Coll., gen, slide No.: AV7567 ♂ (OUMNH); 1 male, Khasia Hills, Assam / Doncaster private coll., Purch. 1927 (OUMNH); 1 male, 1 female, [Meghalaya, Khasi Hills] Khasia Hills, Assam, Nissary (NHMUK); 1 male, [Meghalaya, Khasi Hills] Cherrapunji, Sept. 1893, Assam / Rothschild Bequest, B.M. 1939-1, unique ID: NHMUK010916182 (NHMUK). Diagnosis. The forewing length is 13.5–14.0 mm in males and 15.5–16.0 mm in females. Teulisna khasiana sp. n. 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, T. khasiana sp. n. 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 T. khasiana sp. n. are most similar to T. obliquistria 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 T. obliquistria, the corpus bursae is saccate and its postero-ventral sclerotised protrusion is situated on the right side), and the larger appendix bursae. Distribution. The new species is currently known from Northeast India (Meghalaya). Etymology. The specific epithet is derived from the Khasi Hills, where the new species is found. The name is a noun in the nominative singular.
