Holcaspis oedicnema is a ground beetle of the family Caraboidea. This family of which there is some variation in their body shape and colouring, most are shiny black or metallic and have ridged wing covers (elytra). The elytra are fused in some species, particularly large Carabinae, rendering the beetles unable to fly.  All carabids except the quite primitive flanged bombardier beetles (Paussinae) have a groove on their foreleg tibiae bearing a comb of hairs. This is used for cleaning their antennae.
