Key to males of subgenus Megaphyllum sensu  stricto on the basis of gonopod characters and body colour patterns

1 Anterior process (ap) well discernible.................................................................... 2

- Anterior process (ap) reduced to a low ridge or fully absent................................................... 5

2 Posterior process (pp) shorter than solenomere............................................................. 3

- Posterior process (pp) longer or subequal to solenomere...................................................... 4

3 Anterior process (ap) perpendicular to the main opisthomere body, with toothed apex ( Fig. 5 dView FIGURES 5 a – g).............. M. silvaticum 

- Anterior (ap) process parallel to the main opisthomere body, with normal blunt apex ( Figs 4 d, 4 fView FIGURES 4 a – l)........... M. projectum 

4 Posterior solenomere process (psp) large, massive, standing high above the anterior solenomere process (asp) ( Fig. 2 dView FIGURES 2 a – f). Dark grey animals with very wide reddish longitudinal band......................................... M. erythronotum 

- Posterior solenomere process (psp) subequal to the anterior solenomere process (asp) ( Fig. 3 dView FIGURES 3 a – f). Reddish-brown animals with two bright longitudinal dorsal bands............................................................ M. metsovoni 

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. 14 cView FIGURES 14 a – g). 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. 17 bView FIGURES 17 a – g). Promere strongly tapering ( Fig. 17 cView FIGURES 17 a – g)....................................................................... 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. 16 dView FIGURES 16 a – g). 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. 19 dView FIGURES 19 a – f). 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. 17 bView FIGURES 17 a – g). Promere posteri- orly with a large lateral lobe (l on Figs 17 a, 17 cView FIGURES 17 a – g). 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. 17 bView FIGURES 17 a – g). 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. 14 dView FIGURES 14 a – g *). 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. 13 bView FIGURES 13 a – f). 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. 9 aView FIGURES 9 a – g) and a shelf-like protrusion from the distal part of its ante- rior surface ( Fig. 9 cView FIGURES 9 a – g)......................................................................... M. dentatum 

- Promere without special characters..................................................................... 15

15 Posterior solenomere process (psp) swan-neck shaped; posterior process (pp) higher than solenomere ( Fig. 8 dView FIGURES 8 a – f).................................................................................................... M. cygniforme 

- Posterior solenomere process (psp) differently shaped; posterior process (pp) subequal to solenomere................. 16

16 Posterior solenomere process (psp) wavy ( Fig. 11 dView FIGURES 11 a – g). Uniformly dark brown animals................... M. montivagum 

- Posterior solenomere process (psp) smooth ( Fig. 10 dView FIGURES 10 a – g)............................................. 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. 12 aView FIGURES 12 a – g); posterior solenomere process (psp) smooth ( Fig. 12 dView FIGURES 12 a – g). Dark grey animals with yellow to reddish dorsal side, usually with a thin blackish mid-dorsal line..................................................................................... M. bosniense
