FIGURE 29 A–L. Main structures of L. beybienkoi.—A–F. Male tergites. A: T1–4; B: T5; C: T6; D: T7, with glandular pouches gp, pit pi (for more details see Fig. 30B); E,F: T8, (F) anterior part in more detail, rough cuticular structures along the anterior border only far laterally (arrow).—G,H. Left tegmen of male (G) and female (H).—I,J. Hindwing lobe l with part of metanotum mt of male (I) and female (J).—K,L. Male genital hook, with shaft sh, its apical process ap, velum ve, claw cl with crest cr, the latter with two strong antlerlike processes an.—Enlargements: Same scale for A–E, for G,H, and for I,J.— Identifications:A–F,H (Ty 3/1), G (Is 17/2), I (Is 16/1), J (Is 22/3), K (Bo 376, holotype), L (Is 14/2).

Abbreviations: ab, pb anterior, posterior border of pit opening; aw, pw anterior, posterior pit wall, the latter with a shallow bulge bu; gu gutter; gp glandular pouch; tf transversal folds; arrows in (A) indicate a gap in the sclerotisation of the pit bottom, present also on the right.—Identifications: A (Ty 1/1), B (Ty 3/1).

FIGURE 33 A–J. Left side of male T7 in the species of the beybienkoi-group. In all species the lateral angles of the pit opening are drawn out to a rather narrow gutter gu almost reaching the lateral border of the tergite. In L. graeca the anterior border of the pit opening continues laterally into a narrow edge ed converging with the gutter and approaching it closely near the lateral border of the tergite.—Further abbreviations: ab, pb anterior, posterior border of the pit opening; aw, pw anterior, posterior pit wall; gp glandular pouch; tu glandular tubule.—Identifications: A (Is 11/1), B (Ty 3/1), C (Is 21/1), D (Ty 1/1), E (Cy xx/1), F (Cy 18/1, holotype), G (Cy 21/1), H (Gr 1/5), I (Kr 23/2, holotype), J (Kr 10/5).
