Provisional Key to Schoenobiinae and separation of similar species
Forewing with broad pale costal streak sharply demarcated from dark subcostal streak D.mucronella (male and female)
(Pleurota bicostella has a similar forewing pattern but has 2 or 3 distinct dark discal spots)
Forewing with multiple small dark spots S.gigantella (male and some female)
Forewing with discrete oblique dark apical streak D.forficella (male and some female)
Male Chilo phragmitella looks similar to male D.forficella but lacks this oblique apical streak
Male S.gigantella may show a blurred oblique apical streak and have the forewing dots reduced making separation from D.forficella difficult >
Hindwing with postmedian and terminal bands of short dark streaks S.gigantella (male)
Hindwing white without cross-lines D.forficella
ws 41-46mm (fw 19-22mm), costa convex near apex S.gigantella (female)
ws 25-30mm (fw 12-14mm), costa convex near apex D.forficella (female)
ws 30-40mm (fw 14-19mm), costa concave near apex Chilo phragmitella (female)
