I couldn't see one defined here:

http://www.ruby-doc.org/core/classes/Module.html#M000474
mod.name --> string
Returns the name of the module mod. Returns nil for anonymous modules.

http://www.ruby-doc.org/core/classes/Module.src/M000474.html
/*
 *  call-seq:
 *     mod.name    -> string
 *
 *  Returns the name of the module <i>mod</i>.  Returns nil for
anonymous modules.
 */
VALUE
rb_mod_name(VALUE mod)
{
    VALUE path = classname(mod);

    if (!NIL_P(path)) return rb_str_dup(path);
    return path;
}

Perhaps something like:

class Module
  def path_last_name()
    if (i = (r = name).rindex(':')) then r[0..i] = '' end
    r
  end
end
