Linyphiid Key

A Revised and Updated Key to Linyphiids

Compiled by Lawrence Bee, March 2010


The following key is based upon the Key produced by Michael Roberts in The Spiders of Great Britain and Ireland, Volume 2 (1987) with the addition of species new to the UK since the publication of Robert's key.

With thanks to Peter Merrett, Ian Dawson and David Nellist for help with proofreading and to Mike Roberts for permission to adapt and upgrade his original key A Key to the Genera and Species of the British Linyphiidae
