description: 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. 5d).............. M. silvaticum
- Anterior (ap) process parallel to the main opisthomere body, with normal blunt apex (Figs 4d, 4f)........... M. projectum
4 Posterior solenomere process (psp) large, massive, standing high above the anterior solenomere process (asp) (Fig. 2d). Dark grey animals with very wide reddish longitudinal band......................................... M. erythronotum
- Posterior solenomere process (psp) subequal to the anterior solenomere process (asp) (Fig. 3d). 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. 14c). 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). Uniformly dark brown animals................... M. montivagum
- Posterior solenomere process (psp) smooth (Fig. 10d)............................................. 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.................. M. hercules
- Posterior process (pp) narrow, apically pointed; anterior and posterior solenomere processes (asp and psp) rather short, weakly protruding (Fig. 6d)........................................................................ M. austriacum
