The Natural World in Close Up

Spiders of Cornwall
The checklist includes links to maps of the distribution by tetrads (2 km by 2 km Ordnance Survey grid squares) of all species of spider known from Cornwall and the Isles of Scilly (Watsonian Vice Counties 1 and 2). The maps comprise records held by the Spider Recording Scheme (SRS) of the British Arachnological Society (BAS), the Environmental Records Centre for Cornwall and the Isles of Scilly (ERCCIS), and new localities added since the publication of Harvey, Nellist & Telfer (2002) Provisional Atlas of British Spiders (Arachnida, Araneae), Biological Records Centre, Huntingdon [Click here to download an order form for this Atlas].
     Map 1 shows the tetrads from which at least one species of spider has been recorded. Overall coverage is quite good. However, expressing the data in this way disguises the fact that the density of recording is very low (Map 2), except in a handful of well-worked localities such as Kynance Cove on the Lizard Peninsula. The region is very under-recorded and there is considerable potential for discovering species new to Cornwall, or even new to Britain.

Approximately 350 species of spider have been recorded from Cornwall and the Isles of Scilly (Watsonian Vice Counties 1 and 2). The data for each species includes a Distribution Map, text giving an overview of its rarity and distribution in Britain, and specific information on localities and dates of the most recent collections from Cornwall. The green symbol [P] against a species name indicates that there are one or more photographs included with the description.

• The number code refers to the National Spider Recording Scheme identification number given in Section 2.3 of the Members' Handbook of the British Arachnological Society [www.britishspiders.org.uk]
  
• The six digit letter code is a unique abbreviation usually comprising the first three letters of the genus name followed by the first three letters of the species name. Where this is ambiguous, slight changes to this convention have been made (e.g. the code for species number 466 Dictyna arundinacea is DICaru, whereas that for species number 104 Dicymbium nigrum is DIYnig)
  
• Species that have definitely been recorded from Cornwall and/or the Isles of Scilly are shown in BOLD text. A few species are shown in unemphasised text because a) they appear on early checklists for the County but their presence requires confirmation as there are no modern records, or b) the only records are held by ERCCIS and have not been validated by the Spider Recording Scheme
  
• Records held by the Environmental Records Centre for Cornwall and the Isles of Scilly (ERCCIS) are shown as Blue dots (most of these will be valid records but strictly speaking, they should be considered as 'unconfirmed' as they have not yet been validated by the Spider Recording Scheme). Records originally published in the Provisional Atlas of British Spiders (and validated pre-2002 records that have come to light since the publication of the Atlas) are shown as Green dots. New records verified since 2002 are shown as Red dots
  
• Where records from a specific tetrad overlap, Red dots take precedence over Green dots which take precedence over Blue dots
  
• A few unconfirmed records are shown as Yellow dots. These are included merely to indicate the possible presence of a species in a tetrad but are not definite records
  
• Dots will be added to the existing maps as new localities are discovered. The date on which distribution information was last revised is shown in the title adjacent to the species name on each map. Important new records are listed after the Checklist
  
• The maps were produced using DMAP [www.dmap.co.uk].
