Lengths of setae: vi 40–55, ve 65–75, si 145–175, se 190–215, c1 180–190, c2 250, d1 30–40, d2 varriable 55-85 (in 3 specimens) or 165 (in 1 specimen), e2 30 –45, f2 30–40, h2 180–215, ag1 90–120, ag2 70–85, ag3 85–105, l’RIII 40–45, l’RIV 40–45, tc’III–IV 40–45, tc”III–IV 50–55.

Type material. Passer domesticus (Linnaeus) ( Passeriformes : Passeridae ): female holotype and 11 female, 4 male paratypes; KIRGHIZIA, Bishkek, coll. N. Kravtsova.

Type material deposition. Holotype and most of paratypes deposited in the ZISP, except 3 female paratypes in the AMU.

Host and habitat. Monoxenous species inhabiting quills of wing feathers of Passer domesticus .

Distribution. Kirghizia.

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

Differential diagnosis. S. passericus is morphologically similar to S. polioptilus . In females of both species the hypostomal apex is ornamented by 1 pair of median protuberances; aggenital setae ag1 and ag2 are subequal in length and longer than genital setae; setae ve are longer than ve; the hysteronotal shield is absent. This new species is distinguished from S. polioptilus by the following characters: in females of S. passericus , the infracapitulum is densely punctate; the lengths of stylophore and movable cheliceral digit are 235–245 and 170–180 respectively; a punctate area near base of setae d1 is absent; each fan-like setae p’ and p” of legs III and IV is with 12–13 tines; setae tc”III–IV and tc’III–IV are subequal in length; setae ag3 are 1.4–1.6 times longer than setae ag2. In females of S. polioptilus , the infracapitulum is apunctate; the lengths of stylophore and movable cheliceral digit are 190– 220 and 140 respectively; a punctate area near base of setae d1 is present; each fan-like setae p’ and p” of legs III and IV is with 9–10 tines; setae tc”III–IV are 1.4 times longer than tc’III–IV; setae ag3 are slightly (1.1 times) longer than setae ag2.
