and flange-like. Notauli incomplete or ending in anterior half of axillae far from
scutellar margin; mesoscutal midlobe with paired setae; scutellum without submedian or

Biology: Usually secondary parasites of Lepidoptera through Hymenoptera, some primary parasites of Lepidoptera.
Comments: 6 described species. A very distinctive genus in the Nearctic fauna. Propodeal form is very similar to that of Notanisomorphella.
Comparative information:
Notanisomorphella: Clypeal margin not bilobed.
Dasyeulophus: Scutellum and midlobe of mesoscutum with numerous evenly or irregularly distributed setae (but scutellum often with as few as 2 pairs of distinct setae). Propodeum without plicae, and median carina weak.
Sympiesis: Clypeal margin not bilobed. Propodeum very seldom with strong median carina and plicae.
