Frameus obrienae – Festuca amplissima Rupr. ex Galeotti (Poaceae: Pooideae: Poeae).
Frameus porrectus – Muhlenbergia lucida Swallen

Plant names primarily according to The PLANTS Database (http://plants.usda.gov) (GRIN or the Plant List when not in PLANTS, internet search when all else fails).

Host records reported from Bartlett (2010)..

Economic Importance

 Limited – species poorly known.

Recognition

One of two New World genera with long heads. Most similar to Tanycranus, except that genus is from South America (not Mexico).  Frameus has the apex of the head blunt (not truncated) and the carinae of the frons paired to the frontoclypeal suture (as opposed to forked between or above eyes).  Frameus usually has two pairs of processes on segment 10 (except one on F. dissociatus, one on Tanycranus).
