Comments. This species is a member of the subgenus
Trichapion. Among Canadian species, it is most similar to A. porcatum
and somewhat less similar to A. reconditum. Ailits of A. centrale ate
distinguished from those of A. porcatum by the flat to very slightly
convex elytral interstriae that are about twice as wide as the striae. The
characters given in the key distinguish adults of A. reconditum from
those ofA. centrale. Nothing is known of the biolory or life history, other
