Supplementary description. Belongs to the M. olivacea species group. Male syntype. Forebody dark brown, pronotum somewhat reddish­brown. Elytra dark brown with paired, large, irregularly triangular posthumeral and trapezoid postmedian yellow spots. Antennomeres 1–6 yellow, remaining antennomeres brownish. Palps yellowish­brown, terminal maxillary palpomere darker than preceding antennomeres. Legs yellowish, femora darker than tibiae. Head about 1.2× as long as wide, head base subtruncate, tempora subparallel, posterior temporal angles rounded. Compound eye moderate, about as long as tempus, strongly protruding from lateral outline of head. Head dorsum moderately glossy, punctures small, rather shallow, dense. Intervening spaces smooth, generally narrower than to as wide as punctures. Dorsal cranial setae yellowish, 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 longer than wide, slightly narrower than head across eyes, moderately glossy, broadly rounded at anterior margin. Lateral margins moderately constricted in posterior half. Pronotal disc barely convex in dorsal aspect. Pronotal punctures generally smaller than those on head, intervening spaces about twice as wide as punctures, glossy. Pronotal setae similar to those on head, rather long. Elytra about 1.6× as long as wide, laterally subparallel, dorsally flattened. Humerus broadly rounded, not protruding. Elytral disc slightly glossy, punctures dense. Intervening spaces generally twice as wide as punctures, smooth. Apex of elytron modified, broadly triangularly projected at opening of gland channel. Elytral setae yellowish, appressed, directed obliquely laterally along suture on anterior two thirds of elytron. Legs without modifications, tibial terminal spurs paired. Tergite VII subtruncate at posterior margin. Morphological sternite VII broadly subtriangular, subtruncate medially at posterior margin. Aedeagus as in Fig. 45D–E ,

subcylindrical, rounded apically; endophallic armature of a series of paired, anteromediadpointed, rather thick spines.

Ecology. Unknown.

Distribution. Egypt.

Chorotype. SW­Asiatic (1.13 SWA), considered restricted to Sinai Peninsula.
