Key to species of Fulgenta (males)

1. Basiphallus cuboidal in shape ( Figs. 17 & 18 )...............................................................2

- Basiphallus not cuboidal in shape ( Figs. 9 , 13 , 22 )...........................................................4

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

- Distiphallus without such medial processes ( Figs. 26 & 30 ).................................................. 11

8. Medial processes of distiphallus in the form of rounded lobes ( Figs. 22 & 34 )......................................9

- Medial processes of distiphallus spine-like ( Figs. 9 & 47 )..................................................... 10

9. Medial processes as long as wide ( Fig. 22 ), basiphallus rather narrow and sinuous............................ F. excisa

- Medial processes as wider than long, basiphallus broader and straighter ( Fig. 34 )......................... F. longicerca

10. Distiphallus with two almost 90° bends ( Fig. 47 ), cerci relatively broad, at apex slightly angled towards centre, extending only slightly beyond epandrium ( Fig. 44 ). Apex of wing clear.............................................. F. pretoria

- Distiphallus sinuous and less angular with longer internal spines ( Fig. 9 ), cerci narrow with medial apical processes, extending well beyond epandrium ( Fig. 6 ). Apex of wing darkened. ( Fig. 1)....................................... F. apicalis

11. Apical section of phallus with an almost 90° angle ( Fig. 30 ).............................................. F. geneti

- Apical section of phallus without a 90° angle 80°, 20°........................................................12

12. Phallus C-shaped, with small lateral projections basally and apically ( Fig. 26 ). Cerci broad, broadening steadily from base, api- cally with a small rounded process medially ( Fig. 23 )................................................ F. freidbergi

- Phallus J–shaped, basiphallus with a few small setulae, distiphallus long and sinuous with a small outer process ( Fig. 60 ). Cerci broadening from base for 60% of their length then narrowing to a bluntly pointed apex ( Fig. 57 )........ F. setiphallus
