Key to Species Groups of Campsicnemus  in French Polynesia

(based on males)

1. Fore coxa with a cluster of three to 4 black setae subapically on anterior surface (directed forward) that appear to be fused together to form a thorn-like projection ( Fig. 2View FIGURE 2); mid basitarsus shortened and with an apical spur of varying shapes or strong apical seta ( Figs. 3–6View FIGURES 3 – 6) ... (Marquesas). ...................................................................... gladiator  group

-. Fore coxa without a modified cluster of setae; mid basitarsus not as above................................................................ 3

2. Mid femur with conspicuous ventral swellings and concavities with associated patches of strong setae (e.g., Figs. 14–16View FIGURES 14 – 16) ................................................................................................................................................... englundi  group

-. Mid femur normal in shape and without setae in patches as above.............................................................................. 2

3. Fore tibia with conspicuous hook-like or pad-like sclerotized protuberance apically ( Figs. 23–27View FIGURES 23 – 27)...(Marquesas) ...... ..........................................................................................................................................................................aa group

-. Fore tibia without such a protuberance apically (not to be confused with an apical tibial comb, which is not a sclero- tized structure of the tibia) ............................................................................................................................................ 4

4. Mid basitarsus with conspicuously long, thick setae ( Figs. 17–20View FIGURES 17 – 20)... (Marquesas) ................................. hihiroa  group

-. Mid basitarsus without such long setae ... (Society Islands) ........................................................................................ 5

5. Wing with apical spot and/or band of infuscation on posterodistal portion; wing often falcate apically; mid femur without strong black setae of varying shapes on apical third of ventral surface l ...................................... obatus group

-. Wing without an apical spot or band of infuscation distally; mid femur with short, strong black setae of varying shapes on apical third of ventral surface. ................................................................................................... zigzag group
