Dark grey animals with two bright dorsal longitudinal bands; uniformly dark forms also present........................................................ M. transsylvanicum - Promere with normal apex............................................................................. 7 7 Posterior process ( pp ) joining the main opisthomere body at a relatively wide angle of ca. 50˚ ( Fig. 17b ). Promere strongly tapering ( Fig. 17c )....................................................................... M. spathulatum - Posterior process ( pp ) joining the main opisthomere body at a more acute angle of not more than 20˚–30˚. Promere more grad- ually narrowing..................................................................................... 8 8 Posterior process ( pp ) shorter than solenomere ( Fig. 16d ). Uniformly dark brown animals without longitudinal lines............................................................................................... M. rhodopinum - Posterior process ( pp ) subequal to solenomere............................................................. 9 9 Anterior solenomere process ( asp ) more than two times longer than the posterior solenomere process ( psp ) ( Fig. 19d ). Plain brownish animals............................................................................ M. tauricum - Anterior solenomere process ( asp ) just slightly exceeding the posterior solenomere process ( psp ).................... 10 10 Posterior solenomere process ( psp ) enlarged, thicker than the anterior solenomere process ( asp ) ( Fig. 17b ). Promere posteri- orly with a large lateral lobe ( l on Figs 17a, 17c ). Brown animals with two bright longitudinal bands...... M. sjaelandicum - Posterior solenomere process ( psp ) normal, maybe only slightly ticker than the anterior solenomere process ( asp ) ( Fig. 17b ). Promere without a prominent lateral lobe. Dark grey animals with one bright dorsal longitudinal line...... M. unilineatum 11 Anterior solenomere process ( asp ) strongly elongated, surpassing by far the posterior solenomere process ( psp )......... 12 - Anterior solenomere process ( asp ) shorter or subequal to the posterior solenomere process ( psp )..................... 13 12 Posterior process ( pp ) subequal to solenomere, apically serrated, as the anterior solenomere process ( asp ) ( Fig. 14d *). Dark grey animals with two yellowish dorsal longitudinal bands............................................ M. kievense - Posterior process ( pp ) much shorter than solenomere, apically smooth like the anterior solenomere process ( asp ) ( Fig. 13b ). Males uniformly dark grey with reddish legs; females with two bright longitudinal dorsal bands.......... M. rosenauense 13 Posterior solenomere process ( psp ) much longer and wider than the anterior solenomere process ( asp )................ 14 - Posterior solenomere process ( psp ) subequal to the anterior solenomere process ( asp ).............................. 17 14 Promere apically with a large toothed or serrated lobe ( sl on Fig. 9a ) and a shelf-like protrusion from the distal part of its ante- rior surface ( Fig. 9c )......................................................................... M. dentatum - Promere without special characters..................................................................... 15 15 Posterior solenomere process ( psp ) swan-neck shaped; posterior process ( pp ) higher than solenomere ( Fig. 8d ).................................................................................................... M. cygniforme - Posterior solenomere process ( psp ) differently shaped; posterior process ( pp ) subequal to solenomere................. 16 16 Posterior solenomere process ( psp ) wavy ( Fig. 11d ).

M. glossulifer 17 Posterior process ( pp ) surpassing solenomere............................................................. 18 - Posterior process ( pp ) shorter or subequal to solenomere..................................................... 19 18 Posterior process ( pp ) wide and rounded, fully concealing solenomere from posterior view ( Fig. 12a ); posterior solenomere process ( psp ) smooth ( Fig. 12d ). Dark grey animals with yellow to reddish dorsal side, usually with a thin blackish mid-dorsal line..................................................................................... M. bosniense - Posterior process ( pp ) slender, strongly tapering; posterior solenomere process ( psp ) wavy ( Fig. 7b ). Dark brown or grey animals with thin mid-dorsal black line........................................................... M. carniolense 19 Posterior process ( pp ) wide and rounded; anterior and posterior solenomere processes ( asp and psp ) slender, finger-like ( Fig. 15d ). Very large dark grey animals with narrow, yellow to reddish longitudinal dorsal band..................
