5. In the phallic organ, sclerite of the ventral lobe roughly oval in dorsal view, with the right protuberance directed anteriorly and the left one directed caudally ( Fig. 14 View FIGURE 14 , in green)............................................. Paraphasma laterale View in CoL

6. Tegmina shoulder pads spiniform or dull; in the phallic organ, sclerite of the ventral lobe bearing three protuberances (i.e., apical, left basal and right basal protuberances), all of them undivided ( Figs 22 View FIGURE 22 , 28 View FIGURE 28 : ap, lp, rp)........................ 7
- Tegmina shoulder pads spiniform; in the phallic organ, sclerite of the ventral lobe bearing one or two protuberances (right basal protuberance absent) ( Fig. 4 View FIGURE 4 : ap, lp; Fig. 9 View FIGURE 9 : lp), with the left basal one partially or completely divided in two............ 8
7. Tegmina shoulder pads spiniform or dull; in the phallic organ, sclerite of the ventral lobe roughly triangular in dorsal view, with somewhat acuminate posterior margin ( Fig. 28B View FIGURE 28 ), and with the three protuberances blunt and conspicuous ( Fig. 28 View FIGURE 28 : ap, lp, rp)....................................................................................
