Fifth instar chaetotaxy. Head setae simple; ocular seta simple or narrowly capitate, dark, conspicuous; primary and secondary post-ocular setae distinctly capitate. Dorsal thoracic setae short simple and long, stout capitate. Forewing pad macrosetae three to seven, distinctly capitate, marginal, proximal seta distinctly capitate or rarely indistinct; hindwing pad macrosetae two or three, simple or distinctly capitate, marginal (one or two apical, one proximal), proximal seta simple or distinctly capitate, apical seta paired with small capitate or small simple seta; simple microsetae scattered on the wing pad surfaces. Dorsal abdominal pre-caudal macrosetae present on anterior tergites, long capitate, caudal plate macrosetae absent; sectasetae four pairs; marginal abdominal setae (other than sectasetae) three pairs, distinctly capitate; pleurite setae paired simple or paired capitate and simple. Legs with simple setae only.

Host plant. Genista segonnei .

Distribution. Continental: Morocco.

Notes. Occurs in the Anti-Atlas mountains. The host plant is locally common in isolated populations, but this species was not common in either of the locations sampled.

Etymology. Named for the Berber culture of the Anti-Atlas region.

Type material. Holotype W (slide mounted), Morocco: Anti-Atlas, SE slopes of Jbel Lekst , below Tagudicht Aitsmaon, 29°42∞N, 9°05∞W, ca 1500 m, 3 May 1999 ( BMNH) . Paratypes 7 W, 2 X, 4 nymphs, as for holotype ( BMNH). 1 W, 1 X, 4 nymphs, as for holotype ( NHMB) .
