2. In posterior view, apex of each cercus divided into two distinct lobes, lateral much longer than medial (Fig. 14), basiphallus with a relatively simple, apically serrated medial process: distiphallus straight, arising basally, (Figs. 17 & 18).. F. complexa
- In posterior view apex of each cercus not divided into distinct lobes, basiphallus with spiculate projections: distiphallus sinu- ous, arising medially (Figs. 43 & 51)..................................................................... 3
3. Cerci with apices almost straight apart from a small medial process (Fig. 39). Basiphallus spiculate on anterior surface, without anteriorly directed processes (Fig. 43)............................................................. F. plumosa
- Cerci with apex curved towards a large, broad medial process (Fig. 48). Basiphallus not spiculate on anterior surface, with two anteriorly directed lateral and basal processes (Figs. 51 & 52).......................................... F. saegeri
4. Phallus a simple U-shape or J-shape without any sinuosity or internal processes (Figs. 38 & 56)...................... 5
- Phallus sinuous or angled or with medial or lateral processes................................................... 6
5. Phallus with a short, narrow apical section (Fig. 56), cerci broad, at apex each with a small medial process (Fig. 53)................................................................................................. F. sangmelima
- Phallus a simple J-shape (Fig. 38)............................................................. F. longiphallus
6. Phallus vase-shaped with a pair of small basal processes (Fig. 13), cerci broad, square ended, each with a bluntly pointed outer lobe at base. (Fig. 10).......................................................................... F. bilobata
- Phallus not vase-shaped, cerci not as above.................................................................7
7. Distiphallus with a pair of medial processes, these either rounded lobes or spine-like (Figs. 9 & 22)................... 8
