Naming
The genus "Cheiracanthium" was transferred from the Clubionidae to the Miturgidae, and then to the Eutichuridae.Distribution
In Germany, where it is the only "seriously" venomous spider, it is a rare species, only known to occur in notable numbers in the Kaiserstuhl region, the hottest part of the country. Due to changing weather patterns, leading to increased aridity and less precipitation in some areas, this species spreads to more northern parts of Europe, e.g. Brandenburg, Germany, where the present trend is towards a climate more similar to the Central Asian steppes where "C. punctorium" is most numerous.References:
