Type material. Female holotype, 5 female, 4 male, and 6 nymph paratypes from quill of the Brown Creeper, Certhia americana Bonaparte (Certhiidae); United States, California, Monterey Co., 5 July 2001, coll. G. Spicer (GSS#98).
Type deposition. All material is deposited in the NMNH, except 2 female and 2 male paratypes in the AMU (AMU–SYR. 300).
Etymology. The species name refers to the generic name of the host.
Differential diagnosis. Syringophilopsis certhiae sp. nov. belongs to the turdus species group and is morphologically similar to S. sturni Chirov & Kravtsova, 1995 described ex Sturnus vulgaris Linnaeus (Sturnidae) from Kirghizia (Chirov & Kravtsova 1995). In females of both species, the hypostomal apex is ornamented by 1 pair of protuberances, the hysteronotal shields are present, and aggenital setae ag1 and ag2 are subequal in length and much longer than genital setae. The new species is distinguished from S. sturni by the following characters: in females of S. certhiae sp. nov., the length of the stylophore and movable cheliceral digit are 180–190 and 120–130 respectively, and the length ratio of setae g1:ag2 is 1:2.2–3. In females of S. sturni, the length of stylophore and movable cheliceral digit are 230–245 and 175–185 respectively, and the length ratio of setae g1:ag2 is 1:3.5–4.
