Diagnosis.

Differs from its only congener known from the Caucasus, M. (s. str.) Megaphyllum hercules, mainly by the colour pattern: body with a light yellow to ochre dorsum divided by a black axial line, vs. body uniformly dark with an orange to dark red mid-dorsal line in M. hercules; and by the promere significantly tapering all the way to a narrowly rounded apex, vs. the same having mostly parallel side margins, ending with a flat apex in M. hercules .
