Hi. The name of the genre is Scytodes, maybe S. thoracica or S. univittata... 99% spiders species have venom, but this genre is not dangerous and also useful ally. Regards.
Roberto Ardovini -- It is definitely a member of the genus Scytodes. Without examining a mature specimen it is unclear what species, though I do not believe it is S. thoracica. There are many species that are invasive, but the two mentioned by Francisco Javier Sánchez-Camacho are both reported from Italy. This genus of spiders do not have venom glands associated with their fangs, so will not have a dangerous bite. On identification, does this spider only wander or does it make a web? I have found an invasive species on the outside of my house that has eliminated most of the other spiders and thus it does have a negative impact. Is your spider a wandering species or does it make webs?
