A. ericeti is a continental European species not found in the UK, and British specimens may be more accurately considered as A. longicollis (e.g. Denton 2009). A. ericeti is used in Duff's 2008 checklist (Duff 2008) but updated to A. longicollis in the 2012 edition (Duff 2012). The junior synonym A. britteni may also be found in use e.g. in Kevan (1962) which keys out British species using features of the dissected-out genitalia.
