Type material. Phoenicurus ochruros (Gmelin) ( Passeriformes : Turdidae ): female holotype, 8 female and 2 male paratypes ( AMU –SYR.237) (sec.); POLAND, Zachodniopomorskie, Weltyn , May 2001, coll G. Kiljan .

Type deposition. Holotype deposited in the AMU, paratypes in the AMU and ZISP.

Host range and habitat. Monoxenous species inhabiting quills of secondary feathers of Phoenicurus ochruros .

Distribution. Poland.

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

Differential diagnosis. This new species is morphologically similar to Syringophiloidus schoeniclus . In females of both species each lateral branch of the peritremes has 13 chambers; all shields on the dorsum and coxal fields are punctate. Females of this new species are distinguished from S. schoeniclus by the following characters: in females of S. phoenicurus , aggenital setae ag1 and ag2 are subequal in the length; setae c1, c2 and d1 are shorter than 170; movable cheliceral digit is 110–115 long. In females of S. schoeniclus , aggenital setae ag1 are 1.6–1.8 times longer than ag2; setae c1, c2 and d1 are longer than 190; movable cheliceral digit is 140 long.
