Thanks a lot Wojciech Adamowski
I reproduce again the couplet 117 on page 106 of BSI Flora of India
117a Basal lobe of wings produced upwards anteriorly into decurved
lobule.........I. edgeworthii
b. Basal lobe of wings not produced upwards anteriorly into decurved
lobule ......next 48 species
And description of I. edgeworthii on page 144 "Wings with a globular
dorsal auricle and a lobular structure towards sinus; basal lobes obovate,
6 x 5 mm; distal lobes oblong with ligulate apex, lobular structure oblong
, ca 6 x 2 mm "
Description of I. exilis which keys out along with rest 47 species "Wings
1-1.5 cm long; basal lobes ovate-triangular, 6-7 x 3-4 mm; distal lobes
elliptic-obovate, acutely pointed at apex, 7-10 x 5-7 mm; dorsal auricle
short, hooked"
