Type material. Pycnonotus xanthopygos (Ehrenberg) ( Passeriformes : Pycnonotidae ): female holotype and 3 female paratypes ( AMU –SYR.199) (sec.); JORDAN, Al-Dhleil near Amman, March 2002, coll. M. Skoracki.

Type material deposition. All type material deposited in the AMU .

Etymology. The name pycnonotus refers to the generic name of the host.

Host range and habitat. Monoxenous species inhabiting quills of secondary feathers of Pycnonotus xanthopygos.

Distribution. Jordan.

Differential diagnosis. Torotrogla pycnonotus is morphologically similar to T. merulae . In females of both species, setae f1 and h1 are short and subequal in the length; bases of setae d1 are situated on the hysteronotal shield and setae l’ of trochanters III and IV extending beyond the respective genua. This new species is distinguished as follows: in females of T. pycnonotus , setae vi and ve are subequal in the length; the hypostomal apex bears a pair of short, wide and sharp-ended protuberances; the pygidial shield is distinctly punctate. In females of T. merulae , setae ve are twice as long as setae vi; the hypostomal apex is ornamented by a pair of long, slender and sharp-ended protuberances; the pygidial shield is apunctate.
