Identification
In most species the male head is modified, but a few have the tips of the elytra modified into what look like flaps from an envelope. Still others lack any modification of the head or elytra. In the male front legs, the 1st tarsomere is modified into a broad lobe with spicules at the end, and the cluster of short spicules at the apex of tibiae. Fore over a century the species with modified elytra have been treated incorrectly as Anthocomus.
Females are difficult to differentiate from Attalus. In Nodopus, erect setae are absent from the elytra or restricted to a few scattered erect setae near the base of the elytra close to the pronotum. In Attalus females (at least the Eastern U.S. species), the species have erect black setae on the elytra. (A. Mayor, pers.comm. to B Barnd)
