Ptilonyssus (=Tyranninyssus) callinectoides (Brooks and Strandtmann, 1960)

North American host records:
Tyrannidae:
Myiarchus cinerascens, Ash-throated Flycatcher (Brooks and Strandtmann 1969; Pence 1975)
Myiarchus crinitus, Great Crested Flycatcher (Pence 1972, 1973, 1975; Knee et al. 2008)
Myiarchus tyrannulus, Brown-crested Flycatcher (Hyland and Moorhouse 1970)

Diagnostic characteristics:
– two dorsal shields, podosomal and fused opisthosomal and pygidial shields
– podosomal shield with lateral winglike processes
– posterior margin of podosomal shield is rounded
– opisthosomal shield is twice as long as wide
– lateral excavation of the posterior portion of the opisthosomal shield
– posterior margin of opisthosomal shield is rounded
– anterior margin of opisthosomal shield is straight
– st1 st2 and st3 on the sternal shield
– subapical ventral setal pair on tarsus IV are relatively long strong spikes with a rounded terminus
– four pairs of ventral opisthosomal setae
– two 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
– dorsum of genu III with oblique row of four stout spine setae close together
– paranal setae level with anal opening, paranal and postanal setae are unequal in length
