Diagnostic characteristics:
– two dorsal shields, podosomal and pygidial shields
– posterior margin of podosomal shield is trilobed
– st1 st2 and st3 off the sternal shield
– subapical ventral setal pair on tarsus IV are relatively long strong spikes
– six pairs of ventral opisthosomal setae
– four pairs of mesolateral setae
– at least two pairs of mesolateral setae twice as long as other mesolateral setae
– subposterior pair of dorsal podosomal setae are less than half the length of the longest mesolateral setae
– paranal setae level with anal opening, paranal and postanal setae are equal or almost equal in length

– Ptilonyssus japuibensis and P. sairae are members of the “sairae” species complex. The species boundaries between the members of the “sairae” complex are very indistinct.
