description
Description. Size. Male. Length of pronotum 1.5 mm, length of tegmina 3 mm. Wings. Male. Tegmina: Long, almost reaching the end of the abdomen, apex obliquely cut, with broadly rounded corners (Fig. 22 G). Hindwings: broadening towards apically, apex with a very weak median concavity (Fig. 21 J). Male abdomen. Tergites. Fig. 22 A – F. T 6 as in L. trivittata mesally with relatively strongly produced anterior border and laterally with a pair of small deepenings, but differing by the absence of a transversal ridge and the distribution of large spatular bristles extending till near to the anterior border of the tergite (anterior bristle stripe, Figs. 1 C, 2 C, 3 A), anterior deepening (ad) formed as a funnellike hole (Fig. 5 B), posterior deepening (pd) similar as in L. trivittata (Fig. 4 F); for more details see under characters of the genus. T 7. Pit size: moderately long, size 3 (Fig. 22 E, F). Anterior pit wall (aw) below the strongly sclerotised area sa with a pair of rather shallow excavations (ec, Fig. 22 F); stabilising bracelet relatively broad (s, not visible in Fig. 22 F), other structures of the anterior pit wall not well visible. Posterior pit wall (pw) with a pair of well developed hemispherical bulges (bu) (Fig. 22 F). Glandular pouches (gp) long, surpassing the anterior border of the tergite for more than the length of T 7 at its lateral border (Fig. 22 E); length of tubules not analysable. Genital hook not saved. Female. Not known.

diagnosis
Diagnosis. In the male sex from L. trivittata distinguished by the different structure of T 6 — missing a transversal ridge, but having an anterior bristle stripe (Fig. 1 C) — and by the obliquely cut tegmina (Fig. 22 G).
discussion
Remarks. The type specimen was found in a mixture of specimens from two closely adjacent localities containing also several specimens of L. trivittata. It is, therefore, not clear whether the two species were found at the same locality. III. The beybienkoi- species group Characters (all group specific, differing from those of the other two species groups) Male T 6. Strongly specialised: Anterior border mesally not produced, but tergite as a whole curved towards anteriorly, with the shortest length among the three species groups (Figs 1 D, 6 B – D); additionally well characterised by the unique bristle pattern and the so-called “ draining system ” consisting of the specialised deepenings and trenches connecting them (Figs. 2 D – H, 3 B, 4 B – D, 5 A, C, D); for more details see description under genus characters. Wings. Male tegmina fairly reaching up to the abdominal end, apex symmetrically rounded (Figs. 23 F; 25 G; 29 G; 31 G); hindwings in both sexes as in the trivittata - group broadening towards apically, apex usually with a shallow concavity (Figs 23 H, I; 25 I, J; 29 I, J; 31 I, J). Tergite 1 – 5 covered only with very short bristles having a pointed tip (Fig. 36 D). Orientation of T 7 pit. Pit with an inclination of about 45 ° descending from the opening towards ventroposteriorly. Pit opening at the lateral angles elongated to a narrow and low gutter almost reaching the lateral borders of T 7 (gu in Fig. 33 A – J). Anterior pit wall without strongly sclerotised and sculptured cuticle along the upper margin, stronger sclerotisation restricted to the upper edge of the wall, appearing as a thin dark contour line (ab in Figs. 24 A; 27 A; 30 B; 32 D). Window frame bordering the windows of the anterior pit wall below the arc on both sides with a number of closely approached transversal folds (tf in Figs. 24 C; 27 A, B; 30 A; 32 G). Anterior border of T 8 mesally weakly convex (Fig. 25 E, F), straight (Fig. 23 D, E), or shallowly concave (Figs. 29 E, F; 31 E, F), only far laterally with rough cuticle. Genital hook with an unusually broad shaft, diameter at middle length equals about a half of the total length (Fig. 23 J, K), part of the species moreover with huge crest and two antler processes (Figs. 25 K, L; 29 K, L; 31 K, L). Colouration of tegmina. Dispersed bristles of the lightly coloured area between the dark longitudinal stripes arising in the center of a dark dot (Figs. 24 F, G; 24 H, I; 26 A, B; 32 A, B). Colouration of male and female tegites. Males very lightly coloured, T 1 – 5 at most with a relatively small mesal patch, sometimes only present on the more anterior tergites (Figs. 23 A; 25 A, B; 29 A, B; 31 A, B). Females much darker coloured, with 3 – 7 patches per tergite (Fig. 35 E – H). — Mesal patch of T 1 in female broadly T-shaped (Fig. 35 E – H). [Pre-ridge area not considered; for a more detailed description see under characters of the genus.] Colouration of meso- and metanotum in larvae of medium and higher age. With three longitudinal dark stripes as in the preceding species groups, but both nota additionally with a pair of dark patches in between (Fig. 36 B). Additional features, applying to all species of the group: Glandular pouches long, considerably surpassing the anterior border of T 7; glandular tubules very short, virtually stretched not reaching the lateral borders of the tergite; the structures of the pit are also very similar in all species of the group. In the following descriptions the various structures are usually only mentioned and the figures cited on which they are well visible, but not further described.
distribution
Distribution. Only known from the type locality in Eastern Algeria.
etymology
Etymology. The species is named after the Algerian scientist Wafa Habbachi (Université Badji Mokhtar in Annaba, Algeria) who had together with his collaborator N. Aberkane collected this species during their studies about the insect fauna of the National Park of Chelia.
