Etymology. The species name refers to the pair of relatively large humps (hump in Latin: gibber) present on the anterior pit wall of T7.

Diagnosis. Distinguished from the preceding species by the much shorter glandular pouches and tubules, and by the presence of a pair of humps at the anterior pit wall.

Material studied. Type material. Holotype, 1♂, MOROCCO, Dayèt Iffer (NE Ifrane), 1600 m, 18.VIII.1984, leg. B. & H.Bohn (completely on two slides: Ma 14/6). (Coll. Bohn, ZSMC).

Additional material. MOROCCO. 14♂, 9♀, same data as holotype (slides: ♂, Ma 14/1,3–5,7–14,18; ♀, Ma 14/15–17) ; 4♂, 3♀, 1L, same locality and collectors as holotype, 16.VIII.1999 ( Ma 14b) ; 1♀, same locality and collectors as holotype, 22.IX.2000 (Ma 14c) ; 2♂, 5♀, Dayèt Hachlaf (E Ifrane), 1700 m, 19.VIII.1984, leg. B. & H.Bohn (slides: ♂, Ma 15/1,2); ex L : 1♂, W slope of Jbel Zalagh (near Fès), 500 m, 3.VI .1989, leg. B. & H.Bohn (slide: ♂, Ma 61a/1); ex L : 2♂, 8 km SW Ben-Slimane , 200 m, 25.V .1989, leg. B. & H.Bohn (slides: ♂, Ma 87/4,5); ex L : 1♂, Ben-Slimane , 270 m, 6.V .1997, leg. B. & H.Bohn (slide: ♂, Ma 88a/1). (Coll. Bohn, ZSMC) .

Description. Size. Male. Length of pronotum 1.58–1.74 (mean 1.63) mm, length of tegmina 2.53–2.78 (mean 2.65) mm. (N = 5/7). Female. Length of pronotum 1.80–1.93 (mean 1.85) mm, length of tegmina 2.20–2.39 (mean 2.28) mm. (N = 3/3).

Wings. Apex of tegmina in both sexes weakly concave ( Fig. 11F,G ); hindwings of variable shape, not broadening towards the apex ( Fig. 11H,I ).

Male abdomen. Tergites: Fig. 11A–E. T 6 as described under characters of the genus and the species group ( Fig. 5E ). T7. Pit size: up to size 4 ( Fig. 12F ); anterior pit wall (aw) below the strongly sclerotised area (sa) with a pair large humps (hu), further laterally followed by a respective excavation (ec, Figs. 11C , 12A,C,E ); stabilising bracelet (s) rather broad; posterior pit wall (pw) with a pair of well developed hemispherical bulges (bu) ( Figs. 11B,C , 12A–E ); glandular pouches (gp) shorter and mostly also narrower than in the preceding species, seldom surpassing the anterior border of T7 for more than the length of T7 at its lateral border ( Figs. 11B , 12A–F ); tubules, virtually stretched, not reaching the lateral border of T7. Genital hook with relatively normally shaped shaft, below the apical process not or only weakly bulged out ( Fig. 11J–L ).

Distribution. Morocco. So far only known from five localities at middle longitude, but rather distant in their latitudinal positions ( Fig. 37 ).
