Appearance
''Umbonia spinosa'' can be distinguished from other members of its genus by the appearance of its dorsal horn. Its dorsal horn pronotum is located between or just behind its humerais and they possess a short metopidium. Dorsal horn pronotum itself is straight and the base of the plate is yellow, testaceous or pale green, with red or yellow vittae each side, though sometimes ''U. spinosa'' can be characterized by black vittae. The dorsal horn gradually tapers to a point from base to summit, similar to a thorn in appearance.
Distribution
''Umbonia spinosa'' is distributed within regions of South America, including Venezuela, Dutch Guiana, British Guiana, and Ecuador.References:
