Type material (not examined). Type material of S. presentalis is lost (pers. comm. Dr. A.V. Bochkov, ZISP) .

Non-type material examined. Sturnus vulgaris Linnaeus ( Passeriformes : Sturnidae ): 28 females, 8 males, 39 nymphs, 2 larvae ( AMU –SYR.124B) (sec.); POLAND, Zachodniopomorskie, Swinoujscie , May 2001, coll. G. Kiljan. Material deposited in the AMU and ZISP . Same host species: 12 females, 2 males, 24 nymphs ( AMU – SYR.124A) (sec.) ; SLOVAKIA, Bardejov , 25 March 1962, coll. T. Weisz. Material deposited in the AMU . Same host species: 1 female ( AVB 05–0715 – 032 ) ; FRANCE, Brittany, Cotes d'Armor (48°25'00''N, 02°40'00''W), 1 December 1993, coll. J.C. Beaucournu. Material deposited in the ZISP [ This specimen was previously incorectly determined as S. minor by Bochkov & Mironov (1998)] .

Host range and habitat. Monoxenous species occupying quills of secondary feathers of Sturnus vulgaris .

Distribution. France, Poland, Slovakia, and Kirghizia.

Remarks. This species was originally described from Sturnus vulgaris from Kirghizia ( Chirov & Kravtsova 1995). After description, Bochkov & Mironov (1998) reported this species also from Garrulus glandarius, but in the next paper (Bochkov 2001), the author reexamined the mite material from this host and assigned them as Syringophiloidus glandarii . In the paper by Glowska et al. 2007, incorrectly reported this species from T. merula . The mites inhabiting this host belong to a new species— S. parapresentalis sp. nov. (see below).
