Madeira : Calheta ( 1 female ) ; Encumeada ( 2 females , 4 males ) ; Folhadal ( 1 female ) ; Rabaçal ( 2 females , 1 male ) ; Porto Santo: Morenos ( 1 female ) ; Pico Branco ( 1 male ); Serra de Fora ( 3 females , 6 males ) . Desertas : Castanheira ( 6 females , 6 males ) ; Doca ( 1 male ) ; Ilhéu Chão ( 60 females , 126 males ). Remarks. One of the few representatives of its genus, E. decisa is endemic to Madeira and Canary archipelagos ( Smit 2006 ). It is distributed throughout Madeira archipelago from dry habitats to preserved laurel forests. Ensina decisa attacks Hypochaeris glabra in Madeira ( Smit 2006 ), but in the Canary Islands the host plants are unknown ( Merz 1992 ). Therefore, E. decisa might have a wider range of host plants. This species was found for the first time in Desertas, where it was recorded in high abundance on Ilhéu Chão.
