A new publication based on DNA sequence data finds cichlids are most closely related to Pholidichthys (Convict/Engineer gobies) and that these are a part of a larger group of fishes with adhesive eggs with chorionic filaments with a new name, Ovalentaria. The cool finding of this paper is that pharyngognathy, having pharyngeal jaws, has evolved multiple times. Pharyngognathy is one of the evolutionary 'innovations' that people cite as being at least partially responsible for the extreme diversity seen in fish groups like cichlids and labrids (Wrasses).
