Mecinus aubei Desbrochers des Loges, 1893: 58 View in CoL . Reitter, 1907: 9. Mimeur, 1949: 113. Hoffmann 1958: 1273, note.

Type locality. Bône [= Annaba] ( Algeria).

Type series. This species was described from specimens collected in Algeria (Bône, Constantine) of Desbrochers des Loges' and Pic's collections. We examined two syntypes ( Pic's collection, MNHN) labelled respectively “Bône, avril 54 / B115 / 84 / Desbr. vid. type! / type / Aubei m. type / TYPE” (male, lectotype here designated) and “Bône, janv. 58 / B115 / Mecinus Aubei Desbr. type” (female, paralectotype) .

Redescription. Male. Length 2.6 mm. Body: long, cylindrical, slender ( Fig. 42 View FIGURES 37–42 ). Rostrum: black, moderately long (Rl/Pl 0.82); in lateral view distinctly and abruptly curved in basal half, weakly narrowed in apical half (as in M. dorsalis , fig. 95); in dorsal view with subparallel sides, weakly widened at antennal insertion, with moderately visible scrobes, weakly striate-punctured, smooth, shining, without puntures along midline, in basal half with recumbent, sparse, white, moderately long (l/w 3–6), seta-like scales. Head: frons as wide as rostrum at base, with moderately deep fovea; eyes nearly flat, with posterior margin abruptly raised. Antennae: inserted at middle of rostrum, completely black; scape moderately short, 4.0x longer than wide; funicle distinctly longer than scape, segment 1 twice as long as wide, slightly stouter and slightly longer than segment 2, which is twice as long as wide, segments 3 and 4 as long as wide, segment 5 transverse; club long, oval, segment 1 about as pubescent as others. Pronotun black with bronze reflexions, with dense and regular punctures, intervals between punctures smooth and shining, clearly visible between recumbent, sparse, white and brownish grey, long (l/w 5–8), seta-like scales, the white scales more numerous along midline and sides; weakly transverse (Pw/Pl 1.14), with moderately rounded sides, with moderately prominent apical constriction, widest at middle, moderately convex. Elytra: black with distinct bronze reflexions, shining; very long (El/Ew 1.85), at base moderately concave, with parallel sides, slightly wider than pronotum (Ew/Pw 1.10), moderately convex on disc; interstriae clearly visible between recumbent to suberect, sparse, white, long (as long as width of interstria; l/w 6–9), seta-like scales, arranged in a single regular row; striae clearly visible, one third narrower than interstriae, with a row of scales slightly thinner than those of interstriae. Legs: moderately slender, with recumbent to suberect, sparse, whitish, seta-like scales, which are distinctly shorter than width of tibia; femora black, pro- and mesofemora with stout tooth, metafemora with smaller tooth; tibiae blackish brown, moderately slender; protibiae with apical part of ventral surface weakly directed outward; unci blackish, stout, all equal in length; tarsi blackish brown, tarsomere 1 1.5x longer than wide, tarsomere 2 about as long as wide, tarsomere 3 distinctly bilobed and distinctly wider than tarsomere 2, onychium shorter than tarsomeres 1–3 taken together; claws brown, fused at base, asymmetrical, with one claw distinctly smaller and about two thirds shorter than other claw. Venter: metasternum black, clearly visible between sparse, whitish, long, seta-like scales; mesothoracic epimera and meso- and metathoracic episterna with sparse, white, narrow, seta-like scales, and wide, fringed scales; abdomen black with bronze reflexions, with dense and somewhat regular punctures, which are clearly visible between sparse, whitish, long, seta-like scales; ventrites length ratio 1– 2/3–4 1.67. Penis: fig. 142.

Female. As in male except rostrum slightly longer (Rl/Pl 0.87) (as in M. dorsalis , fig. 96), less punctured, antennae inserted just before middle, femora unarmed. Sternite 8 and spermatheca: as in M. heydenii ( Figs 156 View FIGURES 144–156 and 170 View FIGURES 157–171 ).

Variability. Length 2.3–3.1 mm. The frontal fovea is more or less evident, as is the pronotal apical constriction. The antennae and tibiae vary in colour from reddish brown to blackish brown. The sides of the pronotum vary slightly in curvature.

Remarks and comparative notes. This species is distinguishable from the other species of its group by the more elongate and narrower elytra, whose integument are black, shining, with distinct, bronze reflexions.

Biological notes. In Morocco larvae of this species induce big galls in the stems of Linaria gharbensis Bat. & Pit. , where they pupate and where this species seems to coinhabit with Rhinusa brondelii (H. Brisout de Barneville, 1862) ( Mimeur 1949) .

Distribution. Southern Portugal, central and southern Spain, southern France, northern Africa, Syria.
