Distant (1916: 232) misidentified females of Igerna violacea from Kodaikanal and Nilgiri Hills as Nehela bimaculicollis (Stål) , a species that does not occur outside Africa. I. violacea shares the fused connective with I. quinlani and I. keyae . Coloration and branching of the aedeagal processes and anal collar process vary as shown in figures 369, 370, 372, 374, 377–379.
