but differ clearly in the markedly narrower ductus bursae, the anteriorly tapered corpus bursae with a postero-ventral sclerotised protrusion situated on the left side (whereas in <i>T. obliquistria</i>, the corpus bursae is saccate and its postero-ventral sclerotised protrusion is situated on the right side), and the larger appendix bursae.</p><p><b>Distribution</b>. The new species is currently known from Northeast India (Meghalaya).</p><p><b>Etymology</b>. The specific epithet is derived from the Khasi Hills, where the new species is found. The name is a noun in the nominative singular.</p>
