Diagnosis. Larva. Second segment of labial palp wide and short ( Fig. 24 ). Abdominal segment III with poorly expressed paired submedian tubercles ( Fig. 23 ), with smoothly rounded lateral margins ( Fig. 1 ). Ventral lobe of tergalius II with 3 narrow side processes on costal branch ( Fig. 2 ); ventral lobe of tergalius III with 3 side processes on costal branch and 4 side processes on anal branch ( Fig. 3 ); ventral lobe of tergalius IV with 2 side processes on costal branch and 3 side processes on anal branch ( Fig. 4 ).

Alate stages. Hind wing with costal projection directed anteriorly-distally ( Fig. 29 ). Abdomen with black hypodermal maculae occupying most part of terga and sterna; median area of sterna with black maculae along nerve cord; process of styliger entirely black ( Fig. 22 ) and wider than penis ( Fig. 28 ).

Distribution. Southern India ( Selvakumar et al. 2014; this study).
