Ariadna dysderina (RM)|
or a closely related species
female: 12 mm|
male: 10 mm
This species likes to build a retreat under rocks or logs, this having a distinctive entrance consisting of a dense collar of silk. Radiating
threads support it and warn the spider of nearby insects. The burrow also has a lining of threads that run along its length
The toxicity of this spider's venom is unknown but it may cause mild illness in humans so this species should be handled with caution
This species mostly is uniformly dark coloured and has three pairs of legs pointing forward and the fourth pair pointing backwards. Only six eyes are present
and there is a slit-like spiracle entrance just behind each book lung.
Spider(s) with a very similar appearance: Many other spider species with 'unspecialised' body shapes.
