I don't see enough details to run it through the key to the 100+ North American species of Delia. Does D. platura have any distinctive features? |

The fore-tibia has a curved blunt apical spur in the posteroventral zone (shared with some other species); no extra hairs in the notopleural depression; pre-alar seta present; the hind tibia has a complete row of about 20 erect pv setulose hairs of equal length; The hind femur has av setae (4-6) confined to distal half; there's a distinct dark brownish median vitta on the scutum. Edit: all this is for males only
