- Abdomen with narrow black bands on posterior margin of each of tergites 1–4; scutum with pair of large L-shaped presutural black marks.......................................................................................... 4

2. Thorax only with pair of presutural black spots, other parts entirely yellow ( Fig. 3 )................... I. consors (Walker)

- Thorax in addition to presutural black spots, also with black spots on pleuron or postsuturally on scutum................ 3
