The following (possibly more) can't be minitored easily due to their abnormal channel name.
- pa.us.wikimedia.org (?) 
Note that #commons.wikimedia and #meta.wikimedia and Wikisource are fine and represent the domainname exactly.
Bots using irc.wikimedia.org to monitor vandalism (ie. the [[m:Countervandalism Network]]) are unable to monitor these (unless hacking the bot and hardcoding the paths).
species.wikipedia is a bit of an exception as species.wikipedia.org redirects to species.wikimedia.org so that one still works when monitored through the bot as 'species.wikipedia' it will be able to connect to species.wikipedia.org/w/api.php (as it redirects)
The others are however hard to monitor (eg. not monitored) as the channel neither matches the hostname nor the interwiki prefix. As a result the small-wiki monitoring team is unable to properly monitor these wikis.
Please move #mediawiki.wikipedia to MediaWiki-General as soon as possible (and leave the old channel as redirect for backwards compatibility for those that have hardoded the paths)
I was unable to find where this chapter wiki is monitored, nor have I found a way to link to it with an interwiki link on-wiki (There is no pa-us or pa.us wiki)
