The lateral edges of the abdomen, or connexivum, are marked with black and white. The white markings are triangular in shape. The upper part of the body has darker punctuation. The ventral surface is very sparsely punctuated and there is no ventral spine. There are five larval stages before the adult stage. The larvae have spines in front of their eyes, on the sides of their thorax, and on their femurs.
