What is Caulborn Premonition?

[Akasharose]

In Bestiary 3, page 48, the Caulborn has premonition listed as a Defensive ability. Yet, I see no description of this ability.

I did find a 3rd party spell Premonition - which does such things as you do not lose dex when flat-footed (but the bestiary stats clearly show a loss of the +4 dex for flat-footed).

Any help or knowledge about this would be appreciated. Thanks!

we encountered one today in Shattered Stars and the DM was wondering what the hell it was

I found this while looking around myself:

Premonition (Su) Once per day as an immediate action, a caulborn can receive a flash of insight that allows it to attempt to avoid a single attack. This premonition grants the caulborn a +2 insight bonus to AC and on Reflex saves.
