Ensina decisa Wollaston, 1858

Material examined. 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.
