IdentificationThis is 1 of 2 species of Chrysobothris with white hairs covering the elytra. These hairs are often short, inconspicuous or worn, leading a person to key the beetle out through the other half of Couplet 1 in the above key. The head and pronotum are also covered with white hairs. The sides of the pronotum are straight; and the base is wider than the width of the head. Each elytron has 3 or 4 costae with the first more strongly elevated towards the posterior. Three foveae are present, each densely punctured, and usually reddish in colour are located between the first and second costae, at the end of the third costae and one interrupting the middle of the second costa. The tooth on the profemur is serrate distally.
