Remarks. This species closely resembles some species of Austroagallia but differs in the structure of the male genitalia. Specimens from Thiland and China have the aedeagal shaft more than 0.75 as long as the preatrial process, more or less straight and not as sinuate as in the Indian population.

This species has been bred on Achyranthes aspera L. ( Amaranthaceae ) in the labortory in Bangalore ( Viraktamath & Viraktamath 1981). Bindra (1973) collected this species on Amaranthus sp.
