Viraktamath and Viraktamath (1981) have adequately described the species. Only illustrations of the male genitalia are given to help identification.

Material examined. INDIA: HOLOTYPE ♂, Karnataka: Devarayadurga , x.1917, T.V. Campbell, Brit. Mus. 1928-508 ( BMNH) . PARATYPES: 1 ♀, same data as holotype ( BMNH) , 1 ♂, Nandi Hills , 19.xii.1974, C.A.Viraktamath ( UASB) . Additional material: India: Tamil Nadu : 12 ♂, 13 ♀, 1 nymph, Burliyar , 22–23. x.1975, ex Justicia betonica , 2 ♂, 2 ♀, Kallar , 22–23.x.1975 C.A. Viraktamath ( UASB) . SRI LANKA: SYNTYPE ♂, Ceylon, Peradeniya , Juni [1]902, Dr Melichar ( MMB) .

Remarks. The specimens from Burliyar and Kallar are larger than the types (males 3.4–3.7 mm long, females 3.43–4.0 mm long) and are much darker, especially the forewings, where the veins are dark brown to piceous and the clavus is either dark brown or black. The synonymy was based on an examination of the types of both species. The species was collected on Justicea betonica L. ( Acanthaceae ) in nature and was successfully bred on Achyranthes aspera L. ( Amaranthaceae ) in the laboratory ( Viraktamath & Viraktamath 1981).
