Prosternal process at apex with or without raised apical margin............................................................................. 3

3 Seta of metatrochanter absent. Metatarsomeres gracile ( Fig. 11 View FIGURE 11 A).............................................. 4

4 Metatarsomeres 1–2 with dorsolateral sulcus clearly impressed and with distinct lateral carina ......................... 5
- Metatarsomere 1–2 without dorsolateral sulcus or with only a shallow often interrupted, short sulci and no carinae or with a very low rounded raised lateral bead..................................................................... 8
5 Lateral margins of pronotum with slight or no sinuation. Hind angles variously angled, but usually obtusely angled. Relative size of pronotum various............................................................................... 6
- Pronotum rectilinear across base, lateral margins with obvious sinuation in basal forth and then straight to the hind angles. Hind angles about right angled. Pronotum relatively small and narrow................. Platycoelus interstitialis View in CoL ( Fig. 2 View FIGURE 2 B)
6 Proepisternum, mesepisternum, metepisternum and lateral edge of metasternum smooth or with a few scattered, small and very shallowly punctures.................................................................................... 7

7 Pronotal lateral margins slightly to notably sinuate before the base. Aedeagus with narrowly rounded apex ( Fig. 6 View FIGURE 6 B), ventral surface convex ( Fig. 6 View FIGURE 6 A).......................... Platycoelus irideomicans View in CoL (probably a complex of species, Fig. 2 View FIGURE 2 D)
- Pronotal lateral margins not or only very slightly sinuate before the base. Aedeagus with broadly rounded apex ( Fig. 7 View FIGURE 7 D), ven- tral surface flat ( Fig. 7 View FIGURE 7 C)......................................................... .. Platycoelus politus View in CoL sp. nov.
8 Proepisternum, mesepisternum, metepisternum and lateral edge of metasternum densely, shallowly punctate............. 9

9 Pronotum finely and sparsely punctate over entire surface including the basolateral depressions...................... 10
- Pronotum coarsely and densely punctate over disc, especially across the basal third and in the basolateral depressions...................................................................................... Platycoelus orion View in CoL sp. nov.
10 Elytral intervals with microsculpture not apparent, not visible at 50x magnification. Dorsally very shiny with prominent spec- tral iridescence. Elytral intervals very flat.................................... Platycoelus planipennis View in CoL ( Fig. 3 View FIGURE 3 B; 6I,J)
- Elytral intervals with microsculpture apparent, slightly transverse. Dorsally slightly dull or moderately shiny and with very slight spectral iridescence. Elytral intervals slightly convex.................... Platycoelus caledonicus View in CoL ( Fig. 1 View FIGURE 1 D; 5C,D)
11 Head at the level of the posterior supraorbital setae punctate................................................... 12
