Type material (not examined). Type material of S. glandarii is lost ( Kethley 1970).

Non-type material examined. Garrulus glandarius Linnaeus ( Passeriformes : Corvidae ): 4 females and 3 males ( AVB 05–0715 – 036 ); RUSSIA, Smolensk, Kopanka (54°35'00"N, 032°04'00"E), 13 April 1959, collector unknown. Material deposited in the ZISP . Pica pica (Linnaeus) (Corvidae) : 7 females and 6 males ( AMU –SYR.60) (sec.); JAPAN, no other data. Material deposited in the AMU , host specimen is deposited in the MNHW. Corvus monedula Linnaeus (Corvidae) : 5 females and 3 males ( AVB 07–0110 – 003 ); KAZAKHSTAN, Ongtustik Qazaqstan, Chockpak Ornithological Station , elevation 1134 m. (42°30'45.2"N, 70°35'46.2"E), 1 October 2007, coll. A.V. Bochkov. Material deposited in the ZISP . Corvus frugileus Linnaeus (Corvidae) : 5 females, 3 males ( AVB 07–0110 – 004 ); KAZAKHSTAN, Ongtustik Qazaqstan, Chockpak Ornithological Station , elevation 1134 m. (42°30'45.2"N, 70°35'46.2"E), 1 October 2007, coll. A.V. Bochkov. Material deposited in the ZISP .

Host range and habitat. Oligoxenous species inhabiting quills of secondary feathers and restricted to corvid birds: Garrulus glandarius, Corvus monedula , C. frugilegus , and Pica pica .

Distribution. Germany, Russia, Kazakhstan, and Japan.

Remarks. This species was originally assigned by Fritsch (1956) as subspecies of Syringophilus minor . He reported it from two host species: Garrulus glandarius ( Corvidae ) and Coccothraustes coccothraustes (Corvidae) . The second host species mentioned by Fritsch is presently recognized as host for S. coccothraustes sp. nov. (see below), and is excluded from the list of hosts for S. glandarii .
