Dopterians also shared an unusual resemblance to the Kobheerian species; their appearance was almost identical, but Dopterians had Ferengi-like noses, whereas Kobheerians had two large, elongated flat nostrils in the place of a nose.
The Dopterians apparently have an automated attack weapon known as a "Dopterian interceptor" according to DS9: "Business as Usual". The name was not verbally given on screen, however, the attacking device was identified as such in the script.
According to the Star Trek: Star Charts, on the star chart United Federation of Planets I, the Dopterians were from the Dopteria (Kappa Coronae Borealis) system. This system was located in the Alpha Quadrant.
