In the script of "A Simple Investigation", the two green-skinned thugs working for Draim were identified as Finneans. However, Arissa and Odo reviewed the security recordings of the stationairlocks for suspicious persons possibly related to Draim and found nothing. One would presume that Finneans showing up on the station would have aroused their interest. Further, Arissa (who appeared Human) supposedly grew up on Finnea. Finally, the Idanian operative Tauvid Rem who was murdered by the thugs did not give the appearance of concern we might expect at having two Finneans show up at his door on DS9, given the situation.
This species also shares many similar physical attributes as were seen in Pomet's species.
