Cnaphalocrocis trebiusalis

The singular reference for the accurate IDing of this species is Francis Walker's holotype itself, though that male has its abdomen missing.

This is the only species in the complex that has a characteristic evenly very broad submarginal black band on both wings, and the additional characteristic that the males do not possess the androconial scale patches in the central subcostal region, and both sexes have 7-9 strigae on the costa. Also, the abdomen tip is broad and clearly distinguishable from the other common species.
This is one of the most common and widely distributed Cnaphalocrocis species throughout Asia, and arguably the most common species in India (with the possible exception of C. medinalis). The exceptionally wide distribution is highlighted in this reference, and in Hampson's Vol 4.

Strangely, GlobizPyraloidea for some reason doesn't synonymise this species with Epimima stereogona (Meyrick, 1886), though most old references do so, one of them even using the nomenclature Epimima trebiusalis.

This is often misidentified as other species on several web sources, like C. poeyalis, C. latimarginalis, etc., but the combination of features leaves no doubt that it is Walker's Botys trebiusalis.
