(Figs. 14–25)  
 Description. FEMALE. Body length of holotype 665 (665–670 in 10 paratypes). Gnathosoma. Infracapitulum not punctate. Hypostomal apex smooth (Fig. 16). Each transverse branch of peritremes with 3 chambers, each longitudinal branch with 6–7 chambers (Fig. 17). Stylophore constricted posteriorly, 215 (215–220) long. Idiosoma. Propodonotal shield weakly sclerotized, striae visible, sparse punctate, bearing bases of setae vi, ve, si, se, and c1. Setae c2 situated close to this shield. Setae se located slightly posterior to level of setae c1. Length ratio of setae vi: ve: si 1:1.8–2:2.5–3.2. Hysteronotal shield wide, particularly in posterior part, not punctate. Hysteronotal setae d1, d2, and e2 subequal in length. Setae f2 situated distinctly anterior to level of setae f1. Setae h1 and f1 subequal in length. Setae h2 1.5–1.7 times longer than f2. Length ratio of aggenital setae ag1: ag2: ag3 1.5–1.7:1:1.8–2.4. Genital setae g1 and g2 subequal in length, both 1.2– 1.5 times longer than pseudanal setae ps1 and ps2. Cuticular striations as in Figs 14 and 15. Legs. Coxal fields of legs I and II well sclerotized, III–IV weakly sclerotized, all without punctations. Setae tc”III–IV about twice longer than tc’III–IV. Fan-like setae p’ and p” of legs III and IV with 6–8 tines (Fig. 21). Setae 3c 2.2– 2.3 times longer than 3b. Apodemes III and IV present (Fig. 19). Length of setae: vi (20–35); ve 50 (45–55); si 85 (75–85); se (155); c1 (190); c2 265 (230–260); d1 135 (130–150); d2 140 (130–155); e2 135 (135–155); f1 35 (35); f2 280 (230–260); h1 30 (30–35); h2 415 (385–405); ps1 and ps2 25 (20–25); g1 and g2 30 (30); ag1 90 (90–95); ag2 60 (55–60); ag3 105 (110–130); tc’III–IV 30 (30–35); tc”III–IV 65 (60–65); 3b 30 (30); 3c 70 (65–70).   
 MALE. Total body length 545–555 in 10 paratypes. Gnathosoma. Infracapitulum not punctate. Hypostomal apex smooth (Fig. 20). Each transverse branch of peritremes with 3 chambers, each longitudinal branch with 7–8 chambers (Fig. 23). Stylophore constricted posteriorly, 170–180 long. Idiosoma. Propodonotal shield slightly punctated, represented by pair of small plates bearing bases of setae vi, ve and si or entirely absent. Setae se situated anterior to level of setae c1. Hysteronotal shield weakly sclerotized, fused to pygidial shield, not punctate, bearing bases of setae d1, e2, f2, and h2. Setae d2 variable in length but always longer than setae d1 and e2. Setae h2 10–13 times longer than f2. Genital setae g1 and g2 situated at same transverse level. Setae ag1 longer than ag2 and ag3. Setae ag2 and ag3 situated on dorsal side. Cuticular striations as in Figs 24 and 25. Legs. Coxal fields of legs I–IV not punctate. Fan-like setae p’ and p” of legs III and IV with 7 tines (Fig. 21). Length of setae: vi 30; ve 35–40; si 60–75; se 140–155; c1 135–155; c2 165– 170; d1 15–20; d2 70–125, e2 15–20; f2 15–20; h2 190–210; ag1 65–80; ag2 43–40; ag3 35–45; tc’III–IV 25; tc”III–IV 45–55; sc3 35–45; sc4 20–25; 3b 25; 3c 65.   
 Type material. Female holotype, 10 female and 10 male paratypes (AVB 07-2610-122) from Rallus aquaticus Linnaeus (Gruiformes: Rallidae); KAZAKHSTAN: Ongtustik Qazaqstan, Vysokoe village, Vysochanskiy Pond, 42°30'50.2''N, 70°35'52.8''E, 26 October 2007, coll. P. Klimov.   
 Type deposition. Holotype, 6 female and 6 male paratypes are deposited at ZISP; 2 female and 2 male paratypes at AMU; 2 female and 2 male paratypes at UMMZ.   
 Etymology. The name ralli refers to the generic name of the host.   
 Differential diagnosis. Charadriphilus ralli sp. nov. is morphologically similar to Ch. paraguaiae (Skoracki and Sikora, 2002) described from Gallinago paraguaiae Viellot (Charadriiformes: Scolopacidae) from Argentina (Skoracki & Sikora 2002). In females of both species, each lateral branch of the peritremes has 3 chambers, each longitudinal branch has 6–7 chambers, and aggenital setae ag2 are shorter than ag1 and ag3. This new species differs from Ch. paraguaiae by the following characters. In females of Ch. ralli sp. nov., the infracapitulum and coxal fields are not punctated, length of the stylophore is approximately 215, the propodonotal shield is rectangular in shape, the length ratio of setae vi: ve: si is 1:1.8–2:2.5–3.2, and the hysteronotal shield is well sclerotized and bears seta d1 and e2 bases. In females of Ch. paraguaiae, the infracapitulum and coxal fields are punctated, the length of stylophore is approximately 135, the anterior margin of the propodonotal shield has a deep cleft, the length ratio of setae vi: ve: si is 1:1:1, and the hysteronotal shield is weakly sclerotized and bears only setae d1 bases.
