FIGURES 24, 25 . Charadriphilus ralli sp. nov . Male. 24. Dorsal view; 25. Ventral view. 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.
