North American host records:
Aphelocoma coerulescens, Florida Scrub-jay (Spicer 1978)
Cyanocitta stelleri, Stellar’s Jay (George 1961; Pence 1975)
Perisoreus canadensis, Gray Jay (George 1961; Pence 1975; Wilson and Haas 1980; Knee et al. 2008)

Diagnostic characteristics:
– two dorsal shields, podosomal and pygidial shields- posterior margin of podosomal shield is trilobed
– poorly defined sternal shield- subapical ventral setal pair on tarsus IV are relatively long strong spikes with a rounded terminus
– four pairs of ventral opisthosomal setae
– three pairs of mesolateral setae
– mesolateral setae all approximately equal in length, there are not two pairs of setae that are twice as long as another setal pair
– subposterior pair of dorsal podosomal setae are as long or almost as long as the longest mesolateral setae
– long seta with frayed tip dorsally on tarsus I apical margin
– paranal setae posterior to anal opening, and postanal seta absent
– pygidial shield is sometimes entire and sometimes in two fragments with subposterior setal pair on the fragments
