Supplementary description. Belongs to the M. terminata species group. Male lectotype. Total body length 3.1 mm. Dorsum and venter entirely black to dark black­brown. Antennomeres 1–7 yellowish to yellowish­brown, remaining antennomeres dark. Palps and legs yellowish­brown, tibiae moderately paler than femora. Head barely longer than wide, basal margin broadly rounded in arc with posterior temporal angles. Compound eye large, moderately protruding from lateral outline of head. Head dorsum glossy, punctures moderate, rather deep, elongate. Intervening spaces smooth, generally as wide as to twice as wide as punctures. Dorsal cranial setae yellowish, moderately dense and long, appressed. Antenna slightly thickened in apical third. Terminal antennomere moderately elongate, apically acutely pointed, about twice as long as penultimate antennomere and almost as long as combined length of antennomeres 9–10. Pronotum 1.1–1.2× as long as wide, narrower than head across eyes, subopaque to slightly glossy, rounded at anterior margin. Lateral margins moderately converging in posterior half. Latero­basal pronotal fovea moderately broad and deep, with curved, whitish setation. Pronotal disc flattened in dorsal aspect. Pronotal punctures somewhat denser than those on head, intervening spaces generally as wide as punctures, glossy. Pronotal setae whitish to yellowish, moderately long and dense, appressed. Elytra about 1.6–1.8× as long as wide, laterally subparallel, slightly widened postmedium, dorsally flattened. Humerus broadly rounded, not protruding. Apex of elytron modified, channel of gland forming oval opening and acute, triangular denticle. Elytral disc moderately glossy, punctures moderate, dense. Intervening spaces as wide as to twice as wide as punctures, smooth, glossy. Elytral setae whitish, fine, moderately long and dense, appressed. Legs without modifications, tibial terminal spurs paired. Tergite VII subtruncate at posterior margin. Morphological sternite VII broadly rounded at posterior margin, medially shortly notched. Aedeagus as in Fig. 24E–E .Tegmen apex hooked, endophallic armature with a pair of strong, short, C­like shaped spines, a bunch of dense, narrow, subparallel spines and numerous subtriangular spinules.

Sexual dimorphism. Female somewhat larger than male, elytra less slender, elytral apex with moderate, acute triangular denticle which is larger than that of male.

Ecology. Unknown.

Distribution. Bulgaria, Greece (incl. Ionian Islands – Kefalonia Island), European and Asian Turkey. Records from Kríti (Crete) Island by Uhmann (1985, 1989) require confirmation. I had no opportunity to study any Turkish specimen of this species.

Chorotype. E­Mediterranean (3.03 EME), considered restricted to the E European part of it and, possible, to W Turkey.
