Potential problems with identification

Diabrotica viridicollis Jacoby is very similar to D. v1n, D. v2n and D. v3n. They can be separated by the following features: head is yellow with chestnut vertex in D. viridicollis, green with brownish olive vertex in D. v1n and black in D. v2n and D. v3n; pronotum is nonfoveate in D. viridicollis, but foveate in D. v1n, D. v2n and D. v3n; pronotum not shagreened in D. viridicollis, but shagreened in D. v3n; black bands are strongly marked in D. viridicollis, but reduced to a substantial degree in D. v1n; body shape is more convex and wider in D. viridicollis than in D. v1n and D. v3n; D. viridicollis is larger than D. v3n, but smaller than D. v2n.
