Key to species of Bohumiljania

1. Sides of anterior half of pronotum swollen ( Figs. 1–2); pronotum and elytra chestnut brown; elytra glabrous and impunctate (pronotum with two elongate grooves on either side of basal half and hind angles not projecting; length [probably female] 14mm)............................................................................ B. caledonica (Jolivet)

- Sides of pronotum parallel or convex, but without anterolateral swelling ( Figs 5–12); without combination of brown upper surface and impunctate glabrous elytra....................................................................... 2

2(1) At least apical 1/6 of elytra conspicuously setose ( Figs 5, 12, 71) (elytral disc brown to olive-brown; pronotum densely setose, with two elongate grooves at sides of disc).................................................................. 3

- Elytra glabrous, or at most scattered minute setae present in apical 1/6 (elytral disc green to olive-green)................ 4

3(2) Elytra entirely olive-brown and setose ( Fig. 12); pronotal punctures in clusters; temples abruptly truncated posteriorly; femora dark brown with bronze reflection (length female 17mm)......................................... B. yuaga sp. nov.

- Elytra yellow laterally and at base, only setose in apical 1/6 ( Figs. 5, 71); pronotal punctures evenly spread; temples evenly contracted, not abruptly truncated; basal and apical quarters of femora yellowish (length male 9–10mm)...................................................................................................... B. aoupinie sp. nov.

4(2) Head and pronotum green ( Figs 7, 10); pronotum glabrous or at most sparsely setose ( Fig. 69) (pronotal anterior angles strongly laterally projecting in contrast to at most feebly projecting posterior angles; length males probably 12–17mm, females 17–23mm) .......................................................................................... 5

- Head and pronotum brown, yellowish-brown or orange ( Figs 6, 8, 9, 11, 12); pronotum densely pubescent at least at sides of disc ( Fig. 70) (length males probably 8–10mm, females 11–15mm).............................................. 6

5(4) Smaller, length males 14–15.5mm, females 17–20mm; dorsal surface of elytra not yellow at suture ( Fig. 7); prosternal process usually with concave sides ( Figs 49, 57–60); male sternite VII with feebly concave apex (figs 89–91); penis thinner, apex rounded in dorsal view ( Figs 102–104); spermatheca falcate with large basal swelling ( Figs 138–140)..... B. lafoa sp. nov.

- Larger, length males 16.5–17mm, females 21–23mm; elytra with narrow dorsal yellow stripe at suture ( Fig. 10); prosternal process with almost straight sides ( Figs 64–66); male sternite VII with distinctly concave apex ( Figs 93–95); penis thicker, apex concave in dorsal view ( Figs 106–108); spermatheca irregularly shaped with small median swelling ( Figs 143–144)................................................................................... B. xanthogramma sp. nov.

6(4) Prosternal process densely setose ( Figs 48, 51); pronotal hind angles 90° or less ( Figs 40, 43) (legs pale, elytra green with sides vaguely orange or yellow)............................................................................... 7

- Prosternal process almost glabrous, setose at side margins ( Figs 50, 53); pronotal hind angles more than 90° ( Figs 42, 45)... ................................................................................................... 8

7(6) Middle of pronotal disc punctate and pubescent ( Fig. 9); elytra strongly and closely punctured, apical 1/6 wrinkled; ventrites I–II with lateral keels; tarsi less elongate, length first metatarsomere 2x width ( Fig. 81) (length female 12mm)................................................................................................... B. tango sp. nov.

- Middle of pronotal disc impunctate and glabrous ( Fig. 6); elytra finely and sparsely punctured, not apically wrinkled; only ventrite I laterally keeled; tarsi more elongate, length first metatarsomere 2.8x width ( Fig. 76) (length female 14mm)................................................................................ B. humboldti Jolivet, Verma and Mille

8(6) Elytra strongly and closely punctured ( Fig. 8); femora and tibiae yellowish-brown, darkened at joint; lateral pronotal margins well-defined, without adjacent grooves or pits, weakly sinuate at hind angle ( Fig. 42); ventrites I–III laterally keeled ( Fig. 87); elytra green with sides vaguely orange or yellow (length male 8mm, female 11.5–12mm)............
