On a trip in february 2006 on La Gomera I discovered a pocket guide: Natural history of the Canary Islands written by David Bramwell and Juan Manuel López and to my surprise some of the pages were dedicated to spiders.
The arachnids on the Canary islands are well studied (by Wunderlich) and there are over 150 different species identified.
The most astounding presence is the lady bird spider. Because I could not find her I placed look alikes.
