North American host records:
Strigidae:
Asio flammeus, Short-eared Owl (Knee et al. 2008) (has been recorded from A. flammeus in Russia by Butenko (1976))

Diagnostic characteristics:
- subposterior pair of dorsal podosomal setae on posterior margin of podosomal shield, and much < 70 Ám long
- posterior margin of sternal shield straight, st1 and st2 on shield, and shielding does not extend far beyond st1
- paranal setae anterior to anal opening, and postanal seta present

Note:
- R. alifanovi, R. brikinboricus, R. grandis, and R. nycteae comprise the Rhinoecius "grandis" species complex. These four species are difficult to separate. In particular, the sternal shield morphology used to separate species is not always consistent across individuals for a particular species. I find host species to be the best character to delineate among these species.
