Material deposited in the AMU. Same host species: 1 female ( AVB 05–0715–010); FRANCE, Provence-Alpes-Côte d'Azur, Nice (43°42'00''N, 07°16'00''E), 1 April 1980, coll. J. Gaud. Material deposited in the ZISP. Same host species: 4 females; RUSSIA, Kaliningrad, Kurish spit, Rybachiy vill. (55°09'15"N, 20°51'14"E), 25 May 1982, coll. S.V. Mironov. Material deposited in the ZISP. Sylvia curruca : 4 female and 2 male paratypes of Syringophilopsis faini syn. nov. ( AVB 05–0714–030); KAZAKHSTAN, South-western Altai, Zyryanovskii Distr., near village of Shumovsk, 1 May 2000, coll. D. Apanaskevich. Material deposited in the ZISP.

Host range and habitat. The species is associated with sylviid hosts ( Sylviidae ) of the genus Sylvia : S. atricapilla , S. curruca and S. nisoria .

Distribution. France, Poland, Croatia, Russia, Kazakhstan and Jordan.

Remarks. I examined the type material of Syringophilopsis faini Bochkov and Apanaskevich, 2001 described from Sylvia curruca from Kazakhstan ( Bochkov & Apanaskevich 2001). S. faini has characters that perfectly correspond to those of A. sylviae , e.g. the hypostomal apex has 1 pair of the sausage-like median protuberances, apodemes I are parallel, the similar number of chambers in each branch of the peritremes and the lengths of setae. Therefore, I consider S. faini syn. nov. as an junior synonim of A. sylviae .
