This insect approaches in its antennae and setose body to the genus 

 Nosodendron, but the oral structure is more nearly allied to that of 

 Byrrhus. The 3 basal joints of the tarsi are strongly ciliated, while 

 the 4th is naked, and seems almost incorporated with the 5th joint. 

 The tubercles on the thorax and elytra are formed of short rigid hairs.
