Mecinus janthinus Germar 1821
No full textMecinus janthinus group Diagnosis. Elytra distinctly elongate. Dorsal integument black or blue, sometimes with metallic reflections. Flagellum characterized by at least six rounds. Spermatheca with subspherical body including ramus. Remarks and comparative notes. The shape of the body together with the colour of the dorsal integument are characters which this group shares with that of M. heydenii. These two groups include the unique species of Mecinus not living on Plantago. The species related to M. janthinus are distinguishable from those related to M. heydenii by the less curved rostrum in lateral view, the shape of the penis, the distinctly longer flagellum and the completely unusual shape of the spermatheca that is reminiscent of the Cionini.Published as part of Caldara, Roberto & Fogato, Valter, 2013, Systematics of the weevil genus Mecinus Germar, 1821 (Coleoptera: Curculionidae).

Mecinus janthiniformis Tosevski & Caldara 2011
No full text40. Mecinus janthiniformis Toševski & Caldara Mecinus janthiniformis Toševski & Caldara, 2011: 750. Type locality. Streževo (Macedonia). Type series. This species was described from 43 specimens from Hungary, Serbia, Macedonia and Bulgaria (for detailed data see Toševski et al. 2011). Redescription. As in M. janthinus, except: body generally larger (length 3.2–6.0 mm); apical part of the rostrum in female in lateral view more curved (Fig. 89); punctures of pronotum slightly smaller, more densely adpressed; scales of elytral interstriae denser, arranged in two rows on part of several interstriae. Body of penis with sides slightly more abruptly narrowed in subapical part, towards apex ending in form of subtruncate tip (Fig. 139). Remarks and comparative notes. The separation of M. janthiniformis from M. janthinus at species level was clearly shown based on very careful biological and genetic studies (Toševski et al. 2011). Unfortunately these two species are cryptic and easy identification is only possible by collecting the specimens together with its host plant. However the subtle differences between these two taxa listed above allow for the separation of almost all museum specimens from south-eastern Europe, where they are usually sympathric. Biological notes. The host plants of M. janthiniformis are Linaria genistifolia (L.) Miller and L. dalmatica (L.) Miller. Adults emerge in early April and feed intensively on the apical leaves and the apical part of new shoots. Copulation takes place in April and first oviposition can be observed at the beginning of May. The egg-laying period lasts from May until mid-July. In contrast to M. janthinus, M. janthiniformis females oviposit either on the upper part of the central stem, or on the basal part of lateral flowering branches. As a result of oviposition and larval development, the plant induces a slightly elongated gall-like alternation in which larval development will take place inside a relatively short larval chamber (about 1 cm long). During development, larvae continuously feed on the gall-like tissue from the chamber walls. Similar to M. janthinus, M. janthiniformis is heavily parasitized by the endoparasitic wasp Entedon sparetus, which can reduce population densities of this weevil by more than 80% (Toševski et al. 2011). Distribution. Hungary, Romania, Serbia, Macedonia, Bulgaria, Greece, Turkey. A small number of adults have been collected on L. dalmatica in Macedonia and introduced to North America in 1992–1993 as M. janthinus (I. Toševski and A. Gassmann unpublished data; Wilson et al. 2005). Non-type specimens examined. HUNGARY: Mt. Villányi, Mariágyüd, 28.V.2006, Škoda leg. (1, JKCH). ROMANIA: Comana Vlasca, Montandon leg. (10, MSNM).

