3 Anterior process (ap) perpendicular to the main opisthomere body, with toothed apex ( Fig. 5d View FIGURES 5 a – g ).............. M. silvaticum View in CoL
- Anterior (ap) process parallel to the main opisthomere body, with normal blunt apex ( Figs 4d, 4f View FIGURES 4 a – l )........... M. projectum View in CoL
4 Posterior solenomere process (psp) large, massive, standing high above the anterior solenomere process (asp) ( Fig. 2d View FIGURES 2 a – f ). Dark grey animals with very wide reddish longitudinal band......................................... M. erythronotum View in CoL
- Posterior solenomere process (psp) subequal to the anterior solenomere process (asp) ( Fig. 3d View FIGURES 3 a – f ). Reddish-brown animals with two bright longitudinal dorsal bands............................................................ M. metsovoni View in CoL
5 Apical anterior hump (ah) well developed into a more or less blunt protuberance in front of the anterior solenomere process (asp)............................................................................................... 6
- Apical anterior hump (ah) not detectable................................................................ 11
6 Promere with a unique rod-like process below its apex ( Fig. 14c View FIGURES 14 a – g ). Dark grey animals with two bright dorsal longitudinal bands; uniformly dark forms also present........................................................ M. transsylvanicum View in CoL
- Promere with normal apex............................................................................. 7
7 Posterior process (pp) joining the main opisthomere body at a relatively wide angle of ca. 50˚ ( Fig. 17b View FIGURES 17 a – g ). Promere strongly tapering ( Fig. 17c View FIGURES 17 a – g )....................................................................... M. spathulatum View in CoL
- 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 View FIGURES 16 a – g ). Uniformly dark brown animals without longitudinal lines............................................................................................... M. rhodopinum View in CoL
- 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 View FIGURES 19 a – f ). Plain brownish animals............................................................................ M. tauricum View in CoL
- 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 View FIGURES 17 a – g ). Promere posteri- orly with a large lateral lobe (l on Figs 17a, 17c View FIGURES 17 a – g ). Brown animals with two bright longitudinal bands...... M. sjaelandicum View in CoL
- Posterior solenomere process (psp) normal, maybe only slightly ticker than the anterior solenomere process (asp) ( Fig. 17b View FIGURES 17 a – g ). Promere without a prominent lateral lobe. Dark grey animals with one bright dorsal longitudinal line...... M. unilineatum View in CoL

- 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 View FIGURES 14 a – g *). Dark grey animals with two yellowish dorsal longitudinal bands............................................ M. kievense View in CoL
- Posterior process (pp) much shorter than solenomere, apically smooth like the anterior solenomere process (asp) ( Fig. 13b View FIGURES 13 a – f ). Males uniformly dark grey with reddish legs; females with two bright longitudinal dorsal bands.......... M. rosenauense View in CoL
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 View FIGURES 9 a – g ) and a shelf-like protrusion from the distal part of its ante- rior surface ( Fig. 9c View FIGURES 9 a – g )......................................................................... M. dentatum View in CoL
