Propodonotal shield well sclerotized, its surface sparsely punctate. Setae vi, ve, and si thin and smooth. Setae se and c1 lanceolate, enlarged in basal part ( Fig. 29 ). Setae vi and ve subequal in length, both 1.8–2.2 times shorter than si. Hysteronotal shield absent, punctate area near bases of setae d2 present. Pygidial shield punctate, bearing bases of setae f1, f2, h1, and h2. Setae h2 1.5 times longer than f2. Setae ag1 and ag3 1.2–1.4 times longer than ag2. Genital setae g1 and g2 subequal in length. Pseudanal setae ps1 and ps2 subequal in length. Cuticular striations as in Figs 26 and 27 . Legs. Coxal fields weakly sclerotized, punctate. Setae tc’ and tc” of legs III–IV subequal in length. Fan-like setae p’ and p” of legs III and IV with 7–9 tines ( Fig. 30 ). Setae 3c 3.2–3.6 times longer than 3b.

Propodonotal shield rectangular in shape, punctate in anterior part. Setae se situated anterior to level of setae c1. Setae vi, ve, and si subequal in length. Hysteronotal shield variable in shape, weakly sclerotized, not fused to pygidial shield. Small pygidial shield bearing bases of setae f2 and h2. Setae d2, d1 and e2 subequal in length. Setae h2 7.7 times longer than f2. Genital setae g1 situated anterior to level of setae g2. Setae ag1 and ag2 subequal in length. Cuticular striations as in Figs 33 and 34 . Legs. Coxal fields of legs I–IV punctate. Fan-like setae p’ and p” of legs III and IV with 6–8 tines ( Fig. 32 ). Length of setae: vi 15–20; ve 15–20; si 15–20; se 90; c1 90; c2 80; d1 10–15; d2 15, e2 10–15; f2 15; h2 115; ag1 45–50; ag2 40–50; ag3 25; tc’III–IV 25; tc”III–IV 25–35; sc3 20; sc4 15; 3b 20; 3c 25–40.

Type material. Female holotype, 2 female and 2 male paratypes ( AVB 08-1401-001) from Carduelis chloris (Linnaeus) ( Passeriformes : Fringillidae ); KAZAKHSTAN: Ongtustik Qazaqstan , Chockpak Ornithological Station, 1134 m, 42°30'45.2"N, 70°35'46.2"E, 23 October 2007, coll. P. Klimov.

Type deposition. Holotype, 1 female and 1 male paratypes are deposited at ZISP; 1 female paratype at AMU.

Etymology. This species is dedicated to Dr. Pavel B. Klimov (UMMZ), who collected this new species.

Differential diagnosis. Syringophiloidus cardueli sp. nov. is similar to S. erythrurus Skoracki, 2004 known from two estrildid hosts, Erythrura trichroa (Kittlitz) and Lonchura sp. ( Skoracki 2004a) . In females of both species, the infracapitulum is punctate, the lateral branches of the peritremes have 2–3 chambers each, setae vi and ve are thin and subequal in length, and two pairs of pseudanal setae are present. This new species differs from S. erythrurus by the following characters. In females of S. cardueli sp. nov., total body length is 680–705, setae si are about twice longer than vi and ve, the hysteronotal shield is absent, setae ag1 and ag3 are 1.2–1.4 times longer than ag2, and setae tc’ and tc” of legs III–IV are subequal in length. In females of S. erythrurus , total body length is 550–580, setae si are 5.4–6 times longer than vi and ve, the hysteronotal shield is present, setae ag1 and ag3 are 2–2.8 times longer than ag2, and setae tc”III–IV are 1.4–1.7 times longer than tc’III–IV.