This species was described from specimens collected by Pic in the Sahara. We examined one of them (Pic's collection, MNHN) labelled “Tiout / 69 / Mis. Ent. IV n°7(96) p. 96 / Mecinus setulosus m. type Pic xx [sic] / type / M. setulosus Pic / Reitter vid.” (male, lectotype here designated). Redescription. Male. Length 2.1 mm. Body: long, cylindrical, slender. Rostrum: black, moderately long (Rl/ Pl 0.92); in lateral view weakly curved, weakly narrowed in apical half (Fig. 89); in dorsal view with sides weakly convergent from base to apex, with hardly visible scrobes, distinctly striate-punctured in basal two thirds then smooth and shining, in basal half with scales somewhat dense, white, moderately long (l/w 3–5), subelliptical, recumbent. Head: frons slightly wider than rostrum at base, without fovea; eyes nearly flat. Antennae: dark brown, inserted just in front of middle of rostrum; scape long, 6.0x longer than wide; funicle segment 1 3.0x longer than wide, slightly stouter and 1.5x longer than segment 2, which is 1.3x longer than wide, segments 3–5 gradually more transverse; club long, oval, with segment 1 about as pubescent as others. Pronotum: black, densely and slightly irregularly punctured, intervals between punctures narrow, rugose, moderately shining, moderately visible between scales somewhat dense, white, subelliptical to lanceolate, recumbent; moderately transverse (Pw/Pl 1.43), with weakly rounded sides, widest at middle, with weakly prominent apical constriction, moderately convex. Elytra: black; long (El/Ew 1.75), weakly concave at base, slightly wider than pronotum (Ew/Pw 1.08), with parallel sides, moderately convex on disc; interstriae clearly visible between, recumbent to subrecumbent, sparse, white, moderately long (0.50–0.75x as long as width of interstria; l/w 3–5), subelliptical to lanceolate scales, arranged in a somewhat regular row; striae clearly visible, as wide as half of interstria, with a row of white scales, shorter and narrower than those of interstriae. Legs: moderately slender, with recumbent to subrecumbent, somewhat dense, whitish, seta-like scales, which are distinctly shorter than width of tibia; femora black, profemora with big sharp tooth, mesofemora with small tooth, metafemora unarmed; tibiae blackish, moderately slender; protibiae with apical part of ventral surface weakly directed outward; unci black, moderately stout, all equal in length and size; tarsi reddish brown, tarsomere 1 twice as long as wide, tarsomere 2 1.5x longer than wide, tarsomere 3 bilobed, distinctly wider than tarsomere 2, onychium slightly shorter than tarsomeres 1–3 taken together; claws blackish brown, equal in length, fused in basal half. Venter: metasternum moderately visible between somewhat dense, white, moderately long, subelliptical scales; mesothoracic epimera and meso- and metathoracic episterna with moderately dense, white, moderately long, subelliptical scales; abdomen with dense and somewhat regular punctures, which are clearly visible between moderately dense, whitish, moderately long to long, subelliptical to seta-like scales; ventrites length ratio 1–2/3–4 2.00. Penis: as in M. janthinus (Fig. 140). Female. Unknown. Variability. We examined only the lectotype of this species. Remarks and comparative notes. Based only on study of the lectotype, since we did not find other specimens of this taxon, M. setulosus appears to be mainly related to M. barbarus, with which it shares the shape of the penis. It differs distinctly from this species in the pattern of the dorsal vestiture which is composed of distinctly wider scales (on pronotum and elytral interstriae only 3–4x vs. 8–10x longer than wide) and the shorter elytra.

Mecinus kaemmereri Wagner 1927
No full text39. Mecinus kaemmereri Wagner Figs 88, 139 Mecinus kaemmereri Wagner, 1927: 96. Toševski et al., 2011: 747. Type locality. Monti Rossi (Nicolosi, Sicily). Type series. Wagner described M. kaemmereri from specimens collected on Monti Rossi near Nicolosi (Sicily) on Linaria purpurea (L.) Mill., and reported that this new species is very closely related to M. janthinus from which it differs by its bigger size, the more curved and longer rostrum in both sexes and antennae with stouter funicle and longer club. At NHMB (Frey's collection) we examined a syntype labelled: “ Sicilia, Mti. Rossi b., Nicolosi a. Aetna, V.26 / Mecinus Kämmereri, Wagner det.”. Redescription. As in M. janthinus, except: body generally larger (length 3.3–6.0 mm), rostrum longer (Rl/Pl male 0.89–1.02; female 1.10–1.20) (Fig. 88), in female with apical half less sculptured. Variability. The rostrum varies somewhat in curvature in female, with the typical specimen having the rostrum distinctly more curved than the other examined specimens. Remarks and comparative notes. It differs from M. janthinus and M. janthiniformis by the shape of the rostrum, which is longer, less sculptured and nearly straight in lateral view in its apical half especially in the female. Moreover, M. kaemmereri is usually larger than M. janthinus, to which it is more closely phylogenetically related than M. janthiniformis based on a molecular study (Toševski et al. 2011) and is probably a vicariant in Calabria and Sicily. Therefore the hypothesis by Toševski et al. (2011) that M. kaemmereri might be considered a subspecies of M. janthinus appears reasonable. Biological notes. This species feeds only on Linaria purpurea (L.) Mill. (C. Baviera pers. obs.), which is an endemic plant of central and southern Italy and Sicily. Distribution. Italy (Calabria, Sicily).

