( 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 . Previous records from the Caucasus. Western Caucasus (unspecified type locality) ( Lohmander 1936 ). General distribution. WCIS? Remark. This species seems to be a narrow local endemic of the northwestern foothills of the Caucasus Major, showing preferences for limestone terrain.
