description: Key to species of Megalotheca, based on males
1 Hind edge of pronotal lateral lobe distinctly oblique (Figs 11, 14, 15). Cercus distinctly elongate, not widened, and with almost acute apex (Figs 30, 33, 36, 38) .............................................................................................................................. 2
– Hind edge of pronotal lateral lobe more or less vertical (Figs 19, 22). Cercus weakly elongate or short, distinctly widened in distal, middle, or proximal parts, and with diverse apex (Figs 40, 44, 45, 47, 48, 51)............................................................. 6
2 Both pairs of wings shortened, distinctly not reaching abdominal apex. Cercus with large denticle behind middle part [Madagascar] ............................................ ................................................................................ C. (M.) xiphidioides (Karny)
– Wings diverse. Cercus with large denticle at proximal or middle parts (Figs 30, 33, 36,38) ................................................................................................................... 3
3 Both pairs of wings shortened, distinctly not reaching abdominal apex. Cercus with very long distal part behind large denticle (this part distinctly longer than rest of cercus; Figs 30, 38) .......................................................................................... 4
– Both pairs of wings long, extending behind abdominal apex. Cercus with not very long distal part behind large denticle (this part almost equal to rest of cercus in length or slightly shorter; Figs 33, 36); hind part of genital plate as in Fig. 34 ... 5
4 Pronotum shorter (ratio hind femur/pronotum about 3.5; Fig. 11). Cercus with large denticle rather thick and not S-shaped; cercal medial edge between this denticle and cercal apex with concave middle part (Fig. 30); hind part of genital plate as in Fig. 31 [Tanzania] .................................................... C. (M.) phasma Gor. et Llor.
– Pronotum longer (ratio hind femur/pronotum about 3; Fig. 14). Cercus with large denticle rather thin and slightly S-shaped; cercal medial edge between this denticle and cercal apex with convex middle part (Fig. 38) [Zimbabwe] ............................ .................................................................................... C. (M.) longiceps (Pering.)
5 Head distinctly longer (similar to that from Fig. 11) – interspace between eye and posteroventral corner of epicranium slightly longer than fore femur. Cercus with large denticle less curved and with distal part behind it slightly longer (Fig. 33) [Madagascar] ........................................................ C. (M.) marcelloi Gor. et Llor.
– Head distinctly shorter (Fig. 15) – interspace between eye and posteroventral corner of epicranium distinctly shorter than fore femur. Cercus with large denticle more curved and with distal part behind it slightly shorter (Fig. 36) [Namibia] ............. ......................................................................................... C. (M.) namibius sp. n.
6 Ventral edge of pronotal lateral lobe with shallow (but distinct) notch in hind half (Fig. 19). Cercus weakly elongate, distinctly widened in proximal part, and with almost acute apex (Figs 39, 40); genital plate with slightly widened apex and long styles (Fig. 41) [South Africa: KwaZulu-Natal] .................. C. (M.) zlobini sp. n.
– Ventral edge of pronotal lateral lobe without distinct notch (Fig. 22). Cercus short, distinctly widened in distal or middle parts, and with diverse apex (Figs 43–48, 50, 51); genital plate with somewhat narrower apex and reduced styles (Figs 49, 52) ... .............................................................................................................................. 7
7 Cercus with almost acute apex and large denticle almost angularly curved at base (Figs 43–45) [South Africa: Western Cape] ..... C. (M.) montana (Uv.), comb. n.
– Cercus with widely rounded apex and large denticle curved more or less roundly (Figs 46–48, 50, 51) ............................................................................................. 8
8 Cercus shorter and with large denticle shorter and less arched (Figs 50, 51); genital plate with shallow apical notch (Fig. 52) [South Africa: Western Cape] ............... ...................................................................... C. (M.) vaginalis (Karny), comb. n.
– Cercus longer and with large denticle longer and more arched (Figs 46–48); genital plate with rather deep apical notch (Fig. 49) [South Africa: Western Cape] .......... ...................................................................... C. (M.) parvula (Pering.), comb. n.
