Sorry to wait so long on this post. I currently have a single specimen of the Psuetes poencilonotus. I also have Spilotes pullatus, and can say that they are very similar in behavior. Only they react a little differently when confronted, and tend to bite as a last resort where my Spilotes strike asap! lol Anyway, if you would like to know anything about them, I'd be glad to give you a hand.
