– Ventral side metallic green.............................................................................. 4

2 Dorsal side of head the same colour as ventral side of entire body................................................ 3

– Dorsal side of head green or blue-violet; pronotum and elytra mostly blue to violet-black, rarely brown-bronze or green. Intercostae always well developed. Parameres very broadly regularly navicular, widest at mid-length, narrowly open at apical fifth; apex of penis broadly triangular. Taiwan. Figs 18–24 , 65, 66............. C . (C.) eximia berliozi Descarpentries, 1948

3 Lateral sides of ventrites II–IV densely macropunctate in entire width, 1 st costa mostly parallel with suture, sometimes only moderately bent in apical quarter; intercostae can be well developed or slightly indicated in some (rarely in all) intercostal intervals; mostly green, can be red-bronze or brown, antennae and tarsi never yellow. Generally more slender, length/width ratio: ♂♂ (n=6) 2.89–2.95(3.15) (average 2.95); ♀♀ (n = 75) 2.69–2.98(3.05) (average 2.85). Parameres broadly regularly navicular, widest at mid-length, narrowly open at apical third; apex of penis narrowly triangular. Philippines: Luzon Is. and Babuyan Isls.

– Lateral sides of ventrites II–IV densely macropunctate at basal half and sparsely macropunctate at apical half; 1 st costa bent in apical quarter and running obliquely to suture; intercostae absent; always brown, antennae and tarsi pale brown or yellow. Generally more broad length/width ratio: ♂♂ (n=14) 2.65–2.94 (average 2.78); ♀♀ (n = 46) 2.62–2.91(3.13) (average 2.75). Parameres broadly regularly navicular, widest at mid-length, narrowly open at apical half; apex of penis broadly triangular.

4 1 st costa mostly parallel with suture; elytra green, macropunctation at intercostal intervals regular. Generally more slender, length/width ratio: ♂♂ (n=25) 2.80–3.15 (average 2.95); ♀♀ (n = 34) 2.50–3.06 (average 2.83). Parameres broadly irregularly navicular, widest at mid-length strongly narrowed at apical half, narrowly open at apical third; apex of penis broadly triangular.
