(Figs. 275 and 276)  
 Type host: Galerida cristata (Linnaeus) (Passeriformes: Alaudidae). Type locality: Poland.   
 Description. NON-PHYSOGASTRIC FEMALE (holotype). Total body length 700. Gnathosoma. Hypostomal apex with pair of blunt-ended protuberances. Podomers of palps densely punctate on ventral side. Peritremes Mhaped, each medial branch with 4–5 chambers, each lateral branch with 8–9 chambers. Movable cheliceral digit with several teeth in posterior part. Stylophore 185 long. Idiosoma. Propodonotal shield divided longitudinally into 2 narrow lateral shields, sparsely punctate, bearing bases of setae ve, si and se. Unpaired median shield absent. Setae vi situated distinctly posterior to level of setae ve. Propodonotal setae vi, ve and si smooth. Length ratio of setae vi: ve: si 1.2:1:1.4. Setae c1 located anterior to level of setae se. Setae d1 situated slightly closer to e2 than to d2. Pygidial shield well developed, apunctate, divided longitudinally. Setae f2 1.4 times longer than f1. Setae h1 4 times longer than f1. Alveoles of setae 3a–3a not coalesced. Genital plate well developed. Aggenital setae ag1 situated anterior to level of setae ag2. Length ratio of setae ag1: ag2: ag3 1:1:1.9. Setae ps1 and ps2 subequal in length, both 3.6 times shorter than genital setae. Genital setae hair-like, situated on genital lobes. Coxal fields well developed, I punctate, II–IV apunctate. Setae 3c 2.6 times longer than 3b. Legs. Dorsal leg setae smooth. Antaxial and paraxial members of claws pair III and IV unequal in size. Setae tc’ and tc” of legs III–IV subequal in length. Lengths of setae: vi 180, ve 155, si 215, se 255, c1 280, c2 280, d1 245, d2 255, e2 195, f1 70, f2 100, h1 295, h2 295, ps1 25, ps2 25, g1 90, 1a 60, 3a 35, ag1 75, ag2 70, ag3 130, l’RIII 30, l’RIV 30, tc’III–IV 75, tc”III–IV 75, 3b 45, 3c 115.   
MALE. Unknown.  
 Type material. Galerida cristata (Linnaeus) (Passeriformes: Alaudidae): female holotype (AMU –SYR.269) (bod.); POLAND, Zachodniopomorskie, near Swinoujscie, October 2001, coll. G. Kiljan.   
 Type deposition. Female holotype deposited in the AMU.   
 Etymology. The name of this species refers to the generic name of the host.   
 Differential diagnosis. This species is morphologically similar to P. eremophila described above. In females of both species the movable cheliceral digits are with cuticular processes in posterior part; genital setae are filiform, distinctly longer than pseudanal setae. P. galerida differs from P. eremophila by the characters as follow: in females of P. galerida, the antaxial and paraxial members of claws pair III and IV are unequal in size; the pygidial shield is divided longitudinally; the genital lobes are well developed. In females of P. eremophila, the antaxial and paraxial members of claws pair III and IV are subequal in size; the pygidial shield is not divided longitudinally; the genital lobes are absent.   
 Host range and habitat. Monoxenous species inhabiting quills of body feathers of Galerida cristata.   
 Distribution. Poland.
