Key to known immature stages of the Palaearctic species of the genus Anthonomus View in CoL

The larva and pupa of A. rectirostris and the pupae of A. pedicularius and A. pyri have not been studied by me and are included according to the works of Burke (1968) and Ahmad & Burke (1972). It should be borne in mind that according to the works of Marvaldi (1997; 1999), des 3 in the sense of Ahmad and Burke should be called des 4, while des 4, respectively, des 3, pds 5 on meso- and metathorax are alar setae (as). I did not include the larva of A. bisignifer described by Lee & Morimoto (1996) in the key (see discussion).
