Bovallius. 



longest is almost half the length of all the distal segments of the flagellum 

 together. Antennae II are more than twice longer than antennae I; their 

 peduncle in young individuals is longer, in larger individuals shorter than 

 54 the flagellum; the flagellum is three- to four- segmented, the proximal 

 segment is long and styletlike; the two-three distal segments are short. 



The structure of the mouthparts is nearly identical in all the species of 

 the genus . The mandibles have a broad cutting edge that is narrower than the 

 body of the mandible, and a long, strong, three-segmented palp that is much 

 longer than the body of the mandible; the 1st segment of the palp is short.
