Yorkshire Ichneumons: Part 1

摘要

The study of Yorkshire's ichneumons in recent years has resulted in many additions to the county list and many more for each vice-county. These are included in the list maintained on the YNU website but most of the additions have not been formally reported in The Naturalist. Several have been published in the pages of the Sorby Record or other publications. The fact that such references are quoted here as a record of occurrence in a particular vice-county does not necessarily mean that they refer tothe earliest record, just the earliest publication. The specimens on which many of the earlier references are based have not been found and checked, so these references are included as unconfirmed in order to acknowledge the contributions of previous workers. If there is a later confirmed specimen then that is reported here as the first accepted vice-county record. Some of the unconfirmed records are due to taxonomic changes, some quite recently. The specimens on which these published reports are basedmay still exist and they may be located and verified in the future, as some have already been traced and confirmed. In some cases it will be apparent that the earliest record is not shown as being 'new to Yorkshire'. There is a difference between the first and the earliest Yorkshire records and it is quite common for a species to be published as 'new to Yorkshireew to VC61, etc' only for one or more earlier specimens to be discovered subsequently. I have identified or checked all the new records reported here unless otherwise specified.
