Nymph. Unknown.

Host plant. Teline canariensis .

Distribution. Canary Islands: Tenerife.

Notes. Known from only one location despite extensive sampling of the relatively widespread host plant. This species was discovered in the laurisilva habitat of the Anaga peninsula, occurring sympatrically with A. pileolata , A. menceyata sp. n. and A. diluta , and was the most common species in this particular location.

Etymology. Named for the Canary Islands and for the host plant, Teline canariensis .

Type material. Holotype W (slide mounted), Canary Islands, Tenerife: Anaga , E of Pico del Inglés, 28°32∞15◊N, 16°16∞30◊W, ca 960 m, 25 April 1998 ( BMNH) . Paratypes 12 W, 10 X, as for holotype ( BMNH) . 1 W, 1 X, as for holotype ( DZUL) . 1 W, 1 X, as for holotype ( NHMB) .
