Description of the problem
The {exp:member:memberlist} tags can also make use of the group_id='' parameter, but it is not in the documentation.
{exp:member:memberlist
orderby="screen_name"
group_id="5"
sort="asc"
}

Additional context
I know this parameter is not ideal if you plan on using the member search functions along with it, but there are many cases where one would want to specify ONLY a specific group id to be represented in a list.
