New material. 1 male MNHN:Armen. Gebiet. Leder. Reitter [printed, black frame] .

Supplementary description. Belongs to the M. fasciata species group. Male from “Armen. Gebiet”. Total body length 3.2 mm. Forebody brown, head darker than pronotum. Elytra brown with triangular, pale yellow postbasal spot and broad, transverse band in postmedian half occupying most of the area, not interrupted at suture and leaving only elytral apex narrowly brown. Palps and antenna brown, five basal antennomeres somewhat paler. Legs yellowish­brown, tibiae yellow, distinctly paler than femora. Head about as long as wide, head base subtruncate to very broadly rounded, tempora subparallel, about the eye length, posterior temporal angles broadly rounded. Compound eye moderate, moderately protruding from lateral outline of head. Head dorsum moderately glossy, punctures circular to oval, moderate, rather deep, dense. Intervening spaces smooth, generally narrower than to as wide as punctures. Dorsal cranial setae whitish, moderately dense, appressed. Antenna moderately thickened in apical half. Terminal antennomere pointed, about 2.2× as long as penultimate antennomere, as long as combined length of antennomeres 9–10. Pronotum barely transverse, slightly narrower than head across eyes, moderately glossy, broadly rounded at anterior margin. Lateral margins strongly impressed in posterior half. Latero­basal pronotal fovea broad and deep, laterally with dense, whitish setation. Pronotal disc slightly convex in dorsal aspect. Pronotal punctures and setae similar to those on head, setae subdecumbent. Elytra about 1.7–1.8× as long as wide, laterally widened at midlength, dorsally barely convex. Humerus broadly rounded, not protruding.Apex of elytron modified, with a short, narrow, pointed denticle. Elytral disc moderately glossy, punctures somewhat smaller, in part denser than those on forebody. Intervening spaces generally as wide as to twice as wide as punctures, smooth, glossy. Elytral setae as those on pronotum, rather dense. Legs without modifications, tibial terminal spurs paired. Tergite VII subtruncate at posterior margin. Morphological sternite VII broadly rounded at posterior margin. Aedeagus as in Fig. 31C– D . Tegmen apex rounded, not projecting and not hooked; endophallic armature of numerous, acute, variably sized and shaped spinules.

Sexual dimorphism. Unknown.

Ecology. Unknown.

Distribution. Armenia, Turkey. Records from Croatia ( Reitter 1890; 1906) and Greece ( Krekich­Strassoldo 1929) are dubious and require further confirmation.

Chorotype. SW­Asiatic (1.13 SWA), considered Armeno­E­Anatolian endemic (3740.03 ARAN).
