FOREWORD

The f irst edit ion ot rhe Provisional Atlas oftheAnts (Formicidae) oftheBrit ish lsles wascompiled with data available up to May 1977. We are grateful to l\rr Barrett for providing andedit ing the addit ional data included in this, the second edit ion ot the Provisional Atlas.

The maps included in this Atlas were prepared under contract to the Nature ConservancvCouncil as part of its programme of research into nature conservation,

PREFACE TO THE SECOND ED IT ION

In the preparation of the second edition, the opportunity has been taken to make certaincorrections, to update the nomenclature used and to include records contributed to the recordingscheme up to Jufy 1979. Since the first edition, a new species, Mymica hirsuta Elmes, has been

described, bringing the total number ol species o{ ants in the British lsles to forty-seven.

Future recording of ants in the Brit ish lsles wil l be organised through the Bees, Wasps and

Ants Recordlng Scheme co-ordinated by:

INTRODUCTION

The foliowing maps illustfate the presently known occurrence of 47 species of ants, including 5

onlv known in the Brit ish lsles from the Channel lsles, in the 10 ki lometre squares of the Ordnance

Suruey and lrish National Grids, The maps are based on published records, museum records and,primarily, on field records contributed both by specialist collectors and by participants in the AntRecording Scheme, This scheme, like many similar schemes concerned with the distribution o{ the

major insect groups, is organised in cohjunction with the Biological Records Centre.

Only the species known to be indigenous to the British lsles are represented on the maps. Intrc-duced species, incfuding the doubtfully endemic Hypoponerc punctatissima (Roger), are not included.Afthough taslus rabaudi lEondroill is currently treated as a synonym ol L. umbratus {Nylander), thedistribution rnap ot this form is rctained since the Oueen caste is readily separable. Collingwood (1979,Fauna Entomologica Scandinavica, 8) considers British material recorded as L. rabaudi 10 be referableto L. meridionalis IBondroit].

It should be pointed out that the absence ol records for any given square, particularly in the caseof the more abundant and widespread species, may be due more to the absence of records than to theabsence q{ ants. For this reason, a map of all the records obtained is provided for comparison with thespecies distribution maps so that indication is given of the status of the records and of areas wherefurther recording is required.

lvly grateful thanks are due to all those who have generously contributed records to the AntRecording Scheme to date.
