Aryanmen 「亜両面」 is a variation on the ryanmen waiting pattern, where the two tiles completing the sequence are next to a pair of one of the waiting tiles. As a result, the hand also has a pair wait on that tile. It is generally a weaker wait, however, as the pair uses up two of the eight possible waiting tiles, leaving only six possible tiles to win off of.
Tile pattern
Waiting for: 
In this example, the underlying ryanmen wait is based on the 56m, but additionally, 567m can be viewed as a complete sequence, in which case the other 5m creates a pair wait.
Scoring
When aryanmen is won with the waiting tile not already present in hand, the wait can only be interpreted as a ryanmen wait, and it will score 0 fu.
When aryanmen is won with the waiting tile already present in hand, it can be interpreted as either a tanki or ryanmen wait. In this case, the highest-scoring option must be chosen. Normally, this will be the 2 fu for a tanki wait, but if the hand qualifies for the pinfu yaku, that will be scored instead.
