Material examined. INDIA: Tamil Nadu: Lectotype ♀, “Kodaikanal, S. India, Campbell” “H4 4 ” “K.K., 4.14[handwritten on reverse of card carrying the specimen]” “ Traiguma verticalis Dist. Type” ( BMNH). INDIA: Tamil Nadu: 4 ♁, 6 ♀, 1 nymph, Kodaikanal , 2133m, 8.v.1980, A.R.V. Kumar Coll.; 3 ♁, 3 ♀, 3 nymphs, Shambhaganur,1800m, 8.v.1980, A.R.V. Kumar Coll. ( UASB).