Type series. This species was described from one male and one female collected in Algeria without more precise indications. We examined the male (MNHN) labelled “Boghari, Algérie / 1 ♀ [in] coll. Reiche / type / Type” (lectotype here designated). Redescription. Male. Length 2.6 mm. Body: long, subcylindrical, moderately slender (Fig. 23). Rostrum: reddish, moderately long (Rl/Pl 0.82), subcylindrical; in lateral view weakly curved, weakly narrowed at apex (as in M. tychioides, fig. 54); in dorsal view with subparallel sides, with hardly visible scrobes, moderately striatepunctured to apex, in basal three quarters with subrecumbent to suberect, somewhat dense, whitish and light brown, long (l/w 6–8), seta-like scales. Head: frons weakly narrower than rostrum at base, without fovea; eyes flat. Antennae: reddish, inserted at middle of rostrum; scape moderately long, 5.0x longer than wide; funicle slightly longer than scape, segment 1 3.0x longer than wide, slightly stouter and 1.5x longer than segment 2, which is twice as long as wide, segments 3 and 4 about as long as wide, segment 5 transverse; club moderately long, oval, segment 1 almost glabrous. Pronotum: reddish, irregularly punctured, intervals between punctures opaque, smooth, partly slightly wider than punctures, moderately visible between recumbent to subrecumbent, somewhat dense, white and light brown, long to very long (l/w 8–14), seta-like scales, white scales denser at sides where forming a distinct vitta; weakly transverse (Pw/Pl 1.16), with moderately rounded sides, widest just before middle, with moderately prominent apical constriction, weakly convex. Elytra: reddish; long (El/Ew 1.60), subrectangular, at base moderately concave, somewhat wider than pronotum (Ew/Pw 1.33), with subparallel sides, weakly convex on disc; interstriae hardly visible between recumbent to suberect (especially at apex), somewhat dense, white and light brown, long to very long (1.0–1.5x as long as width of interstria; l/w 8–14), seta-like scales, which are confusedly arranged in various irregular rows, white scales more numerous along interstria 1 and sides; striae hardly visible, as wide as half of interstria, with a row of scales similar to those covering interstriae. Legs: moderately slender, with recumbent to suberect, moderately dense, whitish, seta-like scales, which are slightly shorter than width of tibia; femora reddish, with small tooth; tibiae reddish, moderately slender; protibiae with apical part of ventral surface weakly directed outward; unci blackish, moderately stout, all equal in length; tarsi reddish, tarsomere 1 twice as long as wide, tarsomere 2 1.2x longer than wide, tarsomere 3 bilobed and moderately wider than tarsomere 2, onychium slightly longer than tarsomeres 1–3 taken together; claws black, equal in length, fused in basal half. Venter: metasternum reddish, clearly visible between recumbent to subrecumbent, sparse, whitish, long, hair-like scales; mesothoracic epimera and meso- and metathoracic episterna covered with somewhat dense, whitish, long, seta-like scales; abdomen reddish, with moderately dense and regular punctures, with intervals between punctures wider than punctures, which are clearly visible between recumbent to subrecumbent, sparse, whitish, long, hair-like scales; ventrites length ratio 1–2/3–4 2,05. Penis: fig. 125. Female. As in male except rostrum distinctly longer (Rl/Pl 1.15), cylindrical, in lateral view slightly more curved (Fig. 64), antennae inserted just before middle of rostrum. Sternite 8: fig. 147. Spermatheca: fig. 163. Variability. Length 2.0– 2.9 mm, average 2.6 mm. Sometimes the curvature of the sides and the convexity of the pronotum are slightly more pronounced than as described above. Remarks and comparative notes. This species is usually labelled as M. longulus in museum collections. Superficially, M. reichei seems similar to species of Tychius Germar, 1817 with long, rectangular elytra that are almost flattened on the disc and with brownish dorsal vestiture with white vittae on interstria 1 and at the sides. Due to these features, M. reichei is easily distinguishable from other species of Mecinus, although small specimens show feeble similarities with M. paratychioides, which is, however, a species characterized by the unusual shape of the antennal club and tarsomere 3 being as wide as tarsomere 2. It also differs from M. tychioides, which has shorter elytra with sparser vestiture Biological notes. One specimen collected near Aín Sefra is reported to have emerged from Launaea arborescens (Batt.) Murb. (Sama det.), which is a plant belonging to the Asteraceae, a family which has never been reported as a host of other species of Mecinus. Therefore this datum needs confirmation. Distribution.
