Most members of this family can be identified as such by the presence of prominent, tube-shaped spinnerets.

However, note that there are other families with spinnerets that can look similar, such as the Clubionidae:

For Gnaphosidae vs. Clubionidae, look for an eye arrangement that is much more tightly clustered. Example gnaphosid eye arrangement:
Exact distribution within these countries will be added when time permits.
