Aulacorthum capilanoense Robinson 1969 = Amphorophora forbesi Richards 1959
The original description of Aulacorthum capilanoense, and specimens from Rubus spectabilis from various places and dates in British Columbia and Oregon, agree with a paratype of Amphorophora forbesi, decribed from R. spectabilis from Lulu Is, British Columbia. This species has an unusual combination of characters (rather large size, spiculose ventral side to head, steepĀsided antennal tubercles, no rhinaria on antennal segment III, slightly swollen siphunculi and a rather hairy cauda), so its generic position is not certain.
