Setae se situated anterior to level of setae c1. Hysteronotal shield fused to pygidial shield, deeply concave on anterior margin, sparsely punctate. Setae d2 1.6–1.8 times longer than d1 and e2. Aggenital setal series represent by 2 pairs. Coxal fields I–IV sparsely punctate. Legs. Fan-like seta p’ and p” of legs III and IV with 7–9 tines ( Fig. 3 E). Lengths of setae: vi 30, ve 60–65, si 180–205, se 205–220, c1 195–200, c2 195–205, d1 35–40, d2 55–70, e2 35, f2 40, h2 250, ag1 80–95, ag2 85–105, l’RIII 40.

Type material. Female holotype, 6 female and 3 male paratypes (ZISP–AVB 011–2908–051) from secondary of Poecile palustris Linnaeus ( Passeriformes : Paridae ); RUSSIA, Primorsky Krai, Partizanskii District, Novolitovsk, 9 km N, 42º51’40”N; 132º53’5.5”E, 22 September 2008, coll. S.V. Mironov (SVM 08–0922–9/4).

Type material deposition. All material is deposited in the ZISP, except 2 female and 1 male paratypes in the AMU (AMU–SYR.428).

Etymology. The specific epithet “ pari ” refers to the family name of the host – Paridae .

Differential diagnosis. This new species is a representative of the elongatus species group characterized by long terminal setae f1, f2, h1 and h2. From 11 species belonging to this group, S. pari sp. nov. is closest to S. emberizae Fain, Bochkov et Mironov, 2000 described from Sicalis luteola (Sparrman) ( Passeriformes : Emberizidae ) from Rwanda (Fain et al. 2000). In females of both species, genital setae (g1 and g2) are long and subequal to aggenital setae ag2; the hypostomal apex bears 1 pair of minute protuberances, and the hysteronotal shields are absent. Syringophilopsis pari sp. nov. is distinguished from S. emberizae by the following features: in females of S. pari , the length of setae vi is 90–100; fan like setae p’ and p” of tarsi III and IV have 14–17 tines; in males, setae si are 180–205 long, and 2 pairs of aggenital setae are present. In females of S. emberizae , the length of setae vi is 67–78; fan like setae p’ and p” of tarsi III and IV have 20–23 tines; in males, setae si are 56–60 long, and three pairs of the aggenital setae are present.
