Key to the South Korean genera of Laphriinae treated in this paper

1. Proboscis short ( Fig. 25 ), triangular in cross­section; vein closing discal cell aligned with vein closing fourth posterior cell ( Fig. 23 ); metallic purple/blue flies ............................................................ Orthogonis

­ Proboscis much longer, laterally flattened ( Figs 24, 26–28 ); vein closing discal cell not aligned with vein closing fourth posterior cell......................................................................................................................... 2

2. Parafacial hair in dense gold/yellow/silver/black mats, clearly differentiated from surrounding hairs and bristles; elongated, slender setose flies, not resembling bumble bees; gonocoxite clearly separated into 2 halves by a depression or long setae ............................................................................................ Choerades

­ Parafacial hair not in dense mats, not different from surrounding hairs and bristles; short, squat, heavily setose flies resembling bumble bees; gonocoxite not separated into 2 halves ................................. Laphria
