Nemophora cassiterites belongs to the askoldella species-group (defined by Kozlov 1995 ); it differs from N. chionites ( Figs. 19, 20 ) by short PLB (slightly shorter than the vertical eye diameter) and from N. griseella ( Figs. 23, 24 ) and N. ischnodesma ( Figs. 25, 26 ) by the light base of the hindwing and by the silver-grey triangular costal spot adjacent to the outer border of the forewing fascia. Description ( Figs. 21, 22 , 81 ): see Kozlov (1995) . Distribution. India ( Assam , Meghalaya , Uttarakhand ). The latter record is based on a photograph (https:// www.inaturalist.org/observations/134009814).
